Los Alamos National Laboratory has a new high-performance computer system that will be used for unclassified research. Called Wolf, the machine has 616 compute nodes, each with two 8-core 2.6 GHz Intel Sandybridge processors, 64 GB of memory, and a high-speed Infiniband interconnect network.
The recently installed computing system, manufactured by Cray, utilizes Los Alamos' existing Panasas parallel file system as well as a new one based on Lustre technology. Wolf operates at 197 teraflops per second and has 9,856 compute cores and 19.7 TB of memory. The machine provides users with 86.3 million central processing unit core hours per year.
Wolf will initially be used for research projects involving climate, material, and astrophysics modeling. "This machine modernizes our mid-tier resources available to laboratory scientists," says Los Alamos High Performance Computing Group's Bob Tomlinson. "Wolf can be used to advance many fields of science."
