The USA has gained ground in the world supercomputer rankings, with
116 supercomputers listed among the top 500 most powerful in the world.
This is up from 109 in November 2018. China continues to dominate the list in terms of the number … Continue reading USA gains ground in supercomputer world rankings
HPE announced it was buying Cray for $1.3 billion, giving it access to the company’s high performance computing portfolio, and perhaps a foothold into quantum computing in the future. The purchase price was $35 a share, a $5.19 premium over yesterday’s close of $29.81 a share. Cray was founded in the 1970s and for a […] Continue reading HPE is buying Cray for $1.3 billion
Somewhere in the recesses of my memory there lives a small photograph, from one of the many magazines that fed my young interests in science and electronics – it was probably Popular Science. In my mind I see a man standing before a large machine. The man looks awkward; he clearly didn’t want to pose for the magazine photographer. The machine behind him was an amazing computer, its insides a riot of wires all of the same color; the accompanying text told me each piece was cut to a precise length so that signals could be synchronized to arrive at …read more
Sometimes it is hard to remember just how far computers have come in the last three or four decades. An old NASA video (see below) has been restored with better sound and video recently that shows what passed for a giant computer in 1986. The Cray 2 runs at 250 MHz and had two gigabytes of memory (256 megabytes of 64-bit words).
Despite the breathless praise, history hasn’t been kind to the Cray 2. Based on ECL, it had 4 processors and –in theory — could reach 1,900 megaFLOPs/second (a FLOP is a floating point operation). However, practical problems made …read more
The name Cray, as in [Seymour Cray] is synonymous with supercomputing. If you hurry, you can bid on a Cray J90/J916 on eBay. You might want to think about where to put it though. It is mounted on a trailer, requires 480V, and the shipping is $3,000!
First introduced in 1994, the J90 was an “entry level” machine. This particular machine supported up to 16 CPUs (each CPU was actually two chips) running at a blazing 100 MHz. The memory system was more impressive, achieving 48 GB/s.
The Cray T90 computer was much faster (and more expensive) but none of …read more

Microsoft and Cray have announced a partnership that will bring physical Cray supercomputers to the Azure cloud.
The post Cray Supercomputers in Microsoft Azure appeared first on Petri.
Cray has always been associated with speed and power and its latest computing beast called the Cray Urika-GX system has been designed specifically for big data workloads. What’s more, it runs on OpenStack, the open source cloud platform and supports open source big data processing tools like Hadoop and Spark. Cray recognizes that the computing world had evolved since Seymour Cray… Read More Continue reading Cray’s latest supercomputer runs OpenStack and open source big data tools
