Linux Parallel Computing Clusters

A computational cluster is collection of computers networked together to form a single high-performance computing (HPC) system. There are a number of HPC resources available to PSU faculty, staff, students, and their collaborators who are interested in running existing applications, or developing new parallel code. Research Computing (RC) is working with PSU research faculty to increase the number of nodes available for tackling large problems and maximizing our parallel computing capability. 

RC has a computational cluster for research computing projects which require parallel processing with Message Passing Interface (MPI). Parallel computing clusters can result in a massive performance increase with a much lower hardware cost than a traditional symmetric multiprocessing system. Parallel computing is already used for purposes such as weather forecasting, phylogenetic tree building, fluid systems modelling, and molecular interaction modelling.

These systems can also be used for non-parallelized applications. Clusters can be used to run single isolated processes on a compute node, or many copies of the same process (for instance, for the purpose of statistical validation).

OIT Systems

Coeus HPC Cluster

The Coeus HPC cluster is the cornerstone of a new computational infrastructure to support the Portland Institute for Computational Science, and Research Computing at Portland State University. As the Titan god of knowledge and intellect in Greek mythology, Coeus represents the inquisitive mind and the personification of our research and educational goals.

This computational cluster is designed to address a broad range of computational requirements. Coeus is adept at handling parallel high-performance computing (HPC) workloads. It also supports “traditional” single-threaded and multithreaded processes like Matlab, R, and other standard scientific applications. Provided and built by Advanced Cluster Technologies, this cluster has an estimated peak performance of over 100 TFLOPs, Intel Omni-Path high performance networking (100 Gbps), and approximately 190 TB scratch storage.
