Tested with libgomp testsuite and looked at performance numbers of Sho's omp_fib.c and libgomp.c/sort-1.c, unfortunately the differences looked to be in the noise. But, e.g. on omp_fib.c strace -f shows that the number of futex FUTEX_WAKE syscalls went down a lot (from ~ 75000 for omp_fib 32 down to ~ 50 with the default wait policy, of course for OMP_WAIT_POLICY=passive it remained roughly the same).
I have tested the patch on an Intel(R) Xeon(R) CPU X5570 @ 2.93GHz (2x Quad with hypherthreading) with SUSE Linux Enterprise Server 11 (x86_64), PATCHLEVEL = 1 and GNU C Library stable release version 2.11.1.
GCC 4.7.0 20110714 [trunk revision 176260] flags: -Ofast -march=native -funroll-loops -flto -fwhole-program
Tested with four programs (in different variations) of NANOS's OpenMP task (!) test suite, available at http://nanos.ac.upc.edu/content/barcelona-openmp-task-suite
I always did 3 runs with the original libgomp.so and three with the patched one, taking the average of those runs. The columns are: Average run time (old), relative speed up to serial version, average run time (patched), speedup to the serial version, ratio (old)/(patched) in per cent.
Thus, the per-cent number is the crucial number - and the higher the better for this patch.
FFT and health profit a lot from the patch - especially for with many threads; alignment is in the noise. Taking the % number, summing it up and dividing it by the number of runs gives: 102.2%, which indicates a ~2% performance gain.
Thanks for the patch Jakub! Tobias PS: I have repeated the FFT test cases to see how reliable the numbers are.
