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

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 ...

Apart from inherent performance characteristics, locality also has a role (L1 is closer to the CPU). According to What every programmer should know about memory: It is interesting to note that for the on-die L2 cache a large part (probably even the majority) of the access time is caused by wire delays. This is a physical limitation which can only get ...

No, they're not the same type of RAM, even though they're on the same chip that uses the same manufacturing process. Of all the caches, the L1 cache needs to have the fastest possible access time (lowest latency), versus how much capacity it needs to have in order to provide an adequate "hit" rate. Therefore, it is built using larger transistors and wider ...

L1 is usually used as a storage for decoded instructions, while L2 is a general cache for a single core. The lower the cache the smaller size it is and faster it usually is. As a rough rule of thumb for PC processors: L1 Cache: 2-3 clock cycle access L2 Cache: ~10 clock cycle access L3 Cache: ~20-30 clock cycle access The design of the L1 cache ...
