[jira] [Commented] (GIRAPH-1165) Skip iterating through vertices in
supersteps with just global logic
[ https://issues.apache.org/jira/browse/GIRAPH-1165?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16243070#comment-16243070 ]

GIRAPH-1165: Skip iterating through vertices in supersteps with just …
…global logic
Summary: Some supersteps don't do anything with vertices but just do global worker or master computation or perform aggregation. Not iterating through vertices in these cases can save time.
Test Plan: Ran some jobs with supersteps which only do global computation and verified computation is skipped and we save a few seconds per these supersteps
