User Information Home
 NCSA's Help Desk is available 24 hours a day, seven days a week, 365 days a year: July 1, 2008 Dear colleagues: On July 21, 2008 the Dell PowerEdge 1750 cluster at NCSA, known as Tungsten, will be retired after more than 4 years of highly productive computational service. This notice is to inform you of the details surrounding the final shutdown of Tungsten. First and foremost, we want you to be aware that all remaining machine specific allocations, by default, will be transferred to NCSA's Dell cluster known as Abe. The transfer rate will be to the users benefit at a one to one ratio. Information on the system is available on our hardware page at: http://www.ncsa.uiuc.edu/UserInfo/Resources/Hardware/Intel64Cluster/. The unused balance of machine specific MRAC/LRAC and NCSA DAC allocations on Tungsten will be transferred to Abe at a ratio of 1 to 1 by default. Transfer of remaining allocation to another NCSA/TeraGrid resource is available, at the request of the project's Principal Investigator (PI). These requests will only be approved if resources are available and appropriate on the system to which the PI desires to transfer their balance. These allocations will expire on their original expiration date. All requests for transfers, other than the default to Abe, should be sent to the Allocations department at allocations@ncsa.uiuc.edu . The request must list the project's Principal Investigator, the project PSN, the amount of SUs to be transferred, and the machine to which transfer will be made by July 15, 2008 in order to guarantee that the transfer will be made before the account is moved to Abe. Abe will also become part of the TeraGrid roaming resources as of July 1, 2008. If you are an existing TeraGrid roaming account user and you can utilize Abe, please send email to allocations@ncsa.uiuc.edu requesting your roaming project be added. All user processes on Tungsten will be terminated at 11:59 PM, July 20, 2008. After this time, user access will be denied to tungsten.ncsa.uiuc.edu and all batch hosts. The home directories of Tungsten will be mounted on the head nodes of Abe till August 31, 2008 to ease the transition. Users who have data in the projects directory will be contacted to determine individual needs. Data remaining in the scratch directories will not be moved to another resource. At this time, it is our intention to move all applications software supported on Tungsten over to Abe. If there are unforeseen issues, we will contact the users with dependencies on those codes. If you require assistance in migrating your codes or data, please contact the HPC Consulting Office at 217-244-1144 or by e-mail at consult@ncsa.uiuc.edu. If you have questions or concerns, please contact Mike Pflugmacher, Assistant Director of Computing and Data Management, by phone at 217-244-1337 or by email at mikep@ncsa.uiuc.edu. Thank you, Mike Pflugmacher |
