[jira] [Created] (SYSTEMML-1142) ParFor execution crashes bc of singlethreaded warning in LibMatrixDNN

Felix Schüler created SYSTEMML-1142:
---------------------------------------

             Summary: ParFor execution crashes bc of singlethreaded warning in LibMatrixDNN
                 Key: SYSTEMML-1142
                 URL: https://issues.apache.org/jira/browse/SYSTEMML-1142
             Project: SystemML
          Issue Type: Bug
          Components: ParFor
         Environment: ParFor Spark on Cluster with DeepLearning usecase
            Reporter: Felix Schüler


When using functions from the LibMatrixDNN in a Spark ParFor block an exception is thrown by the function `warnSingleThreaded()` due to single threaded execution of functions such as conv2d. 

Disabling this warning resolves the crash but I am not sure this is the right way to go there. The question is also why this executes with one thread only and how to improve here.
