Title: starting with mpirun but using only 1 proc. Post by paulfg on Dec 7th, 2006 at 9:10am
hello,
i have a working cluster, other MPI soft runs correctly, and i use lam. i compiled with "build.sh MPI" i tried to run "mpirun -np 60 /...path.../HYPHYMPI filename.cfg" it seems to work correctly, but using only 1 proc on the master node. do you have any ideas ? i've probably done something wrong during compilation thanks, paul. |

Dear Paul,
HyPhy does not automatically (in general) distribute the code across nodes (especially if you have a custom file). Many standard analyses do, however, contain code needed to work in an MPI environment. Also, there are command line flags which will distribute certain analyses across MPI nodes. Try $mpirun -np xx ./HYPHYMPI BatchFiles/MPITest.bf for a very simple diagnostic to make sure HyPhy runs on your cluster properly. If you can tell me what you are trying to to, I can help you out. Cheers, Sergei |

hi
thanks, the mpi test works ! i think i have to go back to the script author to ask how they run it with mpi usually. ------- Running a HYPHY-MPI test Detected 10 computational nodes Polling slave nodes...
