Phoenix PhaseC Upgrade Passed Acceptance Test

Wednesday, March 31st, 2010

CSCS is happy to announce that  Phoenix PhaseC Upgrade passed today the acceptance test. Phoenix is a HPC system run by CSCS used by the researchers of the Swiss Institute of Particle Physics CHIPP to analyze the data from the LHC experiment at CERN.

The upgrade has been delivered and installed by Sun and will double the computing and storage capacity provided by the previous system (also from Sun). The main characteristics of the new cluster are:

  • 96 Sun X6275 compute nodes with in total 768 cores running at 2.56 GHz (Intel E5540)
  • 7.6 TFlops peak performance
  • Lustre 115 TB usable space with a 7.6 GB/s write speed used as scratch
  • 10 Thors X4540 with480 TB total space (plus 672 TB Thumper recycled from PhaseB) used to store experiment data
  • Infiniband QDR used as interconnect

In the next days the system administrators at CSCS will migrate the middleware from phase B to C. PhaseC should be fully operational on Montay, April 19th. You can follow the next steps of the upgrade on twitter: http://www.twitter.com/phoenix_cscs

Today we also had the handover of the system responsibility from Fotis (right on the next picture) to Pablo. We thank Fotis for all the excellent job made so far. He has helped make Phoenix into a great cluster during these last 18 months, together with Jason and Riccardo, making it challenging for others to achieve the same quality. Pablo has an extensive GRID background and has been working with us for two months, during which time he has learned the daily procedures at CSCS-LCG2 grid site and is ready to succeed Fotis as system lead.

Case Study of University of Zurich and Intel on High-Performance Computing

Monday, January 25th, 2010

University of Zurich and Intel commonly announced a case study for the use of Intel® Xeon® processor 5500 and 5400 series for Schrödiger, the new Sun HPC system of the university.

The University has been at the forefront of scientific research for many years and relies heavily on its HPC cluster to underpin complex calculations and simulations. Its environment was beginning to age, resulting in slow response times and even the inability to carry out certain simulations.

Dr. Alexander Godknecht, head of IT-infrastructure, bioinformatics and HPCN, IT Services at the University of Zürich, explains: “Many of our compute-heavy departments were having trouble getting what they needed out of the old platform. The astrophysics team, for example, needs large amounts of memory to carry out its calculations while the physical chemists require fast networks with low latency and multiple cores in order to get the compute performance to support their computations. Meanwhile, the biochemistry researchers were hardly able to compute their thousands of simulations as the time taken to do them was just too long.”

University of Zurich selected for the new HPC system called Schrödinger a solution provided by Sun and Intel. The environment deployed is underpinned by six 48-blade racks of Sun Blade X6275 server modules, powered by a total of 4,608 Intel Xeon processor 5500 series cores. Running a SUSE Linux Enterprise* operating system, it supports all the applications used by the various departments to ensure the cluster is kept free to run the parallel applications for which the Intel Xeon processor 5500 series is optimised.

“We´re confident that the new cluster provided by Sun and Intel will last us for a good few years and enable us to push ahead with new scientific breakthroughs that Schrödinger himself would be proud of,” concludes Dr. Godknecht. The industry has already recognised the University´s new cluster by ranking it 96th in the Top 500 Supercomputers worldwide.

While the cluster is currently used exclusively by scientists based at the University of Zürich, it forms a part of the general HPC strategy in Switzerland led by the Swiss National Supercomputing Centre (CSCS). Like other countries, Switzerland has a strategy for a national HPC infrastructure. A grid or a series of smaller clusters form the base of the pyramid, followed by big clusters like Schrödinger and at the top of the national pyramid will be the planned Petabytelevel Supercomputer at CSCS. By providing a platform where scientists can write and test codes for thousands of processing cores, the University of Zürich will be part of the Swiss national plan for High Performance Computing and Networking.
