--- Comment #22 from edison <edison_chan_gz at hotmail dot com> ---
for 607.cactuBSSN_s,if use preENV_GOMP_CPU_AFFINITY = 0-23 in CPU2017 .cfg, all
p-core(i9-13900k) usage will down to 15%(the e-core almost 100%), if comment
out it all p-core usage will up to 60%.
607.cactuBSSN_s on i9-13900K
gcc 14.1
preENV_GOMP_CPU_AFFINITY = 0-23： 60.1 (-41.7 % slower)
# preENV_GOMP_CPU_AFFINITY = 0-23： 103
but for AMD Zen4(+) that maybe another story so far(AMD Zen4 need
preENV_GOMP_CPU_AFFINITY to make the threads run on high performance core
first).
