AnandTech – ARM & Cadence Tape Out 20nm Cortex A15 Test Chip

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:

$1,279-per-hour, 30,000-core cluster built on Amazon EC2 cloud

Since the rise of Amazon first as an online retailer, second as a Data Center innovator people have always been surprised by their success. They came to dominate in 2 fields somewhat loosely related to one another. But it’s the second wave of Amazon as a Data Cloud service provider that interests me the most. It’s one thing to provide a service, a whole other to provide an raw infrastructure that you are willing to loan out on an hourly basis. To me that is a really new New Thing and deserves some attention. Here now is Scientific Computing by the hour. Read On:

David May, parallel processing pioneer • reghardware

Exotic chip architectures are always interesting because they tend to be designed to fix a very particular problem. The transputer was designed to be general purpose enough that you could get it to solve a variety of problems as long as you had the chops and the development tools to do it. It was in its day a massively parallel computer in a single chip.

From Big Data to NoSQL: Part 3 (ReadWriteWeb.com)

While I am not a DB admin, I do appreciate the wealth of new database projects spawned by the likes of Google’s MapReduce/BigTables architecture. Similarly the non-traditional Nonrelational DBs are also very interesting and prove that there’s always a right tool for the right job. Though some programmers and developers will continuously try to hammer each nail with MySQL, there options for them are increasing. Whether it’s scale, load, malleability there’s a NoSQL/NewSQL product that will do the job.

Tilera routs Intel, AMD in Facebook bakeoff • The Register

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 pushes Atom smasher to 768 cores in 10U box • The Register

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!

NoSQL is What? (via Jeremy Zawodny’s blog)

Great set of comments along with a very good description of advantages of using NoSQL in a web application. There seems to be quite a bit of philosophical differences over whether or not NoSQL needs to be chosen at the earliest stages of ANY project. But Jeremy’s comments more or less prove, you pick the… Continue reading NoSQL is What? (via Jeremy Zawodny’s blog)

Apple patents hint at future AR screen tech for iPad | Electronista

A lot of Augmented Reality today is centered on software developments running on smartphones. Whether they be Android or iPhone doesn’t matter they want those wonderfully powerful embedded computers available to do all the work onboard the device itself. But, what if the device was not required to do all that heavy lifting itself. What if it off-loaded that work to a data center in North Carolina and beamed back the results to your device?

ARM daddy simulates human brain with million-chip super • The Register

Many wondered when this day would come. Many have written and researched and made full on attempts to simulate the brain in silicon. Now with the rise of low power CPUs (Atom,Arm), massively parallel and dense servers (Seamicro,Calxeda,Tilera) it’s time once again to take a stab at it. Luckily this time around one of the guys who designed the ARM cpu is the Principle Investigator. Something big is going to happen I suspect.
