Rosa Introduction Course Summer 2010


The Swiss National Supercomputing Centre (CSCS) will host an introduction course on its production computing platform, Rosa, between the 14th and 15th of June 2010, Manno. Rosa is the main production facility at CSCS. It is a 20 cabinet liquid cooled Cray XT5 system with a theoretical peak performance of 212TFlop/s and 29 Terabytes of main memory. 

The introduction course will provide both existing and new users an introduction to the Rosa system including detailed information regarding the Cray XT5 hardware, software architectures and programming environments.

Furthermore, users will be gain practical experience with high-level profiling and optimization techniques on the new system, through a series of hands-on exercises.

Registration fee

This event is free of charge.
