Hi, I'm using gcc-4.9.0 and have a question OMP_DISPLAY_ENV. Is it possible to display which thread is bound to which core or is it planned to support such a thing in a later release of gcc? At the moment I don't get this information. linpc1 OpenMP 102 \gcc -fopenmp omp_default_env.c linpc1 OpenMP 103 setenv OMP_DISPLAY_ENV verbose linpc1 OpenMP 104 setenv OMP_PROC_BIND spread linpc1 OpenMP 105 setenv OMP_PLACES cores linpc1 OpenMP 106 a.out OPENMP DISPLAY ENVIRONMENT BEGIN _OPENMP = '201307' OMP_DYNAMIC = 'FALSE' OMP_NESTED = 'FALSE' OMP_NUM_THREADS = '4' OMP_SCHEDULE = 'DYNAMIC' OMP_PROC_BIND = 'SPREAD' OMP_PLACES = '{0},{1},{2},{3}' OMP_STACKSIZE = '140301846657264' OMP_WAIT_POLICY = 'PASSIVE' OMP_THREAD_LIMIT = '4294967295' OMP_MAX_ACTIVE_LEVELS = '2147483647' OMP_CANCELLATION = 'FALSE' OMP_DEFAULT_DEVICE = '0' GOMP_CPU_AFFINITY = '' GOMP_STACKSIZE = '140301846657264' GOMP_SPINCOUNT = '300000' OPENMP DISPLAY ENVIRONMENT END _OPENMP = 201307 omp_num_procs = 4 omp_num_threads = 4 omp_max_threads = 4 omp_dynamic = false omp_nested = false omp_level = 1 omp_active_level = 1 omp_max_active_level = 2147483647 omp_thread_limit = 2147483647 omp_schedule = dynamic,1 omp_cancellation = false omp_default_device = 0 omp_num_devices = 0 omp_num_teams = 1 omp_team_num = 0 omp_proc_bind = spread linpc1 OpenMP 107 Thank you very much for any answer in advance.
