After already shipping more than half a million of its next-generation Xeon products to customers, Intel officially launched its new Xeon scalable processor product line. The chipmaker is calling it the “biggest data center advancement in a decade.”
Japanese computer-maker Fujitsu is developing an AI-specific microprocessor called the Deep Learning Unit (DLU). The company’s goal is to produce a chip that delivers 10 times better performance per watt than the competition.
For all the supercomputing trends revealed on recent TOP500 lists, the most worrisome is the decline in performance growth that has taken place over the over the last several years – worrisome not only because performance is the lifeblood of the HPC industry, but also because there is no definitive cause of the slowdown.
In March, ministers from seven of the largest European countries signed a declaration that established a timeline for fielding two exascale supercomputers in 2022. The agreement also specified that at least one of these systems will be based on European technology, although, as it turns out, not everyone seems to think this is the best way forward.
Even though there wasn’t much turnover in the latest TOP500 list, a number of new petascale supercomputers appeared that reflect a number of interesting trends in the way HPC architectures are evolving. For the purposes of this discussion, we’ll focus on three of these new systems: Stampede2, TSUBAME 3.0, and MareNostrum 4.
For the first time in several years, AMD has brought a server chip to market that provides some real competition to Intel and its near total domination of the datacenter market. The new AMD silicon, known as the EPYC 7000 series processors, come with up to 32 cores, along with a number of features that offer some useful differentiation against its Xeon competition.
The fourth-generation MareNostrum supercomputer is up and running at the Barcelona Supercomputer Centre (BSC), or at last the first phase of it is. When completed, it will contain the most interesting medley of processors of any supercomputer in existence. We asked Sergi Girona, Director of Operations at BSC, to describe the makeup of the new system and explain the rationale for building such a diverse machine.
The recent upgrade to the Piz Daint supercomputer at the Swiss National Supercomputing Centre (CSCS), has thrust the machine into limelight here at the ISC High Performance conference on opening day. The Cray XC50 system turned in a Linpack result of 19.6 petaflops, which was good enough to capture the number three spot on the latest TOP500 list, and displace Titan, the former GPU supercomputing champ, running at Oak Ridge National Laboratory.
In 1999, Peter Braam introduced Lustre, an open-source parallel file system which went on to become one the most popular software packages for supercomputing. Braam’s success with Lustre was just the start of a career in which he founded five companies and guided technology development in numerous others -- Sun Microsystem, Red Hat, and Xyratex, among them. He’s currently working with Cambridge University on the Square Kilometer Array project and its Science Data Processor effort.
When assessing the fastest supercomputers in the world, system performance is king, while the I/O componentry that feeds these computational beasts often escapes notice. But a small group of storage devotees working on a project at the Virtual Institute for I/O (VI4IO) want to change that.
