So, for these places current choice of sleep(1) is optimal one even w/o high-prec timer activation.
I'll repreat test with -high_prec_timer now for GT720

I see no -use_sleep used.
Is it idle CPU? or busy CPU run?

The same question. CPU idle or busy? Or, maybe, single CPU core free only?
Sleep behavior strongly depends from host load that's I always ask for full description of test conditions.
And for prev run w/o sleep enabled - no explanation why these builds consume much more CPU  :o

Yep 7 cores were in use.

That shows the need of fixed amount sleep in case of underloaded CPU.
GPU app has bigger priority so, if some free CPU resource awailable, it will be scheduled for exection there.
What strange is no differencies in STT and Sleep(0) behavior. From what I read on main forums Sleep(0) should return to the same process immediately so just spin with full CPU busy while STT should give up CPU slice always(wrong, only if there are ready threads on the same CPU). So, in SleepQuantum counter it should have bigger mean value (hard to imagine that with absolute most of 2704 occurencies process was exactly at the end of its current time slice). Nevertheless once can see VERY close mean times (<>) for Sleep(0) and STT. Strange. If so I don't see any advantage of STT at all  :-\
[NB: Windows time slice ~10-15 ms and STT mean is 0.0014 ms]

I have to remove r3500 from this bench  because it doesn`t even start with all cores in use.

Also sleep versions doesn`t even start.
Zero CPU usage on GPU task so i aborted after 5 minutes.
Not even wisgen started.

Please remove all wisgen tasks, run bench, await ~5mins, locate stderr.txt in ScienceApps folder and attach it as is.

Host reseted after 5 minutes.

I told you that before.

Could it be power issues? Maybe more strong power supply needed?

thanks. app processed OK some time, even found some spikes.
