Re: [phenixbb] reduce hangs

Dear all, I'm not sure how much of my conversation with Jeff Headd and the comments from others that I received made it onto the mailing list. The problem with reduce being stuck in an infinite loop and refinement never completing has now a workaround, if no solution: Mark van Raaij pointed out that running refinement repeatedly while varying the number of cores would eventually avoid the infinite loop. I didn't observe that, but while running refinement with a handful of Xeons got stuck, running the same job with the same executable on the same OS with a bucketful of Opterons instead succeeded. As I said, there's no solution but a number of ways to get unstuck if you find yourself in the same situation like Mark and me. Best.

My guess is that it's down to slight floating point differences in the coordinates throughout the course of refinement, but it's so hard to pinpoint. If you have access to other machines it is probably worth trying. <snip> Jeff
