I'd like to share results of stress testing ofIntel OpenMP library for a 32-bit platform:
Intel OMP Performance Library
version 5.0.20111219 for IA-32 architecture
built on 2011-12-19 17:12:07 UTC
A purpose of the stress test was as follows:
Create as many as possible OpenMP threads in a parallel region on aone CPU system.
It isstated by Intel that up to 16,384 OpenMP threads could be created in a parallel region. This is not true,
because a simpletest application easily created more than 18,600 OpenMP threads on a 32-bit Windows XP
operating system ( 4GB of Virtual Memory ).
How would I compare Intel OpenMP library with Microsoft OpenMP library?
Intel's library is far more advancedand demonstrated outstanding capabilities (!).Microsoft's library
doesn't allow to create more than 64 OpenMP threads in a parallel region. Intel's OpenMP library could be used
forsophisticated scientific projects that require a veryhigh level of parallelization.
