    acml_mp doesn't do threading (gfortran 4.2.2)

    apstc
      Edit: solved, it does go into multi-threading mode.

      ====

      I'm testing HPL (www.netlib.org/benchmark/hpl) with acml_mp 4.0.1.
      The version of gcc & gfortran is 4.2.2. Somehow, the HPL code doesn't
      execute in multi-threaded way even if I've properly set
      OMP_NUM_THREADS.

      The gfortran command is:
      gfortran -W -Wall -fopenmp -DAdd__ -DF77_INTEGER=int -DStringSunStyle -lacml_mp -lacml_mv ...

      To verify that my installation of gcc/gfortan is correct, I've successfully run
      an OpenMP-enabled Fortran code (but without using acml_mp).

      Any idea/pointer on how to track and fix this problem?
