One of the most complicated aspects of using supercomputers revolves around sending data to the various supercomputing resources of the Oak Ridge Leadership Computing Facility (OLCF), a DOE Office of Science User Facility located at ORNL. The OLCF’s flagship supercomputer, a Cray XK7 called Titan, sends data between storage systems, analysis clusters, and transfer nodes using the Atlas file system. Atlas contains roughly 20,000 disk drives housed within 72 controllers to handle supercomputer-sized data sets, making the task of monitoring Titan’s system far more involved than monitoring a laptop’s system. For years, DataDirect Networks (DDN) has partnered with the OLCF to help build these disk drives. However, because of the vast number of disk drives, the OLCF needed to develop a more efficient performance monitoring tool. The new DDNTool software is designed to gather data from all 72 controllers and aggregate it.id OLCF staffer Ross Miller. Read further...

Jülich Supercomputing Centre (JSC) organises a workshop "Supercomputing for Neuroscientists - How High-Performance Computing (HPC) can help your neuroscience projects" on 3 November 2015. This workshop aims at bringing neuroscientists interested in using HPC technology for their projects together with experts from the Jülich Supercomputing Centre’s Simulation Laboratory Neuroscience whose main goal is to bridge the gap between Computational Neuroscience and HPC.

According to Quentin Hardy on the New York Times site, Google follows Amazon Web Services into on-demand supercomputing. On Wednesday, Google announced the general availability of something called pre-emptible virtual machines, which amount to computing resources you can rent for very little, Hardy says. The addition of Google as a competitor to Amazon Web Services is likely to increase the number of ways these resources are used while lowering prices. Google also appears to be stressing its skills in machine learning, a powerful tool for finding new patterns in large data sets. Read further...
