About Scicluster¶
A Linux Cluster - one machine, consisting of many machines¶
On one hand you can look at large Linux Clusters as rather large and powerful supercomputers, but on the other hand you can look at them as just a large bunch of servers and some storage system(s) connected with each other through a (high speed) network. Both of these views are fully correct, and it’s therefore important to be aware of the strengths and the limitations of such a system.
Rocks Gnu/Linux operating system¶
Scicluster is build upon Rocks cluster distrobution. Rocks is an open-source Linux cluster distribution that enables end users to easily build computational clusters, grid endpoints and visualization tiled-display walls. Hundreds of researchers from around the world have used Rocks to deploy their own cluster

Currently all nodes in the cluster are connected with a 1 Gb ethernet network as well as a 10 Gb low latency one for message passing.
