Wim Slagter's personal impressions of ISC 2015 at the ANSYS blog: "Regarding HPC systems, I can mention that there is a major change in vendor market share leadership. In the past, HP and IBM were the leaders. After Lenovo’s acquisition of the x86-server business from IBM in 2014, HP is the clear market leader and Lenovo is now a major player, almost tied with Dell." notes Slagter. He also notes that HPDA (high performance data analytics), where HPC and Big Data come together, creating new opportunities (also in CAE), new use cases, and more demand on IT infrastructure.

Supercomputers deliver only a few percent of their theoretical peak performance so people should reset their expectations of Exascale, writed Tom Wilkie in Scientific Computing World/ he heard at ISC High Performance earlier this month. Wilki talked to HLRS director Michal Resch: "According to Resch, simple arithmetic meant that if an exascale machine achieved a sustained performance of only 1 to 3 percent, then this would deliver 10 to 30 Petaflops. So buying a 100 Petaflop machine that was 30 per cent efficient – which should be achievable, he claimed – would deliver the same compute power, for a much lower capital cost and about one tenth the energy cost of an exascale machine."

Applications

Chipster is a user-friendly analysis software for high-throughput data integrated in the EGI Federated Cloud and developed by CSC, the Finnish IT Center for Science and ELIXIR node. A comprehensive set of video tutorials is now available on YouTube. Chipster contains over 340 analysis tools for next generation sequencing (NGS), microarray, proteomics and sequence data and allows users to save and share automatic analysis workflows or to visualize data interactively using a built-in genome browser. The video tutorials released this week on a dedicated YouTube channel aim to stimulate adoption. The tool is fully integrated in the EGI Federated Cloud, using cloud resources provided by INFN-Bari (part of the Italian NGI). Read further...
