Description

Quasar is a research system which ARSC is using to investigate Cell Broadband Engine processor technologies. The Cell Broadband Processor was first introduced in the Sony Playstation 3 but has also proved useful for some scientific applications. Quasar has 4 GB of memory per PowerXCell 8i processor as well as a fast Infiniband network which should make the system suitable for a wide range of high performance computing applications.

As a research system, technical support for quasar is provided on a "best effort" basis.
