[Trilinos-Users] using openmp in Trilinos

Hello,

I'm interested in running some Tpetra-based code on a cluster of multicore nodes.  I want to run one MPI process per node, with several threads per process using OpenMP.

I saw that to enable OpenMP in my code, I should add this to my configuration script:
  -D Trilinos_ENABLE_OpenMP:BOOL=ON

Should I also build with the multithreaded version of BLAS/LAPACK, or does that interfere with the OpenMP in Trilinos?

Thank you,
Alicia Klinvex
