That's what I thought, too, but I can't find anything that it could be
requesting that can't be satisfied. It's only running on 4 processors,
and I can run other jobs, it's only this one that uses DRMAA that hangs.
I should point out that the job starts to run, then fails when the DRMAA
is invoked. Here's the jobscript I'm submitting:
#!/bin/bash
#$ -V
#$ -cwd
#$ -m abe
#$ -l h_rt=00:10:00
#$ -R y
export
CLASSPATH=/usr/local/share/sge/lib/drmaa.jar:/usr/local/share/sge/lib/jgd
i.jar:/usr/local/share/sge/lib/juti.jar
export LD_LIBRARY_PATH=/usr/local/share/sge/lib/lx24-amd64
/usr/local/share/bin/math < factor.m
And here's the Mathematica file:
Needs["ClusterIntegration`"]
kernels = LaunchKernels[SGE["aurora.sns.ias.edu"], 4]
ParallelMap[FactorInteger, (10^Range[20, 30] - 1)/9]
CloseKernels[]
And here's more of the output:
Mathematica 7.0 for Linux x86 (64-bit)

... the rest is just the answer...
So the problem seems to lie somewhere in the DRMAA invocation. How can I
debug/troubleshoot this? The job doesn't run long enough to do a qstat
-j <jobid>, and I wonder if that would give me anything useful in this
case.
Are there any special configuration you need to enable DRMAA in SGE? I
don't remember evrer setting anything, and this exact program has been
working without a single hiccup for over a year, but it could be that I
accidently changed a setting.
