[Swift-user] Question about nr of nodes

[Glen Hocky]

What I used to use was (shell variables should be self explanatory). This
should limit your number of nodes to $nodes while putting 1 coaster on each
one to run your jobs...
Things may have changed in the last few months and this might not work
correctly any more...

    <profile key="jobsPerNode" namespace="globus">24</profile>
    <profile namespace="globus"
key="providerAttributes">pbs.aprun;pbs.mpp;depth=24</profile>

    <profile namespace="env" key="OMP_NUM_THREADS">$PPN</profile>
    <profile namespace="globus" key="maxwalltime">$TIME</profile>
    <profile namespace="globus" key="maxTime">$MAXTIME</profile>
    <profile namespace="globus" key="slots">$nodes</profile>
    <profile namespace="globus" key="nodeGranularity">1</profile>
    <profile namespace="globus" key="maxNodes">1</profile>
    <profile namespace="globus" key="lowOverAllocation">100</profile>
    <profile namespace="globus" key="highOverAllocation">100</profile>
    <profile namespace="karajan" key="jobThrottle">200.00</profile>
    <profile namespace="karajan" key="initialScore">10000</profile>
