In this slidecast, Einar Rustad from Numascale describes how the company achieved a world-record on the McCalpin STREAM benchmark using their innovative scale-out to scale-up architecture. The benchmark measures sustainable memory bandwidth and the corresponding computation rate for simple vector kernels.
Today JISC in the U.K. announced that Rolls-Royce is the first company to join its industrial supercomputing initiative. Designed to break down barriers between industry and academia, JISC will provide Rolls-Royce with easy access to supercomputing equipment at the Engineering and Physical Sciences Research Council (EPSRC) HPC Midlands.
Over at Scientific Advances, a newly published paper describes a new high-efficiency computing paradigm called memcomputing. Modeled after the human brain, a memprocessor processes and stores information within the same units by means of their mutual interactions. Now, researchers have built a working prototype.
Bill Gropp from the University of Illinois at Urbana-Champaign presented this talk at the Blue Waters Symposium. “The large number of nodes and cores in extreme scale systems requires rethinking all aspects of algorithms, especially for load balancing and for latency hiding. In this project, I am looking at the use of nonblocking collective routines in Krylov methods, the use of speculation and large memory in graph algorithms, the use of locality-sensitive thread scheduling for better load balancing, and model-guided communication aggregation to reduce overall communication costs. This talk will discuss some current results and future plans, and possibilities for collaboration in evaluating some of these approaches.”
