I am hoping someone might be able to help:

In the days when I started with computing (C64 and later Amigas) expansion slot cards with co-processing ability were relatively common. I am looking for any modern analogue to this as I would like to build a Multi-CPU and GPU system, therefore I am looking for any information on products similar to this (wayback machine page here), preferably with an AMD CPU?

Any help/information greatly appreciated as I have searched online for quite some time with no real success.

Cheers in advance.

NB: it looks like there may be an update from the original link, which leads to a product that may suit, if anyone else is interested: this I7 PCI card

    \$\begingroup\$ Using GPUs for general-purpose application acceleration is very common, and there are many software tools, both free and commercial, available to help you do this. But this question would be a better fit at Superuser.SE. \$\endgroup\$ – Dave Tweed Apr 4 '14 at 13:22
  • \$\begingroup\$ Thanks, didn' even think about superuser.se. I use GPGPUs already, even from before the advent of opencl etc, and they are quite verssatile, but I now find a need for full fledged additional CPUs hence my question, will post on Superuser however:) Cheers. \$\endgroup\$ – GMasucci Apr 4 '14 at 13:32

PCI express is really too slow for this. You need a motherboard designed to take multiple CPUs. These are available for up to 4 CPUs, although this is not cheap.

I believe the card you linked to is a "single board computer", so I'm not even sure it would work in a normal PC. It's probably designed for connection to a backplane or "mezzanine" system.

You can get "exotic" processors and FPGA add-in cards, e.g.: http://www.nallatech.com/PCI-Express-FPGA-Cards/pcie-287n-7-series-fpga-network-processing-card.html

    \$\begingroup\$ I have used similar cards in the past, still have a 286, 386 and 486 on seperate ISA/ZORRO cards for my Amigas, also have a 486 pci card (ancient and cant remember the make atm, will look it up when I get home) and they work wonderfully provided you either have custom software to utilise them with VMs or are happy to run a single tower cluster compute system:) The card I linked fits in my home PC in a PCIe mini slot too. \$\endgroup\$ – GMasucci Apr 4 '14 at 13:47
  • \$\begingroup\$ Correction PCIe mini should have read PCIe x1 \$\endgroup\$ – GMasucci Apr 4 '14 at 15:23

You may consider using Intel MIC. Quite a few servers for math processing use it.

  • \$\begingroup\$ I like the idea of the Xeon PHI, however it is a full in-chip OS and hardware solutions, running uOS. Not so bad, but my primary aim is to make a PCIe expandable processing system, although I am looking into the PHI as and aside:) \$\endgroup\$ – GMasucci Apr 4 '14 at 15:05
