This is the way I typically submit batch jobs:
qsub -l select=1:ncpus=40 rl-myjob
Ever since the Memorial Day weekend maintenance, jobs submitted this way have been running about 5 times slower than than they do on the login node. I traced the problem to ncpus values greater than 32. For example, on a small test that uses 64 threads and normally runs in under 30 seconds:
qsub -l select=1:ncpus=32 rl-myjob
# Finishes in about 24 seconds
qsub -l select=1:ncpus=33 rl-myjob
# Takes over 120 seconds
