Implicit Multi Threading (MT)
Means the algorithm can take advantage of multicore processors via OpenMP. "Implicit" means the algortihm itself is not parallelized, but that it relies on parallelized matrix-matrix product rountines.
Explicit Multi Threading (MT)
-
Means the algorithm is explicitely parallelized to take advantage of multicore processors via OpenMP.
+
Means the algorithm is explicitly parallelized to take advantage of multicore processors via OpenMP.
Meta-unroller
Means the algorithm is automatically and explicitly unrolled for very small fixed size matrices.
