Virtualization Meets HPC at Oak Ridge

As reported at InsideHPC, Sun’s Josh Simons has posted an interesting report on the state of Virtualization for HPC:
“Resiliency isn’t something the HPC community has traditionally cared much about. Nodes were thin and cheap. If a node crashed, restart the job, replace the node, use checkpoint-restart if you can. Move on; life on the edge is hard. But the world is changing. Nodes are getting fatter again–more cores, more memory, more IO. Big SMPs in tiny packages with totally different economics from traditional large SMPs. Suddenly there is enough persistent state on a node that people start to care how long their nodes stay up. Capabilities like Fault Management start to look really interesting, especially if you are a commercial HPC customer using HPC in production.” Full Story

About Rich
FlexRex began his life as a cartoon character I created a Sun Microsystems. As the world's first "fictional blogger," he appeared in numerous parody films that made fun of the whole work-from-home thing. Somewhere along the line, the Sun IT department adopted FlexRex as their spokesman in a half-dozen security awareness films for employees. So when I left Sun recently, I started FlexRex Communications, a Marketing company in Portland, Oregon.
