User Information Home
 NCSA's Help Desk is available 24 hours a day, seven days a week, 365 days a year: June 29, 2007 Dear NCSA User Community: Following an extended installation and Friendly User period for the NCSA's Dell PowerEdge 1955 Blade Server Cluster, dubbed "abe", NCSA will be moving the resource into production mode on July 9, 2007. The Friendly User period has been very useful in sorting out the issues with setting up and configuring the environment, and a number of the Friendly Users have been quite successful in bringing their applications up and optimizing them. NCSA staff have been working to bring the cluster to a production state and we look forward to the system being a useful addition to the available resources. In order to have access beyond July 9, 2007, those with current Friendly User projects will need to either have a peer-reviewed allocation or request a Development Allocation project on the system. For information on getting allocations see: Access to the abe blade server cluster will be discontinued at 12:00am July 9, 2007. At that point in time the system will have all final preparations to move into production mode including the removal of all Friendly User accounts and the establishment of all accounts associated with projects for production mode. The system will again become available before the end of the day on July 9. Since this resource is intended to provide an evolutionary path for users of tungsten, NCSA's Dell PowerEdge 1750 cluster, we would like to encourage those with current allocations on tungsten that can meet the use policies for abe (namely, to regularly run applications at 1,000 cores or more), to transfer all or part of their remaining tungsten allocations to abe. A favorable conversion rate of 1.5:1 for tungsten to abe SUs is available through August 31, 2007 for current tungsten allocations. To request transfers of allocations to abe, please contact the NCSA Allocations staff at allocations@ncsa.uiuc.edu. In that email indicate the project principal investigator, the project PSN (three letter project code), and whether you wish to transfer all the tungsten service units or only a partial number of the service units (list how many SUs.) The production environment on abe will consist of 1200 compute blade nodes each configured as follows:
8 GBytes RAM 1 InfiniBand (IB) interface All the nodes have shared access to a 100TByte filesystem (Lustre filesystem). More details regarding the abe cluster at NCSA are available at: If you should have any questions, please feel free to direct them to me, John Towns by phone at 217-244-3228 or by email at jtowns@ncsa.uiuc.edu or to the NCSA Consulting Office, consult@ncsa.uiuc.edu (217-244-1144). Regards,John Towns |
