Hi guys,<div><br></div><div>I&#39;ve been working hard on the ART frontend. Lately, I&#39;m to the point where I&#39;m playing around with more complex datasets that are taking much longer to project - so I&#39;d really like to to start using the parallelization engines. I&#39;ve tried Sam&#39;s workshop parallelization demos, and they all work. But launching with the ART frontend (<a href="http://paste.yt-project.org/show/2152/">http://paste.yt-project.org/show/2152/</a>) spawns many independent processes which evidently are not actually splitting the projection job, but still taking up lots of processors. </div>
