1) Questions and Answers : Getting started : Cluster startup: no more work units (Message 30761)

Hi all:

I\'m bringing a new computational cluster online, and I wanted to \"stress-test\" it by running boinc/climateprediction.net on it for a while. We have 128 processors on this cluster, so I just set it up to run climateprediction on all processors. It got up to about 37 before all of the remaining procesors are returning:

Fri 28 Sep 2007 11:26:22 AM PDT|climateprediction.net|Requesting 60480 seconds of new work
Fri 28 Sep 2007 11:26:27 AM PDT|climateprediction.net|Scheduler RPC succeeded [server version 509]
Fri 28 Sep 2007 11:26:27 AM PDT|climateprediction.net|Message from server: No work sent
Fri 28 Sep 2007 11:26:27 AM PDT|climateprediction.net|Deferring communication for 44 min 36 sec
Fri 28 Sep 2007 11:26:27 AM PDT|climateprediction.net|Reason: no work from project

My tests require that I fully load the cluster...what can I do? I have 4 nodes (8 cores/node) fully loaded, and a few more with only a single thread. Is there some setting I can set to allow more work units? Did I really empty the work unit queue for the project?

Thanks!

(This is for the Lab for Atmospheric Research when it goes fully online, so I thought it appropriate to test with climateprediction.net)
