-------------------------------------
Description: On modern servers, with close to or more than 100 virtual
cores, even small serial fractions of multi-threaded operations (e.g., for
thread pool creation, final aggregation, or dense-sparse conversion) can
significantly limit the attainable speedup and thus limit performance. This
epic aims to resolve all related issues for the SystemML 1.2 release. (was: On
