I am relatively new to OpenMPI and Sun Grid Engine parallel integration. I have a small cluster that is running SGE6.2 on linux machines all using Intel Xeon processors. I have installed OpenMPI 1.2.7 from source using the --with-sge switch. Now, I am trying to troubleshoot some problems I am having. I have created a simple job script:
The job script looks like: #!/bin/bash #$ -S /bin/bash #$ -cwd mpirun --mca pls_gridengine_verbose 1 -np $NSLOTS hostname And the output on the error stream: > more junksub.sh.e3574 [shakespeare:05720] mca: base: component_find: unable to open ras tm: file not found (ignored) [shakespeare:05720] mca: base: component_find: unable to open pls tm: file not found (ignored) Starting server daemon at host "shakespeare.nci.nih.gov" Starting server daemon at host "octopus.nci.nih.gov" Server daemon successfully started with task id "1.shakespeare" [shakespeare:05733] mca: base: component_find: unable to open ras tm: file not found (ignored) [shakespeare:05733] mca: base: component_find: unable to open pls tm: file not found (ignored) error: executing task of job 3576 failed: failed sending task to ex...@octopus.nci.nih.gov: can't find connecti on [shakespeare:05720] ERROR: A daemon on node octopus.nci.nih.gov failed to start as expected. [shakespeare:05720] ERROR: There may be more information available from [shakespeare:05720] ERROR: the 'qstat -t' command on the Grid Engine tasks. [shakespeare:05720] ERROR: If the problem persists, please restart the [shakespeare:05720] ERROR: Grid Engine PE job [shakespeare:05720] ERROR: The daemon exited unexpectedly with status 1. However, there is no output in any output stream. And if I log into shakespeare and qrsh -q all.q@octopus, I immediately get a slot, so there isn't a "direct" problem with connecting. As I got a hint from folks on the SGE mailing list, it appears that qrsh is not being used for job submission. Any suggestions as to why this might be the case (or if it is the case)? Thanks, Sean
