Areas of Support

Advanced Computing

Science today is more compute intensive than ever before and researchers are realizing that the their computing needs go well beyond the fastest desktops available. At CCR we provide those resources which facilitate science through the use of high end computing. With the cost effectiveness of commodity hardware as well as the software technology in parallel computing, we are able to provide a lower cost and more effective alternative to traditional "main frame" systems.

Our Advanced Systems administration staff has the expertise apply the latest techniques in high performance computing to design, configure, install and maintain these resources.
