Matrix factorization on gpu
http://gamma.cs.unc.edu/LU-GPU/lugpu05.pdf Web(1) On a single GPU, MF is inherently sparse and memory bound and thus di cult to utilize GPU’s compute power. We optimize memory access in ALS by various techniques including reducing discontiguous memory access, retaining hotspot variables in faster memory, and aggressively using registers.
