Nearly every supercomputer runs Linux

Just as with the previous list of the Top500 Supercomputers, the Oak Ridge National Laboratory's Cray XT5 'Jaguar' leads the pack with a sustained performance of 1.76 PFlop/s. However, a new Chinese entrant called Nebulae has achieved a higher peak performance of 2.98 PFlop/s (compared to Jaguar's peak of 2.33 PFlop/s) and is placed second overall.

Of the 187 new entrants, all but one are running some variant of Linux and in fact 470 of the Top 500 run Linux, 25 some other Unix (mostly AIX) and the remaining 5 run Windows HPC 2008.

The Chinese systems Nebulae and 7th placed Tianhe-1 are both based on a hybrid design with each node comprising a pair of Intel Xeon processors attached to a pair of GPUs (NVidia for Nebulae and AMD for Tianhe-1) as accelerators. These two systems helped China to take second place for total PFlop/s (9.2%), still trailing USA with 55.4%.

Australia has just one entry in the list

7 killer open source monitoring tools

Network and system monitoring is a broad category. There are solutions that monitor for the proper operation of servers, network gear, and applications, and there are solutions that track the performance of those systems and devices, providing trending and analysis. Some tools will sound alarms and notifications when problems are detected, while others will even trigger actions to run when alarms sound. Here is a collection of open source solutions that aim to provide some or all of these capabilities. Read more

Reader Forum: Accelerating ‘IoT’ with an open-source, embedded platform for connected applications

Providing an end-to-end solution for building and deploying new connected applications extremely quickly, at scale, and at a fraction of the cost compared to conventional processes is key to streamlining M2M development. And, using an open-source, Linux-based platform, companies can run applications on any vendor’s hardware and use any cloud management platform. Read more

REPRISE OF AKADEMY 2014: ARTIKULATE

Even when it sounds like KDE Akademy is a just big party, we have been very productive as well. During the birds-of-a-feather (BoF) session on user experience, we discussed usability and visual design for some projects. Here we want to report about the first one: Artikulate. Read more

Technology on a Diet: 5 Reasons to Embrace Open Source

Sharing information in the name of innovation isn’t anything new. Collaborative intelligence helped publish the Oxford English Dictionary, spur advances in 19th century science and powered the world’s first automobile. Even Ben Franklin insisted on donating his bifocals and lightning rod to the public domain, likely dubbing him America’s first open-source advocate. The notion of “open source” predates software and the Internet by centuries, yet many of today’s largest government IT shops are still reluctant to turn to open alternatives from proprietary software, even in the face of shrinking budgets, overworked staff and heightened citizen expectations.
