The University of Pittsburgh established the Center for Molecular and Materials Simulations (CMMS) in 2000, providing computational resources to researchers in the Sciences and Engineering. The effort to establish CMMS was spearheaded by researchers in the Departments of Chemistry and Chemical Engineering with support being provided by the College of Engineering and the School of Arts and Sciences.
When originally established in 2000, the resources in CMMS included a 50-CPU IBM RS6000 POWER3 workstation cluster and a 9-processor Pentiumiii cluster. Sixteen of the RS6000 computers were connected optically via switched Gigabit Ethernet to provide parallel processing applications using up to 32 CPUs. Funding for this hardware was provided by the Major Research Instrumentation (MRI) program of the National Science Foundation and the SUR program of IBM.
