|[eigen] vectorization of sum|
[ Thread Index | Date Index | More lists.tuxfamily.org/eigen Archives ]
Hi, I looked at general vectorization of redux but this is not very convenient... - in the general case it would be better done as a separate method packetRedux - this would require the size to be a multiple of packetsize even in dynamic case - this is not the same as vectorizing redux when possible (return type is a packet instead of a scalar) - the final reduction step producing a scalar is not available in general, only in the special case of the sum is it available as ei_predux... So instead, I'm now looking at splitting sum away from Redux, and vectorizing it. Cheers, Benoit
