I tried replacing the call to mpirun with mpiexec.hydra and it seems to work successfully as before. Please find below the contents of *.sh.o#### file corresponding to the Hello, World! run spanning more than one compute node:

The PE used for this purpose is called mpich_unstaged (basically, a copy of the original mpich with '$fill_up' rule). The only other PE in this system is called mpich_staged (a copy of the original mpich with '$pe_slots' rule). | | | | I have no clue what mpich_(un)staged refers to, I assume it's some setting from ROCKS.

I ensured the extend-*.xml files had no error in them using the xmllint command before rebuilding the distribution. All six compute nodes installed successfully, and so did running several test "Hello, World!" cases up to 72 cores. I can SSH into any one of these nodes, and SSH between any two compute nodes just fine. | | > | > | | > | > As of this morning all submitted jobs that require more than 12 cores (i.e., spanning more than one compute node) fail about a minute after starting successfully. However, all jobs with 12 or less cores within the a given compute node run just fine. The error message for failed job is as follows: | | > | > | | > | > error: got no connection within 60 seconds.

The line corresponding to the failed job from /opt/gridengine/default/spool/qmaster/messages is as follows: | | > | > | | > | > 12/16/2015 11:15:36|worker|athena|E|tightly integrated parallel task 6129.1 task 1.compute-0-1 failed - killing job | | > | > | | > | > I'd appreciate any insight or help to resolve this issue.

IIRC a tight integration was not supported before this one, as there was no call to `qrsh` automatically set up as you would need to start certain daemons beforehand. | | > | | | > | Does your version still need mpdboot? | | > | | | > | Do you request a proper set up PE in your job submission? | | > | | | > | -- Reuti | | > | | | > | > | | > | > Thank you for your time and help. | | > | > | | > | > Best regards, | | > | > g | | > | > | | > | > -- | | > | > Gowtham, PhD | | > | > Director of Research Computing, IT | | > | > Adj.
