Amazon’s cloud is the world’s 42nd fastest supercomputer

The list of the world’s 500 fastest supercomputers came out yesterday with a top 10 that was unchanged from the previous ranking issued in June. But further down the list, a familiar name is making a charge: Amazon, with its Elastic Compute Cloud service, built a 17,024-core, 240-teraflop cluster that now ranks as the 42nd fastest supercomputer in the world.

Amazon previously built a 7,040-core, 41.8-teraflop cloud cluster that hit number 233 on the list, then fell to 451st. But Amazon submitted an updated Linpack benchmark test with the addition of a new type of high-performance computing instance known as "Cluster Compute Eight Extra Large," which each have two Intel Xeon processors, 16 cores, 60GB of RAM and 3.37TB of storage. The full cluster on the Top 500 list is Linux-based, with 17,024 cores, 66,000GB of memory, and a 10 Gigabit Ethernet interconnect.

via Amazon’s cloud is the world’s 42nd fastest supercomputer. I posted about this on Twitter, but it’s still a little astonding. Amazon built EC2 primarly to serve as their internal infrastructure, today a piece of it made it on the list of the fastest supercomputers in the world.
