[jira] [Updated] (SYSTEMML-591) Consolidate replicated compilation chain
[ https://issues.apache.org/jira/browse/SYSTEMML-591?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Arvind Surve updated SYSTEMML-591: -- Sprint: Sprint 4 (was: Sprint 3) > Consolidate replicated compilation chain > > > Key: SYSTEMML-591 > URL: https://issues.apache.org/jira/browse/SYSTEMML-591 > Project: SystemML > Issue Type: Task > Components: Compiler, Parser >Reporter: Matthias Boehm >Assignee: Deron Eriksson > > With the addition of APIs and tools, SystemML's main compilation chain has > been replicated multiple times (main, jmlc, mlcontext, debug). This > redundancy creates really a maintenance hazard as shown by recent changes. > This task aims at consolidation by providing a configurable compilation chain. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
[jira] [Commented] (SYSTEMML-1811) Can we Implement X%*%t(X) in a better way?
