Today many different interconnection topologies are used for multicore chips. For as few as eight cores direct bus connections can be made — cores taking turns using the same bus. MIT’s 36-core processors, on the other hand, are connected by an on-chip mesh network reminiscent of Intel’s 2007 Teraflop Research Chip — code-named Polaris —… Continue reading MIT Puts 36-Core Internet on a Chip | EE Times
“Were here today shipping a 64-bit processor core and we are what looks like two years ahead of ARM,” says Bishara. “The architecture of the Tile-Gx is aligned to the workload and gives one server node per chip rather than a sea of wimpy nodes not acting in a cache coherent manner. We have been… Continue reading Tilera preps many-cored Gx chips for March launch • The Register
Tilera’s roadmap calls for its next generation of processors, code-named Stratton, to be released in 2013. The product line will expand the number of processors in both directions, down to as few as four and up to as many as 200 cores. The company is going from a 40-nm to a 28-nm process, meaning they’re… Continue reading Tilera | Wired Enterprise | Wired.com
Wired.com isn’t the best at following the Cloud Data Industry. In fact at least they partially want to keep their advertisers happy so they will publish a Fear, Uncertainty and Doubt raising response direct from an Intel PR Engineer. Happily the Intel folks aren’t even fully aware of what people are doing with their SeaMicro and Quanta SQ-2 boxes and continue to beat the drum on Virtualized Servers on Multi-core, high-clocked chips. That’s the old school thinking on what a Compute Cloud can be. The New School says put the cloud in a single box, let the clock run slower and use less power and everybody wins. Read On:
It seems like massive scale multi-core cpus are increasing in popularity. A third party competitor is entering the market with a mobile cpu co-processor. Adapteva is announcing the Epiphany co-processor, but the question is really what’s it good at, and who is going to integrate it into a new phone design. Read On:
One of the more radical departures from of the off the shelf commodity data centers built on Intel is the Quanta SQ-2. Based on the Tilera chip, it has multiple cores (many more than an equivalent Intel Architecture) and uses a mesh network on chip to speed communications between the cores. It’s been a long, low, slow slog to get Tilera to market in any product other than a network switch or comm switch of any sort. But according to Facebook, Tilera shows promise in the clock cycles/versus energy consumption category. Read On:
Seamicro just keeps cranking out new product. They are like the Apple of the massively parallel cloud computer in a box segment of the industry. They just recently moved from old style x86 32bit Intel Atom CPUs to fully x64 capable cpus. And now the increased the density of the cpus on each compute node within their 10U server box, bringing the grand total of cores up to a staggering 768!
I still have great hopes for Tilera in the data center cloud market place. But the only real competition out there now is Seamicro’s own SM-10000×64 which is tearing up the charts with Intel’s Atom N570. Once Tilera is able to ship its chips in volume and get manufacturers to start building servers with Tilera CPUs inside, it will be a true horse race.
What darkness lurks in the hearts of men? Only the shadow knows right? Or possibly a Tilera Chip sitting in an NSA data skimming operation located at your local Internet GigaPOP.
After Facebook’s presentation at the Open Compute Day, I got to thinking more about other competitors in the market for the low energy consumption data center. And while everyone including Google remain loyal to Intel, the smaller upstarts have an opportunity to raise their marginal return if they choose wisely. I say this in part due to the folks like Seamicro and Tilera and ARM who are attempting to provide equal compute cycles per core, while running back the voltage and amperage required for each tick-tock of the CPU clock. Experts in the field of Electronics Engineering claim serial processors will always carry the day, but what price progress if we hold onto Amdahl’s Law for too long?
