[jira] [Updated] (SYSTEMML-2030) Missing transpose-matrixmult rewrites for special case mixed exec types

     [ https://issues.apache.org/jira/browse/SYSTEMML-2030?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Matthias Boehm updated SYSTEMML-2030:
-------------------------------------
    Description: For example, on L2SVM 800GB sparse, there are various examples of {{t(X) mm y}} where we do not apply the transpose-matrix mult rewrite to {{t(t(y) mm X)}} because the matrix mult is of type CP whereas the transpose is of type Spark.  (was: For example, on L2SVM 800GB sparse, there are various examples of {{t(X) %*% y}} where we do not apply the transpose-matrix mult rewrite to {{t(t(y) %*% X)}} because the matrix mult is of type CP whereas the transpose is of type Spark.)
