Matthias Boehm updated SYSTEMML-1976:
-------------------------------------
Description: Recent ALS-CG experiments with the ultra-sparse amazon reviews
dataset (sparsity 1.2e-6) have show unnecessarily slow codegen outer
(especially left mm) operations. This task aims to fix this by better cache
blocking to ensure blocking itself does not introduce overhead for ultra-sparse
matrices.
