Serial and Westmere Queues on Carver

September 20, 2011 by Francesca Verdier | 0 Comments

NERSC has replaced 80 8-core Intel Nehalem nodes on Carver with 80 12-core Intel Westmere nodes. The new processors run at the same frequency as those they replace, but have slightly larger caches. Also, the Westmere nodes are populated with 48GB of memory; the memory runs at 1333MHz. This new hardware serves two purposes. First, it provides access to more memory (48GB) than is available on other Carver compute nodes (24GB). This capability is available through a new batch queue "westmere".  As an incentive to use the new westmere queue, its jobs will be charged for 8 cores, not the 12 cores that these nodes have.

Hopper Scaling Incentive Program

August 30, 2011 by Francesca Verdier | 0 Comments

For projects that haven't yet scaled their codes to 683 or more nodes (which is the level at which a job is considered "big" on hopper) NERSC is offering scaling incentives, mostly focused on the use of OpenMP.  For some codes, adding OpenMP directives will allow you to scale up and run bigger science problems.

For users accepted in the Scaling Incentive Program:

2012 NERSC allocation requests due September 23

August 17, 2011 by Francesca Verdier | 0 Comments

The ERCAP allocation submission system is now open for 2012 NERSC allocation requests. All current projects (including startup, education, and ALCC projects) must be renewed for 2012 if you wish to continue using NERSC.  New project requests may be submitted as well (for either the remainder of 2011 or for 2012).

The deadline for 2012 requests is September 23, 2011.

Award decisions for requests submitted before this deadline will be emailed to Principal Investigators and PI Proxies on December 14. Production requests made after September 23 will be reviewed in late January 2012. New startup requests awarded after June 2011 may be renewed for 2012 after the September 23 deadline.

2012 allocations will be for the period January 10, 2012, through January 7, 2013.
