I assume that both of them are quite computationally intensive since they have mpi support. The question is: which one of the libraries should I compile with mpi support, given that they will be used with mpb? ps: thanks for helping me solve the previous problems. -- "Because while the truncheon may be used in lieu of conversation, words will always retain their power.
