High Performance Computing Cluster

This HPC cluster is intended for numerical simulation and modeling projects. The cluster consists of 20 Dell PowerEdge 1950 servers with two 2.66GHz quad core Xeon processors, and between 8 and 16GB of RAM each. There are an additional 12 IBM x346 servers with 3.2GHz Pentium4 HT processors, and 4GB of RAM each.

Gas mixing system and sensor test chamber
Gas mixing system and sensor test chamber

We have constructed a gas mixing system and sensor test chamber in-house to support our sensor research program. The system is designed to produce accurate and repeatable concentrations of analytes over a large concentration range (low ppm's to high ppthousand's).
