[torqueusers] pbs_mom disk space check

Dear all,

it seems that the answer to the question is easier than I thought. The idea behind the â-l fileâ option in qsub seems to mean that each single process gets a reservation of the local disk space requested. In our case the job didnÂŽt start, because we used âppn=8â and â-l file=35500gbâ. The /scratch dir had a free space of 270TB and therefore the behavior was correct.

Best regards,
Henrik

Dear all,
we are using torque-4.2.7 and I observed a problem with the '-l fileâ option in qsub in combination with the âsize [=/scratch]â option in mom_priv/config.
Whenever a job requests more than 32TB, the job does not start. Of course the disk space in our /scratch is large enough (270TB currently).
Is there a limit for the disk space check? And why is it in the range of 2^35?
Any hints?
Thanks!
Henrik
