Here is an old saw that we bring out of the toolbox every now and then, and we use it just enough so it has never really gotten rusty and it can cut through a lot of crap to make a point: The datacenter, and perhaps all clients, would have been better off if InfiniBand had just become the ubiquitous I/O switched fabric standard it was designed to be back in the late 1990s. …
Frustrated by the limitations of Ethernet, Google has taken the best ideas from InfiniBand and Cray’s “Aries” interconnect and created a new distributed switching architecture called Aquila and a new GNet protocol stack that delivers the kind of consistent and low latency that the search engine giant has been seeking for decades. …
Whenever one company buys another, every product line, every research project, and every employee is ultimately in play. …
Hewlett Packard Enterprise has been building a mainstream and grassroots server business aimed at large enterprises, HPC centers, and academic and government institutions for two decades. …
It happens all the time. There is a performance problem, and everyone blames the network. …
System architects that live in the Seattle area who don’t want to uproot their lives and move to California or Texas or New York or maybe possibly Illinois or Oregon or even overseas to Japan or China have a fairly small number of job opportunities. …
The first exaflops-capable supercomputers are just around the corner and to celebrate this milestone-to-be and talk about its ramifications, the US Department of Energy hosted a national “Exascale Day” discussion. …
Last fall, supercomputer maker Cray announced that it was getting back to making high performance cluster interconnects after a six year hiatus, but the company had already been working on its “Rosetta” switch ASIC for the Slingshot interconnect for quite a while before it started talking publicly about it. …
After a long wait, now we know. All three of the initial exascale-class supercomputer systems being funded by the US Department of Energy through its CORAL-2 procurement are going to be built by Cray, with that venerable maker of supercomputers being the prime contractor on two of them. …
When Oak Ridge National Laboratory installs its 1.5 exaflops Frontier supercomputer in a couple of years, it’s likely to be the most powerful system in the US, if not the world. …
