[Swift-user] [SWIFT JOBS]How To Efficiently Set Sites.xml

[Michael Wilde]

And also, Weiyang: 



Your sites.xml entry says "provider=pbs". That does not work on Beagle. In fact, it causes jobs to run on the login node. (Note to Swift developers: we should prevent this from happening by accident). 


change execution provider="pbs" to execution provider="coaster" 
in the line <execution provider="pbs" url="none" jobManager="local:pbs"/> 


I did not check the rest of your sites file. 


Ketan, can you point Wei to the Beagle Swift instructions? 


Thanks, 

- Mike

Hi Weiyang, 

Ideally workerspernode and ppn should be 24 on beagle to reflect 24 cores per node. 

That should make maximum utilization of a node.

Hello, 


Currently my submitted SWIFT jobs are seemed run single-thread, while my sites.xml is like 



<config> 
<pool handle="pbs"> 
<execution provider="pbs" url="none" jobManager="local:pbs"/> 
<profile namespace="globus" key="maxwalltime">0:20:00</profile> 
<profile namespace="globus" key="workersPerNode">8</profile> 
<profile namespace="globus" key="ppn">8</profile> 
<!-- <profile namespace="globus" key="internalHostname">172.5.86.6</profile>--> 
<profile namespace="globus" key="nodeGranularity">1</profile> 
<profile namespace="globus" key="maxNodes">5</profile> 
<profile namespace="karajan" key="jobThrottle">1.99</profile> 
<profile namespace="karajan" key="initialScore">10000</profile> 
<profile namespace="globus" key="project">CI-SES000031</profile> 
<!--gridftp url="local://localhost" />--> 
<filesystem provider="local"/> 
<!--scratch>/home/frankwang/tmp</scratch>--> 
<workdirectory>/lustre/beagle/scratch</workdirectory> 
</pool> 
</config> 


Do any of you have ideas to adjust it so that it'll be more efficient?
