You'd think an article called "NASTY RUMORS ABOUT MAXDOP" would have something to do with Britney Spears or maybe Robert Downy Jr, but in that case it'd be total fiction (at least, it would be coming from my pen). So, I was en route to the 2008 Microsoft MVP Summit yesterday and I had a chance to catch up on my reading. You may have heard some rumors that you should only ever set MAXDOP (maximum degrees of parallelism) to an even number. I can neither confirm nor deny these rumors since I haven’t had time to test this yet myself. But I’m curious if any readers out there have definitive information one way or the other. Evidently, there are two roles involved in parallel processing, a writer and a consumer. Naturally, when two roles are at work, the MAXDOP setting doesn’t have to share resources when it is set in increments of two. Hope this helps, -Kevi
