[mpich-discuss] ask for help

[Zhengqiang Ma]

HI, I had a cluster comprising 12 Apple dual quad-core 2.26-GHz Mac Pros (each with 6GB of RAM) connected to a single quad-core 2.26-GHz Mac Pro as the head node (with 6GB of RAM). Recently when I add another 2GB memory to each of the member nodes and 10GB to the head node, I can no longer run mpi jobs. I keep getting the error like:

rank 0 in job 1  node00x.cluster.private_xxxxx   caused collective abort of all ranks

exit status of rank 0: return code 255

Job management is handled by the Sun Grid Engine (SGE) package from Sun MicroSystems, and the iNquiry Suite from the BioTeam.


Please help.


Thank you very much.
