[jira] [Updated] (SYSTEMML-1427) Incorrect worst-case and parfor memory estimates in special cases

     [ https://issues.apache.org/jira/browse/SYSTEMML-1427?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Matthias Boehm updated SYSTEMML-1427:
-------------------------------------
    Description: 
This task aims to fix the following miscellaneous issues of worst-case and parfor memory estimates: 

1) Incorrect handling of incomplete worst-case estimates (can result in negative memory estimates)
2) Incorrect parfor estimates of operations with spark execution type (handled as forced execution type)
3) Incorrect parfor estimates in case of constrained optimizer with unspecified degree of parallelism.
