In Rick's case it seems he sent some of true VLARs back to GPU when used "75%" distribution. Can this mode of operation leave VLARs on GPU?

I think this is only possible if Rick has checked the option "Use True Angle Rate" (basicly the tool is then using Eric and Richard's detection of vlar/vhar)
Rsc_fpops_est = 80360000000000.000000 is a vlar
Rsc_fpops_est = 23780000000000.000000 is a vhar
Instead of your detection algorithm (which i assume is also used when doing the vlarkill):
true_angle_range < 0.13 = vlar
true_angle_range > 1.127 = vhar
Greetings,

Raistmer:
Maybe. I never used flop estimates for this purpose cause execution path will based on numbers derived from AR. Science app doesn't know about estimations of its performance ;)

Thanks guys. I typically run the reschedule with VLAR/VHAR to CPU. Being an engineer who can't keep his hands off of things ;D , I then unchecked the box and ran the 75% to GPU. I think I could have tried "true angle" as well.
I tend to play with things to see how they work. I was just a bit surprised when some of the "bad" ones actually ran OK how ever I got them back to the GPU. Of course there was a lot of carnage too ;)
By the way I had about 60 tasks and when I rescheduled using "VLAR/VHAR to CPU" all but 2 went to the CPU. After playing I got about 35 on the GPU. I wasn't paying attention, but I think maybe 10 or 15 ran with the rest dying the horrible death.

Hi,
What about MB application 605? I only have 605 no 603s, so I receive "Error : There is no application defined for version 603".
