Volume 5, Number 2 Redwood Upgraded to 224 CPUs During the week-long outage from June 21 to June 29, MCSR upgraded Redwood, your SGI 3700 capability resource supercomputer, from 192 to 224 processors, and from 192 GB to 224 GB of memory. This upgrade was made possible in part by infrastructure money from a grant received from the EPSCoR-related NSF Research Infrastructure Improvement Program, the result of a collaborative proposal with Dr. Greg Tschumper in the UM Chemistry and Biochemistry Department. The hardware was purchased from James River Technical, Inc., and installed by SGI engineers from Hunstsville, AL and Vicksburg, MS. Our thanks go out to Greg Tschumper and our partners at SGI and James River, for helping to make this upgrade possible and successful.The additional 32 Itanium2 1.3 GHz processors have been added to the general 1.3 GHz processor pool of the various queues (Red-4, Red-8, Red-16, etc.) in the 2nd PBS instance on redwood. For more information on the current MCSR PBS queue structure, see our online PBS tutorial. . We are pleased that we were able to retain the queue status of user PBS jobs that were running or queued before the upgrade, and all restarted jobs seem to be accumulating CPU time since the return of redwood to service. However, please pay attention to your jobs' progress over the next few days, and let us know if you think your job is languishing for any reason. Redwood continues to be the most in-demand of MCSR's systems, but we hope that the additional 32 processors will lead to a decline in queue wait times over the coming weeks. As a reminder, you can view hourly status of all running (but not queued) jobs on MCSR systems online from the MyMCSR portal of the MCSR Website.
