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 — […]
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 […]
By itself Calxeda has made some big plans attempting to create computers like the SeaMicro SM10000. But the ability to manufacture on any scale and then sell that product is a bit limited. But as of today HP has partnered with Calxeda to sell product and help design a server using the reference design for a compute node. So the ball is rolling, and now there’s a third leg in this race between the Compute Cloud in a Box manufacturers (Calxeda, SeaMicro and Tilera). Read On:
In past readings of announcements and analysis of announcements from ARM and Calxeda, I got the impression everyone was looking forward to ARM-15 4core cpus that had 64bit capability, specially the 64-bit addressing for large amounts of DRAM. Well now the first test chip for ARM-15 has been announced. And the timescale for the production release of that chips is now clearer. My only question is when will they announce the x64 version of ARM-15. Let’s first look at what’s been written so far. Read On:
Intel is doing its level best to spread Fear, Uncertainty and Doubt concerning how viable ARM based chips would be in a data center server rack. ARM is the engine of many a cell phone, but server loads? That’s the question Intel is trying to raise even as data center floor space and cooling costs become more expensive. Calxeda is trying to emphasize the lower energy consumption going forward attempting to put a greener face on its potential data center installations.
There have been hints, whispers, speculation and allegations that ARM is setting it’s sights on the data center with it’s ARM-15 CPU architecture (still in development). However, on the mobile computing front, Apple has showed what amazing power savings are possible with fully tweaked ARM-8 cpus in it’s A4 processor for the iPad and iPhone 4. A full 10 hours of battery life in a tablet still stands as a record for all others to break. And yet, no one has quite achieved that level of optimization. Which leads me to wonder what if someone with enough startup money and time could develop an ARM based server TODAY? What kind of power savings could they achieve given what is possible today in a SeaMicro SM-10000 server using lackluster Intel Atom chips designed for netbooks?
