question to OMP_DISPLAY_ENV

[Siegmar Gross]

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

Thank you very much for any answer in advance.


Kind regards
