I came across this error while running some of the spec CPU 2017 benchmarks. I encountered this error in cactuBSSN_s, lbm_s, and imagick_s (all of them are fpspeed benchmarks). Does the host system generate this error because of resource limitation or is it coming from gem5? I found this post in stack overflow https://stackoverflow.com/questions/53351194/openmp-libgomp-thread-creation-failed-resource-temporarily-unavailable-when, the solution suggested here to export OMP_NUM_THREADS=1 didn't work. Any help would be appreciated Madan
