HP Opteron
QSR (qsr.cnsi.ucsb.edu)
This system is best suited for serial or small parallel jobs. Each node has four cores (think processors) Opterons, so either 4 serial or a single 4-way parallel job can be run on each node.
QSR is named for the Quantum Science Research Lab at HP, one of the groups that CNSI works with.
Technical Details
QSR is configuration is be based on dual-core, dual processor HP DL145 computers. The head node has 4GB RAM, and 4TB of disk storage, while the 32 compute nodes have 8GB RAM and 80GB of local disk storage. There are two parallel Gigabit Ethernet networks, one for general MPI, NFS, etc. traffic, and one for administration.
