Windows HPC: Who is it for?

• Research groups who work on Windows workstations and need a local computing capability for their day-to-day calculation, often as a complement to the large shared cluster in their institution that requires reservation. Their requirements:– Use of the cluster must be as easily as possible for a non-IT skilled scientist– Cluster must be managed by their standard local IT

• Scientists and engineers that develop code on their Windows workstations and want to expand them onto a cluster with as little effort as possible

• Academic institutions that want to open their grid infrastructure to new types of users, optimize their investment in hardware and foster new research initiatives

• Academic institutions that want to prepare their students to all the computing environment alternatives they will encounter in their careers

Expanded its cluster to include Windows HPC to support a growingnumber of Windows-based parallel applications

“A lot of Windows-based development is going on with the Microsoft® Visual Studio® development system, and most researchers

have a Windows PC on their desk,” says Christian Terboven, Project Lead for HPC on Windows at the CCC.

“In the past, if they needed more compute power, these researchers were forced to port their code to UNIX because we offered

HPC services primarily on UNIX.”

“Windows HPC Server 2008 will help us extend our user base by taking high-performance computing to new user communities in a way we were unable to do before”

“Porting codes from Linux to Windows HPC Server 2008 was very easy and painless. I was running the ported code within a day”

Leading Supercomputing Center in Italy improves access to supercomputing resources for more researchers from private industry sectors, many of whom were unfamiliar with its Linux-based tools and interfaces

“Most researchers do not have time to acquire specialized IT skills. Now they can work with an HPC cluster that has an interfacesimilar to the ones they use in their office environments. The interface is a familiar Windows feature, and it’s very easy tounderstand from the beginning”
