Matthias Boehm updated SYSTEMML-2053:
-------------------------------------
Description: With the introduction of large dense blocks >16GB, the
memory-efficient dense-sparse conversion into CSR format might overrun the
maximum number of nnz. We should conditionally fall back MCSR if the number of
non-zeros is larger than 2^32.
