Message 69834 - Posted: 19 May 2020, 2:02:56 UTC

In the last day or so, I've noticed tasks finishing much more quickly. I have four AMD Radeon 280X cards, and they used to finish them between 1 minute and 1 minute 15 (running two per card). Now I'm seeing them at as little as 40 seconds.

I have moved cards around between computers, but as far as I know I've done nothing to warrant this speed increase. Did the program get made more efficient, or have I broken something? I'll keep an eye out to make sure they all validate.

What CPU was in the old one compared to the new computer you moved them to?

I've moved them between four computers. One is a Q8400, one is an N3700, and two are dual Xeon X5650s. Doesn't seem to be the computer that causes the speed increase, rather random tasks that run quicker, perhaps some are shorter? All seem to be validating ok. I always make sure the computer has spare CPU power so it never throttles the GPU.

Not all tasks are the same. You got a bunch with an easy parameter set compared to what you crunched before. So they take less time to crunch.

I know there are at least two types - the bundles of 4 and the bundles of 5. Plus there are some marked test and some not. But I've never seen them run that quick before.

If the condition persists, count your blessings and see if you can figure out if you made any changes to the host to account for this new behavior. Then publish for the rest of us to copy. LOL.
