Bioinformatics Computing Consultant Position Available

October 31, 2011 by Katie Antypas | 0 Comments

NERSC and the Joint Genome Institute (JGI) are searching for two individuals who can help biologists exploit advanced computing platforms. JGI provides production sequencing and genomics for the Department of Energy. These activities are critical to the DOE missions in areas related to clean energy generation and environmental characterization and cleanup. JGI has recently partnered with NERSC, the DOE Office of Science’s flagship computing center, a world leader in providing high-performance computing tools and expertise that enable computational science of scale. This partnership gives JGI staff access to supercomputer class systems, advanced architectures, and large-scale storage systems enabling JGI to address the most demanding genomic problems. This position will help bridge the gap from biology to computational science. The position will support the JGI mission by directly engaging with biologists to assist them with effectively using the range of computational resources at their disposal. 

You can read more about the positions and apply at Bioinformatics High Performance Computing Consultant (job number: 73194) and Software Developer for High Performance Computing Bioinformatics (job number: 73396).

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:
