corepointer opened a new pull request #924:
URL: https://github.com/apache/systemml/pull/924


   This PR adds initial cuda codegen support; stays marked WIP until the tests 
in CellwiseTmplTest run fine.
   What works: 
   - dense cellwise codegen with non-vectorized functions (LibSpoofPrimitives 
not ported yet) and without aggregation
   
   ToDo and known bugs:
   - support functionality of LibSpoofPrimitives
   - handle sparse data
   - fallback to java in case no gpu is present
   - aggregations
   - fix a bug where the test system stays forever in wait() on the test thread
