2f5b7a199b Reworked the threadpool cancellation mechanism to not depend on pthread_cancel since it turns out that pthread_cancel doesn't work properly on numerous platforms. 2016-12-09 13:05:14 -08:00

e3f613cbd4 Improve performance of row-major-dense-matrix * vector products for recent CPUs. 
This revised version does not bother about aligned loads/stores,
and rather processes 8 rows at ones for better instruction pipelining.

6a5fe86098 Complete rewrite of column-major-matrix * vector product to deliver higher performance of modern CPU. 
The previous code has been optimized for Intel core2 for which unaligned loads/stores were prohibitively expensive.
This new version exhibits much higher instruction independence (better pipelining) and explicitly leverage FMA.
According to my benchmark, on Haswell this new kernel is always faster than the previous one, and sometimes even twice as fast.
Even higher performance could be achieved with a better blocking size heuristic and, perhaps, with explicit prefetching.
We should also check triangular product/solve to optimally exploit this new kernel (working on vertical panel of 4 columns is probably not optimal anymore).
