Anyone feel like SIMDifiying [arraycopy] (hint hint ;). I suppose vasp is a SIMD version of [arraycopy].
SIMD doesn't help in copying data. And in any case, introducing platform dependend code
is it? Linux Windows Macosx all run on x86 anymore, and GCC works great on each. i never understood this argument against SIMD. im thinking Miller just wanted PD to be slow :)
