## [Unreleased]
|
||||
|
||||
### Added
|
||||
- Automatic detection of CPU intrisics when building with -arch=native
|
||||
- An option to print cached variables from CMake
|
||||
- Add support for compiling on Mac (and clang)
|
||||
- An option for resetting stalled validation metrics
|
||||
- Add CMAKE options to disable compilation for specific GPU SM types
|
||||
- An option to print word-level translation scores
|
||||
- An option to turn off automatic detokenization from SentencePiece
|
||||
- Separate quantization types for 8-bit FBGEMM for AVX2 and AVX512
|
||||
- Sequence-level unliklihood training
|
||||
- Allow file name templated valid-translation-output files
|
||||
- Support for lexical shortlists in marian-server
|
||||
- Support for 8-bit matrix multiplication with FBGEMM
|
||||
- CMakeLists.txt now looks for SSE 4.2
|
||||
- Purging of finished hypotheses during beam-search. A lot faster for large batches.
|
||||
- Faster option look-up, up to 20-30% faster translation
|
||||
- Added --cite and --authors flag
|
||||
- Added optional support for ccache
|
||||
- Switch to change abort to exception, only to be used in library mode
|
||||
- Support for 16-bit packed models with FBGEMM
|
||||
- Multiple separated parameter types in ExpressionGraph, currently inference-only
|
||||
- Safe handling of sigterm signal
|
||||
- Automatic vectorization of elementwise operations on CPU for tensors dims that
|
||||
are divisible by 4 (AVX) and 8 (AVX2)
|
||||
- Replacing std::shared_ptr<T> with custom IntrusivePtr<T> for small objects like
|
||||
Tensors, Hypotheses and Expressions.
|
||||
- Fp16 inference working for translation
|
||||
- Gradient-checkpointing
|
||||
|
||||
### Fixed
|
||||
- Windows build with recent changes
|
||||
- Bug with read-ahead buffer
|
||||
- Fixed handling of "dump-config: false" in YAML config
|
||||
- Errors due to warnings
|
||||
- Fixed issue concerning failed saving with single GPU training and --sync-sgd option.
|
||||
- Replace value for INVALID_PATH_SCORE with std::numer_limits<float>::lowest()
|
||||
to avoid overflow with long sequences
|
||||
- Break up potential circular references for GraphGroup*
|
||||
- Fix empty source batch entries with batch purging
|
||||
- Clear RNN chache in transformer model, add correct hash functions to nodes
|
||||
- Gather-operation for all index sizes
|
||||
- Fix word weighting with max length cropping
|
||||
- Fixed compilation on CPUs without support for AVX
|
||||
- FastOpt now reads "n" and "y" values as strings, not as boolean values
|
||||
- Fixed multiple reduction kernels on GPU
|
||||
- Fixed guided-alignment training with cross-entropy
|
||||
- Replace IntrusivePtr with std::uniq_ptr in FastOpt, fixes random segfaults
|
||||
due to thread-non-safty of reference counting.
|
||||
- Make sure that items are 256-byte aligned during saving
|
||||
- Make explicit matmul functions respect setting of cublasMathMode
|
||||
- Fix memory mapping for mixed paramter models
|
||||
- Removed naked pointer and potential memory-leak from file_stream.{cpp,h}
|
||||
- Compilation for GCC >= 7 due to exception thrown in destructor
|
||||
- Sort parameters by lexicographical order during allocation to ensure consistent
|
||||
memory-layout during allocation, loading, saving.
|
||||
- Output empty line when input is empty line. Previous behavior might result in
|
||||
hallucinated outputs.
|
||||
- Compilation with CUDA 10.1
|
||||
|
||||
### Changed
|
||||
- Combine two for-loops in nth_element.cpp on CPU
|
||||
- Revert LayerNorm eps to old position, i.e. sigma' = sqrt(sigma^2 + eps)
|
||||
- Downgrade NCCL to 2.3.7 as 2.4.2 is buggy (hangs with larger models)
|
||||
- Return error signal on SIGTERM
|
||||
- Dropped support for CUDA 8.0, CUDA 9.0 is now minimal requirement
|
||||
- Removed autotuner for now, will be switched back on later
|
||||
- Boost depdendency is now optional and only required for marian_server
|
||||
- Dropped support for g++-4.9
|
||||
- Simplified file stream and temporary file handling
|
||||
- Unified node intializers, same function API.
|
||||
- Remove overstuff/understuff code
|
||||
|
||||

========
|
||||
|
||||
#### 16 bit floating-point data type for C++ ####
|
||||
|
||||
Implements a `HalfFloat` class that implements all the common arithmetic operations for a 16 bit
|
||||
floating-point type (10 bits mantissa, 5 bits exponent and one sign bit) and can thus be used (almost)
|
||||
interchangeably with regular `float`s. Not all operations have efficent implementations (some just convert to `float`,
|
||||
compute the result and convert back again) - if in doubt, check out the source code.
|
||||
|
||||
The implementation tries to adhere to IEEE 754 in that it supports NaN and Infinity, but fails in other points:
|
||||
|
||||
- no difference between qnan and snan
|
||||
- no traps
|
||||
- no well-defined rounding mode
|
||||
|
||||
|
||||
We also supply a specialization for `std::numeric_limits<half>` that `half` be usable in template code
|
||||
dependent on type traits.
|
||||
|
||||
|
||||
#### Usage ####
|
||||
|
||||
// get some halfs (half is a typedef for HalfFloat)
|
||||
half a = 1.0f;
|
||||
half b = 0.5f;
|
||||
|
||||
// and have some FUN
|
||||
half c = (a+b) / (a-b);
|
||||
++c;
|
||||
|
||||
// now that we have a result in loosy precision,
|
||||
// convert it back to double precision.
|
||||
// if anybody asks, it's for the lulz.
|
||||
double result = c;
|
||||
|
||||
|
||||

# mio
|
||||
An easy to use header-only cross-platform C++11 memory mapping library with an MIT license.
|
||||
|
||||
mio has been created with the goal to be easily includable (i.e. no dependencies) in any C++ project that needs memory mapped file IO without the need to pull in Boost.
|
||||
|
||||
Please feel free to open an issue, I'll try to address any concerns as best I can.
|
||||
|
||||
### Why?
|
||||
Because memory mapping is the best thing since sliced bread!
|
||||
|
||||
More seriously, the primary motivation for writing this library instead of using Boost.Iostreams, was the lack of support for establishing a memory mapping with an already open file handle/descriptor. This is possible with mio.
|
||||
|
||||
Furthermore, Boost.Iostreams' solution requires that the user pick offsets exactly at page boundaries, which is cumbersome and error prone. mio, on the other hand, manages this internally, accepting any offset and finding the nearest page boundary.
|
||||
|
||||
Albeit a minor nitpick, Boost.Iostreams implements memory mapped file IO with a `std::shared_ptr` to provide shared semantics, even if not needed, and the overhead of the heap allocation may be unnecessary and/or unwanted.
|
||||
In mio, there are two classes to cover the two use-cases: one that is move-only (basically a zero-cost abstraction over the system specific mmapping functions), and the other that acts just like its Boost.Iostreams counterpart, with shared semantics.
|
||||
|
||||
### How to create a mapping
|
||||
NOTE: the file must exist before creating a mapping.
|
||||
|
||||
There are three ways to map a file into memory:
|
||||
|
||||
- Using the constructor, which throws a `std::system_error` on failure:
|
||||
```c++
|
||||
mio::mmap_source mmap(path, offset, size_to_map);
|
||||
```
|
||||
or you can omit the `offset` and `size_to_map` arguments, in which case the
|
||||
entire file is mapped:
|
||||
```c++
|
||||
mio::mmap_source mmap(path);
|
||||
```
|
||||
|
||||
- Using the factory function:
|
||||
```c++
|
||||
std::error_code error;
|
||||
mio::mmap_source mmap = mio::make_mmap_source(path, offset, size_to_map, error);
|
||||
```
|
||||
or:
|
||||
```c++
|
||||
mio::mmap_source mmap = mio::make_mmap_source(path, error);
|
||||
```
|
||||
|
||||
- Using the `map` member function:
|
||||
```c++
|
||||
std::error_code error;
|
||||
mio::mmap_source mmap;
|
||||
mmap.map(path, offset, size_to_map, error);
|
||||
```
|
||||
or:
|
||||
```c++
|
||||
mmap.map(path, error);
|
||||
```
|
||||
**NOTE:** The constructors **require** exceptions to be enabled. If you prefer
|
||||
to build your projects with `-fno-exceptions`, you can still use the other ways.
|
||||
|
||||
Moreover, in each case, you can provide either some string type for the file's path, or you can use an existing, valid file handle.
|
||||
```c++
|
||||
#include <sys/types.h>
|
||||
#include <sys/stat.h>
|
||||
#include <fcntl.h>
|
||||
#include <mio/mmap.hpp>
|
||||
#include <algorithm>
|
||||
|
||||
int main()
|
||||
{
|
||||
// NOTE: error handling omitted for brevity.
|
||||
const int fd = open("file.txt", O_RDONLY);
|
||||
mio::mmap_source mmap(fd, 0, mio::map_entire_file);
|
||||
// ...
|
||||
}
|
||||
```
|
||||
However, mio does not check whether the provided file descriptor has the same access permissions as the desired mapping, so the mapping may fail. Such errors are reported via the `std::error_code` out parameter that is passed to the mapping function.
|
||||
|
||||
**WINDOWS USERS**: This library *does* support the use of wide character types
|
||||
for functions where character strings are expected (e.g. path parameters).
|
||||
|
||||
### Example
|
||||
|
||||
```c++
|
||||
#include <mio/mmap.hpp>
|
||||
#include <system_error> // for std::error_code
|
||||
#include <cstdio> // for std::printf
|
||||
#include <cassert>
|
||||
#include <algorithm>
|
||||
#include <fstream>
|
||||
|
||||
int handle_error(const std::error_code& error);
|
||||
void allocate_file(const std::string& path, const int size);
|
||||
|
||||
int main()
|
||||
{
|
||||
const auto path = "file.txt";
|
||||
|
||||
// NOTE: mio does *not* create the file for you if it doesn't exist! You
|
||||
// must ensure that the file exists before establishing a mapping. It
|
||||
// must also be non-empty. So for illustrative purposes the file is
|
||||
// created now.
|
||||
allocate_file(path, 155);
|
||||
|
||||
// Read-write memory map the whole file by using `map_entire_file` where the
|
||||
// length of the mapping is otherwise expected, with the factory method.
|
||||
std::error_code error;
|
||||
mio::mmap_sink rw_mmap = mio::make_mmap_sink(
|
||||
path, 0, mio::map_entire_file, error);
|
||||
if (error) { return handle_error(error); }
|
||||
|
||||
// You can use any iterator based function.
|
||||
std::fill(rw_mmap.begin(), rw_mmap.end(), 'a');
|
||||
|
||||
// Or manually iterate through the mapped region just as if it were any other
|
||||
// container, and change each byte's value (since this is a read-write mapping).
|
||||
for (auto& b : rw_mmap) {
|
||||
b += 10;
|
||||
}
|
||||
|
||||
// Or just change one value with the subscript operator.
|
||||
const int answer_index = rw_mmap.size() / 2;
|
||||
rw_mmap[answer_index] = 42;
|
||||
|
||||
// Don't forget to flush changes to disk before unmapping. However, if
|
||||
// `rw_mmap` were to go out of scope at this point, the destructor would also
|
||||
// automatically invoke `sync` before `unmap`.
|
||||
rw_mmap.sync(error);
|
||||
if (error) { return handle_error(error); }
|
||||
|
||||
// We can then remove the mapping, after which rw_mmap will be in a default
|
||||
// constructed state, i.e. this and the above call to `sync` have the same
|
||||
// effect as if the destructor had been invoked.
|
||||
rw_mmap.unmap();
|
||||
|
||||
// Now create the same mapping, but in read-only mode. Note that calling the
|
||||
// overload without the offset and file length parameters maps the entire
|
||||
// file.
|
||||
mio::mmap_source ro_mmap;
|
||||
ro_mmap.map(path, error);
|
||||
if (error) { return handle_error(error); }
|
||||
|
||||
const int the_answer_to_everything = ro_mmap[answer_index];
|
||||
assert(the_answer_to_everything == 42);
|
||||
}
|
||||
|
||||
int handle_error(const std::error_code& error)
|
||||
{
|
||||
const auto& errmsg = error.message();
|
||||
std::printf("error mapping file: %s, exiting...\n", errmsg.c_str());
|
||||
return error.value();
|
||||
}
|
||||
|
||||
void allocate_file(const std::string& path, const int size)
|
||||
{
|
||||
std::ofstream file(path);
|
||||
std::string s(size, '0');
|
||||
file << s;
|
||||
}
|
||||
```
|
||||
|
||||
`mio::basic_mmap` is move-only, but if multiple copies to the same mapping are needed, use `mio::basic_shared_mmap` which has `std::shared_ptr` semantics and has the same interface as `mio::basic_mmap`.
|
||||
```c++
|
||||
#include <mio/shared_mmap.hpp>
|
||||
|
||||
mio::shared_mmap_source shared_mmap1("path", offset, size_to_map);
|
||||
mio::shared_mmap_source shared_mmap2(std::move(mmap1)); // or use operator=
|
||||
mio::shared_mmap_source shared_mmap3(std::make_shared<mio::mmap_source>(mmap1)); // or use operator=
|
||||
mio::shared_mmap_source shared_mmap4;
|
||||
shared_mmap4.map("path", offset, size_to_map, error);
|
||||
```
|
||||
|
||||
It's possible to define the type of a byte (which has to be the same width as `char`), though aliases for the most common ones are provided by default:
|
||||
```c++
|
||||
using mmap_source = basic_mmap_source<char>;
|
||||
using ummap_source = basic_mmap_source<unsigned char>;
|
||||
|
||||
using mmap_sink = basic_mmap_sink<char>;
|
||||
using ummap_sink = basic_mmap_sink<unsigned char>;
|
||||
```
|
||||
But it may be useful to define your own types, say when using the new `std::byte` type in C++17:
|
||||
```c++
|
||||
using mmap_source = mio::basic_mmap_source<std::byte>;
|
||||
using mmap_sink = mio::basic_mmap_sink<std::byte>;
|
||||
```
|
||||
|
||||
Though generally not needed, since mio maps users requested offsets to page boundaries, you can query the underlying system's page allocation granularity by invoking `mio::page_size()`, which is located in `mio/page.hpp`.
|
||||
|
||||
### Single Header File
|
||||
Mio can be added to your project as a single header file simply by including `\single_include\mio\mio.hpp`. Single header files can be regenerated at any time by running the `amalgamate.py` script within `\third_party`.
|
||||
```
|
||||
python amalgamate.py -c config.json -s ../include
|
||||
```
|
||||
|
||||
## CMake
|
||||
As a header-only library, mio has no compiled components. Nevertheless, a [CMake](https://cmake.org/overview/) build system is provided to allow easy testing, installation, and subproject composition on many platforms and operating systems.
|
||||
|
||||
### Testing
|
||||
Mio is distributed with a small suite of tests and examples.
|
||||
When mio is configured as the highest level CMake project, this suite of executables is built by default.
|
||||
Mio's test executables are integrated with the CMake test driver program, [CTest](https://cmake.org/cmake/help/latest/manual/ctest.1.html).
|
||||
|
||||
CMake supports a number of backends for compilation and linking.
|
||||
|
||||
To use a static configuration build tool, such as GNU Make or Ninja:
|
||||
|
||||
```sh
|
||||
cd <mio source directory>
|
||||
mkdir build
|
||||
cd build
|
||||
|
||||
# Configure the build
|
||||
cmake -D CMAKE_BUILD_TYPE=<Debug | Release> \
|
||||
-G <"Unix Makefiles" | "Ninja"> ..
|
||||
|
||||
# build the tests
|
||||
< make | ninja | cmake --build . >
|
||||
|
||||
# run the tests
|
||||
< make test | ninja test | cmake --build . --target test | ctest >
|
||||
```
|
||||
|
||||
To use a dynamic configuration build tool, such as Visual Studio or Xcode:
|
||||
|
||||
```sh
|
||||
cd <mio source directory>
|
||||
mkdir build
|
||||
cd build
|
||||
|
||||
# Configure the build
|
||||
cmake -G <"Visual Studio 14 2015 Win64" | "Xcode"> ..
|
||||
|
||||
# build the tests
|
||||
cmake --build . --config <Debug | Release>
|
||||
|
||||
# run the tests via ctest...
|
||||
ctest --build-config <Debug | Release>
|
||||
|
||||
# ... or via CMake build tool mode...
|
||||
cmake --build . --config <Debug | Release> --target test
|
||||
```
|
||||
|
||||
Of course the **build** and **test** steps can also be executed via the **all** and **test** targets, respectively, from within the IDE after opening the project file generated during the configuration step.
|
||||
|
||||
Mio's testing is also configured to operate as a client to the [CDash](https://www.cdash.org/) software quality dashboard application. Please see the [Kitware documentation](https://cmake.org/cmake/help/latest/manual/ctest.1.html#dashboard-client) for more information on this mode of operation.
|
||||
|
||||
### Installation
|
||||
|
||||
Mio's build system provides an installation target and support for downstream consumption via CMake's [`find_package`](https://cmake.org/cmake/help/v3.0/command/find_package.html) intrinsic function.
|
||||
CMake allows installation to an arbitrary location, which may be specified by defining `CMAKE_INSTALL_PREFIX` at configure time.
|
||||
In the absense of a user specification, CMake will install mio to conventional location based on the platform operating system.
|
||||
|
||||
To use a static configuration build tool, such as GNU Make or Ninja:
|
||||
|
||||
```sh
|
||||
cd <mio source directory>
|
||||
mkdir build
|
||||
cd build
|
||||
|
||||
# Configure the build
|
||||
cmake [-D CMAKE_INSTALL_PREFIX="path/to/installation"] \
|
||||
[-D BUILD_TESTING=False] \
|
||||
-D CMAKE_BUILD_TYPE=Release \
|
||||
-G <"Unix Makefiles" | "Ninja"> ..
|
||||
|
||||
# install mio
|
||||
<make install | ninja install | cmake --build . --target install>
|
||||
```
|
||||
|
||||
To use a dynamic configuration build tool, such as Visual Studio or Xcode:
|
||||
|
||||
```sh
|
||||
cd <mio source directory>
|
||||
mkdir build
|
||||
cd build
|
||||
|
||||
# Configure the project
|
||||
cmake [-D CMAKE_INSTALL_PREFIX="path/to/installation"] \
|
||||
[-D BUILD_TESTING=False] \
|
||||
-G <"Visual Studio 14 2015 Win64" | "Xcode"> ..
|
||||
|
||||
# install mio
|
||||
cmake --build . --config Release --target install
|
||||
```
|
||||
|
||||
Note that the last command of the installation sequence may require administrator privileges (e.g. `sudo`) if the installation root directory lies outside your home directory.
|
||||
|
||||
This installation
|
||||
+ copies the mio header files to the `include/mio` subdirectory of the installation root
|
||||
+ generates and copies several CMake configuration files to the `share/cmake/mio` subdirectory of the installation root
|
||||
|
||||
This latter step allows downstream CMake projects to consume mio via `find_package`, e.g.
|
||||
|
||||
```cmake
|
||||
find_package( mio REQUIRED )
|
||||
target_link_libraries( MyTarget PUBLIC mio::mio )
|
||||
```
|
||||
|
||||
**WINDOWS USERS**: The `mio::mio` target `#define`s `WIN32_LEAN_AND_MEAN` and `NOMINMAX`. The former ensures the imported surface area of the Win API is minimal, and the latter disables Windows' `min` and `max` macros so they don't intefere with `std::min` and `std::max`. Because *mio* is a header only library, these defintions will leak into downstream CMake builds. If their presence is causing problems with your build then you can use the alternative `mio::mio_full_winapi` target, which adds none of these defintions.
|
||||
|
||||
If mio was installed to a non-conventional location, it may be necessary for downstream projects to specify the mio installation root directory via either
|
||||
|
||||
+ the `CMAKE_PREFIX_PATH` configuration option,
|
||||
+ the `CMAKE_PREFIX_PATH` environment variable, or
|
||||
+ `mio_DIR` environment variable.
|
||||
|
||||
Please see the [Kitware documentation](https://cmake.org/cmake/help/v3.0/command/find_package.html) for more information.
|
||||
|
||||
In addition, mio supports packaged relocatable installations via [CPack](https://cmake.org/cmake/help/latest/manual/cpack.1.html).
|
||||
Following configuration, from the build directory, invoke cpack as follows to generate a packaged installation:
|
||||
|
||||
```sh
|
||||
cpack -G <generator name> -C Release
|
||||
```
|
||||
|
||||
The list of supported generators varies from platform to platform. See the output of `cpack --help` for a complete list of supported generators on your platform.
|
||||
|
||||
### Subproject Composition
|
||||
To use mio as a subproject, copy the mio repository to your project's dependencies/externals folder.
|
||||
If your project is version controlled using git, a git submodule or git subtree can be used to syncronize with the updstream repository.
|
||||
The [use](https://services.github.com/on-demand/downloads/submodule-vs-subtree-cheat-sheet/) and [relative advantages](https://andrey.nering.com.br/2016/git-submodules-vs-subtrees/) of these git facilities is beyond the scope of this document, but in brief, each may be established as follows:
|
||||
|
||||
```sh
|
||||
# via git submodule
|
||||
cd <my project's dependencies directory>
|
||||
git submodule add -b master https://github.com/mandreyel/mio.git
|
||||
|
||||
# via git subtree
|
||||
cd <my project's root directory>
|
||||
git subtree add --prefix <path/to/dependencies>/mio \
|
||||
https://github.com/mandreyel/mio.git master --squash
|
||||
```
|
||||
|
||||
Given a mio subdirectory in a project, simply add the following lines to your project's to add mio include directories to your target's include path.
|
||||
|
||||
```cmake
|
||||
add_subdirectory( path/to/mio/ )
|
||||
target_link_libraries( MyTarget PUBLIC <mio::mio | mio> )
|
||||
```
|
||||
|
||||
Note that, as a subproject, mio's tests and examples will not be built and CPack integration is deferred to the host project.

# Introduction #
|
||||
|
||||
This is a simple implementation of the CHD perfect hash algorithm. CHD can
|
||||
generate perfect hash functions for very large key sets--on the order of
|
||||
millions of keys--in a very short time. On my circa 2012 desktop and using
|
||||
the default parameters (hash load factor of 80% and average displacement map
|
||||
bucket load of 4.0 keys) this implementation can generate a hash function
|
||||
for 1,000 keys in less than 1/100th of a second, and 1,000,000 keys in less
|
||||
than a second.
|
||||
|
||||
For more information about the algorithm, see
|
||||
http://cmph.sourceforge.net/chd.html.
|
||||
|
||||
# Dependencies #
|
||||
|
||||
* No runtime dependencies.
|
||||
* Requires a modern C++ compiler to build.
|
||||
* The included build requires GNU Make.
|
||||
|
||||
# Building #
|
||||
|
||||
## Make Macros ##
|
||||
|
||||
The typical GNU macros can be used control the build.
|
||||
|
||||
### Compilation ###
|
||||
|
||||
Note that the modules for Lua 5.1, 5.2, and 5.3 can be built simultaneously.
|
||||
|
||||
* CXX: C++ compiler path.
|
||||
* CXXFLAGS: C++ compiler flags.
|
||||
* CPPFLAGS: C preprocessor flags. Necessary if Lua API cannot be discovered
|
||||
automatically. You can specify multiple include paths if building more than
|
||||
one Lua module.
|
||||
* LDFLAGS: Linker flags. Not normally needed.
|
||||
* SOFLAGS: Flags needed to build dynamic library.
|
||||
* LOFLAGS: Flags needed to build loadable module. Normally should be the
|
||||
same as SOFLAGS, except on OS X.
|
||||
* LIBS: Library dependencies. Normally empty, but see the section Avoiding
|
||||
C++ Dependencies.
|
||||
|
||||
#### Avoiding C++ Dependencies
|
||||
|
||||
Defining the preprocessor macro PHF_NO_LIBCXX to 1 will prevent usage of C++
|
||||
interfaces such as std::string that would require a dependency on libc++ or
|
||||
libstdc++. This allows using platform-dependent flags in CXXFLAGS, LDFLAGS,
|
||||
and SOFLAGS to prevent a dependency on the system C++ library.
|
||||
|
||||
For example, on OS X you can do:
|
||||
```sh
|
||||
$ make CPPFLAGS="-DPHF_NO_LIBCXX" \
|
||||
CXXFLAGS="-std=c++11 -fno-rtti -fno-exceptions -O3 -march=native" \
|
||||
LDFLAGS="-nostdlib" \
|
||||
LIBS="-lSystem"
|
||||

# Usage #
|
||||
|
||||
## Lua ##
|
||||
|
||||
## API ###
|
||||
|
||||
### phf.new(keys[, lambda][, alpha][, seed][, nodiv]) ###
|
||||
|
||||
* keys: array of keys in order from 1..#keys. They should be all
|
||||
numbers or all strings.
|
||||
|
||||
* lambda: number of keys per bucket when generating the g() function mapping.
|
||||
|
||||
* alpha: output hash space loading factor as percentage from
|
||||
1..100. 100% generates a *minimal* perfect hash function. But note that
|
||||
the implementation does *not* implement the necessary optimizations to
|
||||
ensure timely generation of minimal perfect hash functions. Normally you
|
||||
want a loading factor of 80% to 90% for large key sets.
|
||||
|
||||
* seed: random integer seed.
|
||||
|
||||
* nodiv: if true rounds r and m to powers of 2, and performs modular
|
||||
reduction using bitwise AND. Otherwise, r and m are rounded up to the
|
||||
nearest primes and modulo division used when indexing tables. Note that
|
||||
the rounding occurs after calculation of the intermediate and output hash
|
||||
table loading.
|
||||
|
||||
This is more important when building small hash tables with the C
|
||||
interface. The optimization is substantial when the compiler can inline
|
||||
the code, but isn't substantial from Lua.
|
||||
|
||||
Returns a callable object.
|
||||
|
||||
### phf:hash(key)
|
||||
|
||||
* Returns an integer hash in the range 1..phf:m(). The returned integer will
|
||||
be unique for all keys in the original set. Otherwise the result is
|
||||
unspecified.
|
||||
|
||||
### Example ###
|
||||
|
||||
```Lua
|
||||
local phf = require"phf"
|
||||
|
||||
local lambda = 4 -- how many keys per intermediate bucket
|
||||
local alpha = 80 -- output hash space loading in percentage.
|
||||
|
||||
local keys = { "apple", "banana", "cherry", "date", "eggplant", "fig",
|
||||
"guava", "honeydew", "jackfruit", "kiwi", "lemon", "mango" }
|
||||
|
||||
local F = phf.new(keys, lambda, alpha)
|
||||
|
||||
for i=1,#keys do
|
||||
print(keys[i], F(keys[i]))
|
||||
end
|
||||
|
||||
```
|
||||
|
||||
## C++ ##
|
||||
|
||||
## API ##
|
||||
|
||||
### PHF::uniq<T>(T k[], size_t n); ###
|
||||
|
||||
Similar to the shell command `sort | uniq`. Sorts, deduplicates, and shifts
|
||||
down the keys in the array k. Returns the number of unique keys, which will
|
||||
have been moved to the beginning of the array. If necessary do this before
|
||||
calling PHF::init, as PHF::init does not tolerate duplicate keys.
|
||||
|
||||
### int PHF::init<T, nodiv>(struct phf *f, const T k[], size_t n, size_t l, size_t a, phf_seed_t s);
|
||||
|
||||
Generate a perfect hash function for the n keys in array k and store the
|
||||
results in f. Returns a system error number on failure, or 0 on success. f
|
||||
is unmodified on failure.
|
||||
|
||||
### void PHF::destroy(struct phf *);
|
||||
|
||||
Deallocates internal tables, but not the struct object itself.
|
||||
|
||||
### void PHF::compact<T, nodiv>(struct phf *);
|
||||
|
||||
By default the displacement map is an array of uint32_t integers. This
|
||||
function will select the smallest type necessary to hold the largest
|
||||
displacement value and update the internal state accordingly. For a loading
|
||||
factor of 80% (0.8) in the output hash space, and displacement map loading
|
||||
factor of 4 (400%), the smallest primitive type will often be uint8_t.
|
||||
|
||||
### phf_hash_t PHF::hash<T>(struct phf *f, T k);
|
||||
|
||||
Returns an integer hash value, h, where 0 <= h < f->m. h will be unique for
|
||||
each unique key provided when generating the function. f->m will be larger
|
||||
than the number of unique keys and is based on the specified loading factor
|
||||
(alpha), rounded up to the nearest prime or nearest power of 2, depending on
|
||||
the mode of modular reduction selected. For example, for a loading factor of
|
||||
80% m will be 127: 100 is 80% of 125, and 127 is the closest prime greater
|
||||
than or equal to 125. With the nodiv option, m would be 128: 100 is 80% of
|
||||
125, and 128 is the closest power of 2 greater than or equal to 125.
|
||||
|
||||
## C ##
|
||||
|
||||
The C API is nearly identical to the C++ API, except the prefix is phf_
|
||||
instead of PHF::. phf_uniq, phf_init, and phf_hash are macros which utilize
|
||||
C11's _Generic or GCC's __builtin_types_compatible_p interfaces to overload
|
||||
the interfaces by key type. The explicit suffixes _uint32, _uint64, and
|
||||
_string may be used directly.

The default is to use the SSE1 version. If you define USE_SSE2 the

mother.

|
||||
The code is the exact rewriting of the cephes sinf function.
|
||||
Precision is excellent as long as x < 8192 (I did not bother to
|
||||
take into account the special handling they have for greater values
|
||||
-- it does not return garbage for arguments over 8192, though, but
|
||||
the extra precision is missing).
|
||||
|
||||
Note that it is such that sinf((float)M_PI) = 8.74e-8, which is the
|
||||
surprising but correct result.
|
||||
|
||||
Performance is also surprisingly good, 1.33 times faster than the
|
||||
macos vsinf SSE2 function, and 1.5 times faster than the
|
||||
__vrs4_sinf of amd's ACML (which is only available in 64 bits). Not
|
||||
too bad for an SSE1 function (with no special tuning) !
|
||||
However the latter libraries probably have a much better handling of NaN,
|
||||
Inf, denormalized and other special arguments..
|
||||
|
||||
On my core 1 duo, the execution of this function takes approximately 95 cycles.
|
||||
|
||||
From what I have observed on the experiments with Intel AMath lib, switching to an
|
||||
SSE2 version would improve the perf by only 10%.
|
||||
|
||||
Since it is based on SSE intrinsics, it has to be compiled at -O2 to
|
||||
deliver full speed.

* in different option sets to be defined.
|

*

* The alias option has to be first defined using cli.add<T>(). Defining
|
||||
* multiple aliases for the same option name but with different values is allowed.
|

*
|
||||
* As aliases are key-value pairs by default, values are compared as std::string.
|
||||
* If the command line option corresponding to the alias is a vector, the alias
