Computing Resources at SDSC: Quick Comparison
It is important to choose the SDSC resource that best suits your computing requirements. The information below describes each resource's intended purpose and system configuration.
WARNING: It is your reponsibility to back up critical data! Please maintain your own copy of important data stored on SDSC file systems.
Recommended Use
- TeraGrid IA-64 Linux Cluster: For computations requiring smaller processors counts (<512).
- BlueGene/L: For code that scales very well, only fine-grained parallelism with strict restriction on memory per node.
