Subject [jira] [Commented] (GIRAPH-504) Create ComputeContext
Date Wed, 06 Feb 2013 04:05:14 GMT

Eli Reisman commented on GIRAPH-504:
------------------------------------

So this replaces the WorkerContext on a per-thread instead of per worker basis, and just does
what worker context did? That sounds reasonable. If WorkerContext is published to end users
without us providing thread safety, thats not good.

> Right now we have WorkerContext which is accessible from vertex.compute, but it's not
thread safe - usually if we want to use it with multithreaded computation we have to use synchronization.
Instead we can create a ComputeContext, which is going to have one instance per compute thread.
