High-end storage tanked, but 'HDPA' storage about to soar says IDC

Box-counter IDC recently decreed that 2014's first quarter was a shocker for high-end storage sales, but also predicts things are looking up in storage used for what it now calls “high performance data analysis” (HPDA). IDC's veep for HPC and data analysis Steve Conway puts HDPA in a little perspective with a canned quote …

Sod Bitcoin - solving graph problems is the new GPU-flogger

HPC blog These GTC conferences, the annual GPU-fest sponsored by NVIDIA, are my favorite events of the year. Why? It’s how the event is organized. At GTC, real-world researchers, analysts, and other customers present the vast majority of sessions, not corporate mouthpieces. They talk about their projects, the challenges they’ve dealt …

Petascale powerhouse cracks important HIV code

The Blue Waters petascale computer at the University of Illinois' National Centre for Supercomputing Applications is being credited with cracking part of the code of HIV – and possibly helping point the way to new treatments. Simulations carried out on Blue Waters allowed researchers to determine the precise structure of the …

IBM considers System X surgery: Will it ruin its sexy HPC figure?

HPC blog The increasing amount of speculation over IBM's potential unloading of all or part of its System x (x86-based servers) business onto Lenovo has high performance computing (HPC) players wondering about the implications for the sector. What would be the eventual impact on IBM, and the HPC market in general, if Big Blue were to …

HPC cluster cowboys bag overall award, haul it home to Texas

SC12 Video I caught up with Team Longhorn just before they turned in their final results for the SC12 Student Cluster Competition (SCC). As you can see in the short video, they’re pretty cool and composed, but I thought I sensed a little bit of anxiety under the surface. As it turns out, they should have been more relaxed – they were …

FINAL NIGHT: Boston kids power down cluster compo systems

SC12 Early on the last day of the SC12 Student Cluster Competition, I hit a couple of morning meetings and then went wandering around the competition area. Most of the teams had at least two or three reps in the booths monitoring the systems and just sort of hanging around. They had turned in their final scientific results the night …

Team Utah grabs Mini Iron crown at little cluster compo

SC12 Until this year, the annual SC Student Cluster Competition focused entirely on seeing how much work teams of university students could wring out of 26 amps of juice. They can use any hardware/software combination that will run the required apps; the only limitation is that their configuration has to be shipping by the time of …

Team Boilermaker: We hammer the code... not the booze

SC12 Video We had a chat with Team Boilermaker on the last day of the SC12 Student Cluster Competition. While the team did visit several of the vendor parties the night before, they assert that they didn’t overindulge, and claim that the absence of some team members is due to meetings, not hangovers. I think I buy that explanation; …
