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 [...]
CSCS will install by the end of June, 2011 a new Cray XMT. James Maltby of Cray presents the new supercomputer and its new possible applications for science and industry. James explains how easy it is program this supercomputer supporting massive hyperthreading. Have a look!
Whether data is processed or deleted in computers, both consume energy. The energy is released as heat. A study has now shown that the heat forming can be avoided, and, in an extreme case, cold can be created – a glimmer of hope for supercomputer centres. The deletion of data, under certain conditions, can create [...]
