In case other projects may use these header files, we added
them into API/Internals.
* ComputationGraphAlgorithms.h was moved from Source/ComputationNetworkLib
* PrimitiveOpType.h and EvaluatorWrapper.h were moved from Source/CNTKv2Library
* PrimitiveFunctionAttribute.h was extracted from PrimitiveFunction.h. It contains
a new class PrimitiveFunctionAttribute which is the collection of all attribute
names for PrimitiveFunction.
This change actually had a subtle side-effect. We had a global static variable
s_stateAttributes that depended on PrimitiveFunction::AttributeNameRngSeed and
PrimitiveFunction::AttributeNameRngOffset. After we moved those static
attribute-variables into another translation unit, s_stateAttributes can be
initialized with empty wstring, because PrimitiveFunctionAttribute::AttributeNameRngSeed
PrimitiveFunctionAttribute::AttributeNameRngSeedOffset were initialized after
s_stateAttributes. Note that the initialization order of global static variables
is not well-defined cross translation units. To fix the issue, we also moved
s_stateAttributes into PrimitiveFunctionAttribute class, and renamed it to
s_rngStateAttributes. I think it's reasonable to consider s_rngStateAttributes
to be part of the PrimitiveFunctionAttribute class.
* PrimitiveFunction.h was moved from Source/CNTKv2Library

Sequential convolution v2.
* re-designed ConvolutionSequenceShapeNode: refactored to separate out computing output sequence length from v1 node design. And refactored ConvolutionNodeBaseExtended as their common base class. (Since "ConvolutionNodeBase" is not only base class of ConvolutionNode but also PoolingNode).
* Performance increase against v1.

set the multiverso lib file when asgd is set to true, otherwise it will
look for a lib that doesn't match any rule when asgd=false
We used to set CXX to mpic++, which was then used for building
Multiverso. Unfortunately, this kind of configuration conflicted
with find_package(MPI), and hence caused failure.
This commit fixed the issue by using system CXX for building
Multiverso. It also fixed two other issues:
* EVAL_LIB depends on libmultiverso, so we had to set
MULTIVERSO_LIB before the EVAL_LIB rule
* cmake variable doesn't have a "PATHNAME" type, we used
PATH instead. We also replace FILEPATH with PATH because
BOOST_LIBRARY_DIRS points to a path rather than a file.
Allow to add some extra cxxflags via system env.
Use cases:
1) https://github.com/Microsoft/CNTK/issues/3155
export CXXFLAGS="-Wno-unused-variable -Wno-sign-compare"
configure && make
2) Our libc/libstdc has been built with gcc-4.9. So we fail to build cntk in current state with gcc-5 in compatibility mode.
https://gcc.gnu.org/onlinedocs/libstdc++/manual/using_dual_abi.html
After patching cntk we have successful build:
COMMON_FLAGS="-D_GLIBCXX_USE_CXX11_ABI=0" CXXFLAGS="-D_GLIBCXX_USE_CXX11_ABI=0 -Wno-unused-variable -Wno-sign-compare" configure && make
(nvcc don't recongnise -W flags)
Thanks to Frank's initial code change.
Initialize NCCL with GPU ID frm nvml call instead of from device id in
/proc. Previous way causes "same device being used" error if two
different containers running on same host and try to initialize NCCL.
Add nvml library for nvml apis
Update the Makefile
In MKL-DNN 0.12 release, there's a cache size detection issue causing crash on AMD Ryzen CPUs.
This change disables MKL-DNN to unblock AMD Ryzen users for now.
This will help to build CNTK for nighlty builds with required CNTK
version. If environment variable 'BUILD_CNTK_VERSION' is set, then CNTK
will be build for that version as a public release('+' won't be appended
to CNTK version). Otherwise hard-coded CNTK version will be used as a
private build (2.4+).
- Accelerates some common tensor ops in Intel CPU inference for float32, especially for fully connected networks
- Can be turned on/off by cntk.cntk_py.enable_cpueval_optimization()/cntk.cntk_py.disable_cpueval_optimization()
CNTK now supports CUDA 9/cuDNN 7. This requires an update to build environment to Ubuntu 16/GCC 5 for Linux, and Visual Studio 2017/VCTools 14.11 for Windows. With CUDA 9, CNTK also added a preview for 16-bit floating point (a.k.a FP16) computation.
Please check out the example of FP16 in ResNet50 at /Examples/Image/Classification/ResNet/Python/TrainResNet_ImageNet_Distributed.py
Notes on FP16 preview:
* FP16 implementation on CPU is not optimized, and it's not supposed to be used in CPU inference directly. User needs to convert the model to 32-bit floating point before running on CPU.
* Loss/Criterion for FP16 training needs to be 32bit for accumulation without overflow, using cast function. Please check the example above.
* Readers do not have FP16 output unless using numpy to feed data, cast from FP32 to FP16 is needed. Please check the example above.
* FP16 gradient aggregation is currently only implemented on GPU using NCCL2. Distributed training with FP16 with MPI is not supported.
* FP16 math is a subset of current FP32 implementation. Some model may get Feature Not Implemented exception using FP16.
* FP16 is currently not supported in BrainScript. Please use Python for FP16.
To setup build and runtime environment on Windows:
* Install [Visual Studio 2017](https://www.visualstudio.com/downloads/) with following workloads and components. From command line (use Community version installer as example):
vs_community.exe --add Microsoft.VisualStudio.Workload.NativeDesktop --add Microsoft.VisualStudio.Workload.ManagedDesktop --add Microsoft.VisualStudio.Workload.Universal --add Microsoft.Component.PythonTools --add Microsoft.VisualStudio.Component.VC.Tools.14.11
* Install [NVidia CUDA 9](https://developer.nvidia.com/cuda-90-download-archive?target_os=Windows&target_arch=x86_64)
* From PowerShell, run:
/Tools/devInstall/Windows/DevInstall.ps1
* Start VCTools 14.11 command line, run:
cmd /k "%VS2017INSTALLDIR%\VC\Auxiliary\Build\vcvarsall.bat" x64 --vcvars_ver=14.11
* Open /CNTK.sln from the VCTools 14.11 command line. Note that starting CNTK.sln other than VCTools 14.11 command line, would causes CUDA 9 [build error](https://developercommunity.visualstudio.com/content/problem/163758/vs-2017-155-doesnt-support-cuda-9.html).
To setup build and runtime environment on Linux using docker, please build Unbuntu 16.04 docker image using Dockerfiles /Tools/docker. For other Linux systems, please refer to the Dockerfiles to setup dependent libraries for CNTK.

Remove OpenCV dependency from CNTK core
Tensorboard's Image feature has a hard dependency on OpenCV and
Tensorboard is a part of CNTK core. Removing this hard dependency
by creating a new DLL ImageWriter just to write an image an PNG.
On Linux:
sudo mkdir /usr/local/mklml
sudo wget https://github.com/01org/mkl-dnn/releases/download/v0.11/mklml_lnx_2018.0.1.20171007.tgz
sudo tar -xzf mklml_lnx_2018.0.1.20171007.tgz -C /usr/local/mklml
On Windows:
Create a directory on your machine to hold MKLML, e.g. mkdir c:\local\mklml
Download the file [mklml_win_2018.0.1.20171007.zip](https://github.com/01org/mkl-dnn/releases/download/v0.11/mklml_win_2018.0.1.20171007.zip).
Unzip it into your MKLML path, creating a versioned sub directory within.
Set the environment variable `MKLML_PATH` to the versioned sub directory, e.g. setx MKLML_PATH c:\local\mklml\mklml_win_2018.0.1.20171007
This change also enables CPU convolution forward/backward using MKL, which leads to ~4x speedup in AlexNet training.
