Re: [Condor-users] Running several jobs contemporary

[Alexander Lincoln Read <a.l.read@xxxxxxxxxx>]

Hi Nils,

This is from condor_config:

##  If you want to "lie" to Condor about how many CPUs your machine
##  has, you can use this setting to override Condor's automatic
##  computation.  If you modify this, you must restart the startd for
##  the change to take effect (a simple condor_reconfig will not do).
##  Please read the section on "condor_startd Configuration File
##  Macros" in the Condor Administrators Manual for a further
##  discussion of this setting.  Its use is not recommended.  This
##  must be an integer ("N" isn't a valid setting, that's just used to
##  represent the default).
#NUM_CPUS = N

You could try setting N (in the condor_config of the execute machine)
to something higher than the number of physical CPU's. But the more
jobs you allow to run concurrently the less efficient the total throughput
will be.

Cheers, Alex
