Hi all, Good morning!
I have trouble to communicate through sm btl in open MPI, please check the attached file for my system information. I am using open MPI 1.4.3, intel compilers V11.1, on linux RHEL 5.4 with kernel 2.6. The tests are the following: (1) if I specify the btl to mpirun by "--mca btl self,sm,openib", if I did not specify any of my computing nodes twice or more in the node list, my job runs fine. However, if I specify any of the computing nodes twice or more in the node list, it will hang there forever. (2) if I did not specify the sm btl to mpirun as "--mca btl self,openib", I could run my job smoothly, either put any of the computing nodes twice or more in the node list, or not. >From above 2 tests, apparently something wrong with sm btl interface on my system. As I checked the user archive, sm btl issue has been encountered due to the comm_spawned parent/child processes. But this seems not the case here, if I do not use any of my MPI based solver, only with MPI initialization and finalization procedures called, it still has this issue. Any comments? Thanks, Yiguang
