MPI programs using certain debug options have a long startup time. This was traced to a "vmalloc/vfree" in the code that reads /proc/sgi_sn/sn_topology. On large systems, vfree requires an IPI to all cpus to do TLB purging. Replace the vmalloc/vfree with kmalloc/kfree. Although the size of the structure being allocated is unknown, it will not not exceed 96 bytes. Signed-off-by: Jack Steiner <steiner@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com> |
