When I last set up SGE at some place (~ 2008) I used NFS to share the
home directory file system between the batch server and the nodes. Hence
no prolog/epilog arrangements were needed. If this is not the case, then
yes, files have to be somehow transferred in before and taken out after
the job runs on the node.
BTW: Some of the errors in the gridFTP log files implicated
.gahp_complete - a signal file to show when an operation is done. I
think Gahp utilises file transfer protocols such as SSH and FTP to work.
So perhaps the problem does lie in the transfer of input files. To
check, somehow snatch the failing job specification file (that ARC
produces) before it gets sent to the SGE server, and try submitting that
by hand. If it fails, that will show why the batch system is not
receiving or accepting the work.
Cheers,
