Not yet... I had some guesses, which is why I suggested the processor pinning
and using a ramdisk. But we haven't tried applying all of those to my laptop,
which has 3 core types, or the POWER system, which may be interesting to use a
ram disk on.
I'm curious though, and admittedly haven't tried looking myself yet, about how
the SIMD calls might look across different processor architectures. We'll try
to get that on the POWER system soon...
Regards,
Mark
