A Star for Cyberinfrastructure
SDSC operates powerful high-end computing resources including DataStar, a 15.6 teraflop IBM Power4+ supercomputer with total aggregate memory of 7.3 terabytes. DataStar is ranked among the top supercomputers in the world and is used for large-scale, data-intensive scientific research applications.

The use of 8-way nodes is exclusive: only one user is allowed at a node at any time, regardless of the number of CPUs one needs on that node. The use of 32-way nodes is shared among users. CPU and memory usage on these nodes is subject to limits specified by users in their batch scripts.
Recommended Use Guidelines
SDSC's DataStar p690 partition (with six 32-processor nodes) is primarily intended to run applications that require large amounts of shared memory such as pre- or post-processing data for large-scale calculations or repeated database operations. Four nodes have 128 GB of shared memory, and two of the 32-processor nodes have 256 GB of memory.
