Does anyone on here have experience configuring SGE to work with MATLAB's Distributed Computing Environment (MDCE)?
SGE is not natively supported by MATLAB, but can use their 'generic scheduler' facility. They provide all of the scripts needed, and even include a template for the PE. I've followed all the instructions, but when I try to submit a parallel job using the validation function of MATLAB's parallel configuration manager, it fails. Digging into the problem, it looks like MATLAB uses the first task to start an mpd daemon, because in the MATLAB logs I see this: Starting SMPD on node65 node66 ... ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null node65 "/usr/loc al/matlab/bin/mw_smpd" -s -phrase MATLAB -port 25955 Permission denied, please try again. Permission denied, please try again. Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password). Launching smpd failed for node: node65 Stopping SMPD on ... Exiting with code: 0 When I ssh into the node where the job is starting (node65) in this case, I run that command just fine. Both of these commands work: ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null node65 "/usr/local/matlab/bin/mw_smpd" -s -phrase MATLAB -port 25955 ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null node66 "/usr/local/matlab/bin/mw_smpd" -s -phrase MATLAB -port 25955 I suspect this is a problem with SGE not forwarding my SSH key, or something of that nature. I require a passphrase for my SSH key, so I suspect that might be the problem. Can anyone confirm or deny that? -- Prentice Bisbal Linux Software Support Specialist/System Administrator School of Natural Sciences Institute for Advanced Study Princeton, NJ _______________________________________________ users mailing list [email protected] https://gridengine.org/mailman/listinfo/users
