Matthias Boehm updated SYSTEMML-400:
------------------------------------
Description: 1) Transpose operations (initially, dense-dense, sparse-dense)
w/ parallelization over rows/cols according to input matrix shape. Despite
significant serial fraction (for result allocation, which might be addressed by
another change), an initial prototype showed already 2-3x improvements for
sufficiently large matrices.
> Multi-threaded reorg operations
