iSCAN Cluster

Introduction

The iSCAN cluster is a part time cluster made up of lab machines.  It is available only in the evenings when the labs are closed.  The hardware and software specifactions can be found below.  The current benchmarks of the current system and a list of projects using the cluster are also available below.
