Over at HPC for Energy, Carl Bauer writes that High Performance Computing is the key to meeting the daunting energy challenges that face the nation. U.S. high-performance computing capabilities resident at our national laboratories can turn these challenges into an opportunity for competitive advantage. What was once only available for unique, extremely important and expensive government research projects or the largest corporations is now available...

A low level counterpart language to Lua offers a new way of generating high performance code and compiling domain specific languages for HPC applications...

ScaleMP uses its vSMP aggregation hypervisor and cheap skinny nodes to boost main memory Over at The Register, Timothy Prickett-Morgan writes that ScaleMP has cooked up some new ways to build big memory machines for less money. In the example above, the workload in question only needs a four-socket Xeon E5-4600 or Xeon E7-4800 in terms of the processing capacity, but the 48 to 64 memory sticks in this box do not offer enough main memory capacity, and moreover, the fat memory needed to build up terabytes of memory space are very expensive. So instead of buying an eight-socket box to get...

Over at the Intel Datastack Blog, Winston Saunders writes considering the rapidly expanding efficiency and performance capability of supercomputing systems, it may be time to upgrade just for the electricity savings alone. You can see system-level annualized energy costs in the Figure. From this point it is pretty straight forward to...
