Computational Resources at the Lab

The High Performance Computing Lab has access to SERC's excellent computational facilities, and also possesses its own high performance hardware.

GPU Systems

These are dedicated GPGPU systems. Also see the CC cluster down for more GPGPU support.

Lab Cluster

The in-lab cluster is a 16-core cluster (20, if you count SMT/HT as two) that is heavily used for architectural simulations. It also helps keep the lab warm in the cold Bangalore winters. More than one machine in this cluster has cracked under the stress!


Mrugesh and the Lab cluster.

All machines in the cluster are equipped with Gigabit Ethernet connectivity for fast transfers of gigabytes of simulation data.

jal, zulu, quark, trinity

The newest additions to the cluster, these are Intel Core 2 Duo E4400 @ 2GHz, with 2GB RAM and 250GB HDD each. Cool and quiet, they outperform the older cluster machines despite having a lower clock rate!

Configuration
ProcessorIntel Core 2 Duo E4400 2GHz
Memory2GB
Storage250GB
InterconnectGigabit Ethernet
Operating SystemDebian Etch 4.0

These 64-bit machines run Debian Etch 4.0, but in different flavours:

neo, budha, shrek, raman, viveka, ashoka, panini, maggie

Old workhorses of the cluster, Intel Pentium 4-based 3.4GHz with Hyperthreading, 1GB RAM, and 80GB HDD each. Temperamental, hot (as in temperature) machines.

Run Debian Etch 4.0, Ubuntu, Kubuntu and Fedora Core 3, with some running Windows XP as well.
