For your information:
I'm crunching a NOELIA_smduplicate workunit, and it's running at 75% GPU usage. (on a GTX 680, Core i7-980x)
I guess this is a new batch, and it's normal that it has lower GPU usage than usual. (The other workunits running at 97-99% GPU usage.)

Me too! At least the GPU gets break running at 58 degrees C.

I hope it completes successfully!

Same thing here too, it jumps between 75% to 77% on my GTX670. I noticed that the card runs at a solid 1201MHz on its own. It has an open ended clock boost and usually runs at 1150MHz when at a 98-99% GPU load.

Hi guys!!

This workunits are exact replicas of the so called wu's smd and smd2, sent a few weeks ago. no changes were performed, is just a prolongation of these simulations to have more material to work with.

Hi Noelia!

These smduplicate workuntis use less than half CPU time as GPU time, while other workunits use the same CPU and GPU time.
(for example: 1, 2)
So these workunits use the CPU less than others, maybe that's why these workunits can't feed the GPU as much as the others. (I guess it's true for the GTX 6xx series only)

I have one (NOELIA_smduplicate) on my GTX 560Ti right now and it can't get over 83% GPU usage, it jumps around from 76% to 83% using 0.597 CPU usage compared to 0.682 CPU usage on all other wu's. I suspect that each card is slightly different, those are the numbers for this particular card.
