I had some initial discussions with Adapteva and ClearSpeed. The Clearspeed device is a maths co-processor on a PCIe board (e710) or a HP blade server board (e720). They offered to provide a loan pre-production board for software development. Unfortunately they had a pretty hefty price tag and didn't seem too keen on supplying a board at a discount so I never got one. I pointed out we'd need one to support the software and update it so a loan one wasn't the best option. See http://www.clearspeed.com/ for details. Adapteva have a 16 CPU on a chip available. It attaches to an Altera Stratix board and can be connected via USB (and possibly LAN not too sure though). Its known as the Epiphany Multi-core Evaluation Kit. They were working on a lower cost version with their newer 64 CPU on a chip. It was due Q1 2012, which they have well and truely missed but may get something out by the end of this year. They wanted a 5 digit amout for their evaluation kit which includes a software development kit (based on GCC 4.7.0 I believe). See http://www.adapteva.com/ for details. There is also a DRC Accelium Coprocessor available. I haven't investigated pricing on it but suspect it will also come with a 5 digit price tag. It also comes with a SDK which I believe is based upon GCC similar to the Altera. Its available as a PCIe card or as a chip that can be plugged into an AMD Opteron socket. See http://www.drccomputer.com/ for details.
There are other around but they don't appear to be as well developed at this stage. I expect for BOINC to be able to schedule tasks for these/use them as a co-processor then it will need to have some API hooks to detect if its got one or more and the co-processor logic will need a lot more work. Not too sure which of these are going to support OpenCL though, maybe all of them in the long run. All seem to support C/C++ as a initial language offering. Hope this is some use to the community. I will make some inquiries into the DRC Accelium and see how much they want for their PCIe boards and what they come with (software wise).
