Re: [condor-users] controlling number of jobs running at once

[Henry Knowles <Henry.Knowles@xxxxxxxxxxxxx>]

hi,

i've had this problem too.  you can set the number of jobs 
running using

MAX_JOBS_RUNNING	10

you might also find that if there is a delay between starting jobs that
it might help:

JOB_START_DELAY		5

which is the time in seconds.  both these want to go into 
condor_config.local, and then you need to issue a condor_reconfig.  The
other option is to copy the data onto a number of machines, and then 
just use them.

hope that helps,
henry
