Hi,
I agree with your assessment of the usefulness of -binding. For that reason (and
others) we haven't bothered with it.
Although not optimal (for optimal, ask for all cores), we simply allocate ncores
from an undifferentiated pool (which may be a subset of all cores) that is
associated with a h

Hi,
Yes, cpu == core. The legacy naming is somewhat unfortunate. I'll update
the page to clarify.
The 1 slot - 1 core approach does not work for us because:
* each task may use more than one core (e.g., openmp, multithread)
* specifying ncpus allows for grouping that better matches the applicatio

Hi,
When gridengine calculates cpu usage (based on wallclock) it uses:
cpu usage = wallclock * nslots
This does not account for the number of cpus that may be used for
each slot, which is problematic.
