Our main computational resource is a 400 processor research cluster called Anantham. Each node of Anantham has an AMD Opteron 1.4 GHz CPU with 1GB of main memory and a 10GB HDD. The nodes are interconnected over Myrinet interfaces for parallel codes, which use MPI directly over the underlying GM (General Messaging) communication platform. An alternate data path is provided over 100 Mbps switched Ethernet interfaces. The Ethernet interface on each node is used for IP traffic including shared NFS volumes. Ten Ethernet switches interconnected over a two level tree topology provide Ethernet connectivity between the nodes. The Myrinet platform uses one 128 port Myrinet switch and six 16 port Myrinet SAN switches. The Myrinet switches are interconnected over a two level tree topology. The Anantham cluster uses the Linux operating system platform.
The lab in 2000 Torgersen Hall has fourteen workstations based on Apple G5, AMD Opteron and Intel processors configurations running Mac OS X and various distributions of Linux. The workstations are used to support graduate student research.
The lab also has several experimental clusters and shared memory systems for research use. The research clusters are interconnected over Infiniband and Gigabit Ethernet. They include
The lab has a storage server which provides 2TB of RAID storage.
In addition to the experimental clusters, CSRL has access to the 2200 processor System X supercomputer for large-scale systems research.
All of our cluster platforms were built in-house with significant student support. We thank all the students who helped in the initial construction and periodic upgrades of the hardware platforms.
