This week AMD announced the shipment of the first processors based on its new x86 “Bulldozer” architecture to CSCS and other supercomputer centers. The processors will be used to upgrade the Monte Rosa supercomputer from a Cray XT5 to a Cray XE6 in October. AMD announced on his web pages that “The first parts off the [...]
Earlier this year, CSCS hosted a tutorial called “Molecular Dynamics Codes on GPGPUs” — it provided an overview of classical molecular dynamics software, showed some benchmarking results, and gave a hands-on walkthrough using GPU-accelerated MD codes. CSCS published a brief summary of the benchmarking results that were featured in the tutorial. CSCS looked at two [...]
CSCS is happy to announce that the next-generation Cray XMT has been delivered and assembled. During the acceptance tests CSCS were able to reproduce the numbers submitted to the Graph500 last month. The Cray XMT supercomputer is named “Matterhorn” after the very famous Swiss mountain and it is now ready to be used. For detailed [...]
CSCS evaluated two different PCIe attached SSD devices with various methods for analyzing bandwidth and IOPs. The performance over SATA drives is huge as expected, by a factor of 20 in bandwidth and a factor of 1500 for IOPs. The results indicate, that SSDs are a valid alternative for SATA or SAS drives in terms [...]
Since October 2009 CSCS uses xCAT in some production environments. xCAT is an open source HPC cluster management. It is agile, extendable, and based on years of system administration best practices and experience. Carmelo Ponti of CSCS contributed to the project with a “Getting Started” document » Please contact Carmelo (cponti at cscs.ch) for additional [...]
