[Swift-user] control number of condor nodes?

[Glen Hocky]

Hey Everyone,
Quick question. I'm testing on bg/p and things are working fine, but I can't
seem to increase the number of nodes I'm using in the way I expect. I can
run fine on 64 nodes tih

     <filesystem provider="local"/>

    <execution provider="coaster" jobmanager="local:cobalt"/>

    <profile namespace="globus" key="queue">prod-devel</profile>

    <profile namespace="globus" key="slots">1</profile>

    <profile namespace="globus" key="nodeGranularity">64</profile>

    <profile namespace="globus" key="workersPerNode">4</profile>

    <profile namespace="globus" key="maxNodes">64</profile>

    <profile namespace="globus" key="project">OOPS</profile>

    <profile namespace="globus" key="kernelprofile">zeptoos</profile>

    <profile namespace="globus" key="maxtime">3559</profile>

    <profile namespace="globus" key="alcfbgpnat">true</profile>

    <profile namespace="karajan" key="jobThrottle">2.55</profile>

    <profile namespace="karajan" key="initialScore">100000</profile>

I successfully went up to 256 nodes by increasing slots to 4 but I was
unable to get a block of size 256.
When I set maxnodes to 256, slots=1 , i get a block of size 128 regardless
of several changes (and removal) of jobThrottle

Any ideas on how to fine tune this, because I will certainly need to choose
my number of jobs based on an expected ( max wall time * workers per node *
number of nodes )
