I read about that 18 core Xeon and I thought it was a misprint. My general assumption is that any multicore Intel CPU where the core count is NOT a power of two in really a chip WITH a core count of a power of two but with some cores disabled. Would Intel sell a chip with 14 of 32 cores turned off?bob wrote:They also run these up to 18 cores and 45mb L3.
We also have a "phi" board in this box. 61 cores of what is basically an intel pentium processor (in order execution). I have not yet done any testing on that as our tech guys apparently broke the software with an upgrade. But Linux runs on it and it looks like a "computer within the computer." I log into this 20 core box, then ssh to the 61 core box, which seems strange, but seems to work.
More later. There might be some opportunities here for additional shenanigans, such as using the phi cores to do evaluations and such sort of "belle-like"
Things have come a long way since I used a CDC 6500. It too was a multicore machine -- a pair of CDC 6400s in twelve racks of circuitry sharing the same central memory, PPU ring, and operator's console.
