Self-wiring Supercomputer

redcone writes "New Scientist is reporting on an experimental supercomputer made from Field Programmable Gate Arrays (FPGA) that can reconfigure itself to tackle different software problems. It is being built by researchers in Scotland. The Edinburgh system will be up to 100 times more energy efficient than a conventional supercomputer of equivalent computing power. The 64-node FPGA machine will also need only as much space as four conventional PCs, while a normal 1 teraflop supercomputer would fill a room. Disclaimer: At this point in time, the software needed to run it, which is the key to the project, is vaporware. "

some resources

the wikipedia article on FPGA: http://en.wikipedia.org/wiki/FPGA

great list of resources from WP on FPGA if anyone's interested in reading more:

• comp.arch.fpga Google archive of Usenet groups, where people interested in FPGA hang out.
• Opencores A set of free IP cores that can be implemented in FPGAs
• Comprehensive tutorial on FPGA
• A comprehensive list of FPGA CPUs
• A good FPGA tools overview
• FPGAworld news, jobs, forums, demos etc.(http://www.fpgaworld.com)
• FPGA Basics by Ray Andraka
• Fpga4Fun various fpga projects
• FPGA Boards
• AP100 PCI Platform FPGA Development Board
• Information about signal processing on FPGA by RF Engines
• FPGA manufacturers
  • Xilinx Xilinx has traditionally been the FPGA leader. Their general philosophy is to provide all the features possible, at the cost of extra complexity.
  • Altera Altera is the second FPGA heavyweight. Their philosophy is to provide the features that most people want while keeping their devices easy to use.
  • Lattice Lattice's focus is on low-cost, feature-optimized FPGAs and non-volatile, flash-based FPGAs.
  • Actel (http://www.actel.com/) and QuickLogic have antifuse (programmable-only-once) products.
  • Cypress
  • Atmel
  • Debian FPGA.

Some bits of information

Once the 64-node machine is built, the designers will try to transfer several existing supercomputer programs onto the new hardware using these tools. "If we can get these [programs] to work, we'll know that we have a general purpose solution," Parsons says.

[Emphasis added]

So, this is still vapourware.

LARC, at NASA, built an FPGA supercomputer. Here's a link to a related paper from 2002. Note, its a PDF.

Additionally, Cray builds an FPGA using supecomputer in its XD-1. It's definitely a nonvapourware project since they've sold over 15 of them. Yes, yes, it also uses Opterons, but they're paired with FPGAs.

Additionally, prior to Seymour Cray's death at the hands of a drunk driver, he was looking into FPGAs as his next stab at supercomputing.

Existing products: Starbridge Systems

There's a company that has been selling this type of system for a couple of years.

They also have their own language called Viva to be able to program the computer.

Hi mum, we're on slashdot :)

[AndyGasman]

Ah, the fame and fortune...

As a software design engineer at Nallatech, I'm pretty chuffed we came up on Slashdot.
Not wanting to come across as a pedant...

"software needed to run it, which is the key to the project, is vapourware"
This is not the case, with Nallatech's software is capable of providing the intercommunication (DIMEtalk), the low level control (FUSE) and the Algorithm implementation (double and single precision floating point cores, as well as a new tool, currently in beta, to simplify their use by developers).

"Nallatech, a company that makes software tools for FPGA programmers".
This is true, however we do equal amount of hardware and firmware development.

More info:
Read our white paper about supercomputing for the oil and gas industry, reg required I'm afraid?
The foot print of this thing could be tiny, as you can get 9 Virtex 2 pro FPGAs (Using BenBLUE-3 modules) on a BenERA Carrier card, and you can get 4 BenERAs into a cPCI rack, so to get 64 FPGAs you just need 2 standard cPCI racks. Since you can get 4 cPCI racks into you standard 19" server rack, which would kick out a massive 2 Teraflops.

Though, I can't help but think Cell processors might kick our asses, at least a little bit anyway. Sorry about all the links to Nallatech, just pointing folk to the info. Oh, by the way, I think the 1 Teraflop for 64 FPGAs is a very conservative estimate.
