I have a short test job that I can submit to different
queues on my cluster that appear to be configured the
same, but I get different results. Here is the job:
-------------------------------------------
#!/bin/tcsh
#
#$ -N show-limits
#$ -S /bin/tcsh
#$ -o show-limits.out
#$ -e show-limits.err
#$ -m ae
#$ -pe mpich 32
/bin/echo I am running on host `hostname`.
/bin/echo Original limits:
limit
/bin/echo
/bin/echo limit descriptors 65535
limit descriptors 65535
/bin/echo
/bin/echo New limits:
limit
-------------------------------------------
If I submit the job to all.q, it works and I get output
like this:
I am running on host compute-1-51.local.
Original limits:
cputime unlimited
filesize unlimited
datasize unlimited
stacksize unlimited
coredumpsize 0 kbytes
memoryuse unlimited
vmemoryuse unlimited
descriptors 40960
memorylocked 32 kbytes
maxproc 81920
limit descriptors 65535
New limits:
cputime unlimited
filesize unlimited
datasize unlimited
stacksize unlimited
coredumpsize 0 kbytes
memoryuse unlimited
vmemoryuse unlimited
descriptors 65535
memorylocked 32 kbytes
maxproc 81920
If I submit the same job to the queue xyz-nodes, I get output
like this:
I am running on host compute-0-19.local.
Original limits:
cputime unlimited
filesize unlimited
datasize unlimited
stacksize unlimited
coredumpsize 0 kbytes
memoryuse unlimited
vmemoryuse unlimited
descriptors 1024
memorylocked 32 kbytes
maxproc 524288
limit descriptors 65535
limit: descriptors: Can't set limit
Notice that the default descriptors limit is different, and
under all.q, I can change it, but under xyz-nodes, I can't.
I have carefully compared the queue configurations with
'qconf -sc all.q' and 'qconf -sc xyz-nodes' and I do not see any
difference, so I don't understand why I get different behavior
from the two queues.
Any ideas?
