Subject [jira] [Commented] (GIRAPH-861) Vertex/Edge loading should be distinctive phases
Date Thu, 27 Feb 2014 20:26:19 GMT


Maja Kabiljo commented on GIRAPH-861:

Which race condition are you referring to? Adding this barrier can slow down some applications
which use both inputs (for example if you have just a few input splits currently other workers
will start loading edges while these few load vertices - this way they'll all have to wait
doing nothing - I was even thinking about improving this so that we can have vertex and edge
input threads at the same time so we wouldn't waste anything).
