Citrix Acquire XenSource to Enter Server and Desktop Virtualization Markets. So whats it has got to do with genetics and bioinformatics , XenSource is the leading provider of enterprise-class virtual infrastructure solutions Originally created by the founders of XenSource at University of Cambridge, the Xen virtualization “engine” is now developed collaboratively by an active open source community.
Scientists were using a 16-node cluster for bioinformatics especially in case of smithman waterman balast, with each node containing a single-core processor. Three years ago, dual-processor nodes became common, so that same scientist needed an 8-node cluster. And then when dual-core became standard, a 4-nodes cluster could take over. With virtualization you can blow it up to many more nodes with no need for any expensive hardware.
