Since Athlon XP's do not have the SSE2 (double-precision floating point) instructions, it would make sense to assign these only to Intel cpu's, but I am not sure this was the case. All of my Intel machines are running WinXP, all my Athlon machines are running Linux, so I don't know if these WU's have been assigned only to Intel cpu's, or NOT assigned to Linux machines.
Athlon 64's have SSE2!
That's why I said "Athlon XP's", but thanks for the clarification.
I'm not sure that SSE2 *is* double-precision? I thought that it was just an "extension" of SSE i.e. more instructions? And I thought that I had read that the x87 (floating point) processor was *higher* precision than SSE/SSE2 -- and we all know that Athlon's kick the P4's but in x87 calcs!
I'm out of my depth here, but the DGromacs do use the SSE2 instructions, so they must be related. Are Athlon XP's getting any DGromacs? If so, how are they handling them?
