Hi, I'm now debugging my MPI programs. The program crashes when a certain PML or BTLs are used (I guess).
For example, $ mpiexec ./prog # works $ mpiexec --mca btl openib ./prog # works $ mpiexec --mca btl openib,vader,self ./prog # crash $ mpiexec --mca pml ucx ./prog # works So, I would like to know if there is a way to show which PML/BTL components are ACTUALLY used at runtime. Of course, I can test these components one by one manually, it would be direct and efficient if Open MPI does it. Thanks! Keisuke -- FUKUDA, Keisuke <福田圭祐> Tokyo, Japan Email: keisukefuk...@gmail.com
