downloading 340.52 now, and i'm back to crunching

Some users have had trouble with 340.52 and the r2399 OpenCL NV AP v6 app in the v0.42 installer, it's working well for others. See the NC thread A word of warning about Nvidia driver 340.52.

Then I would suggest -cpu_lock option instead as enabled by default in aistub and installer.
I'll test this suggestion in next few days. Maybe this should be default mode for stock too, will see.

Makes sense. Like you, I want to make minimal changes possible for the interim v0.42 installer, so there'll be no behavioural change in v0.42c for people to get used to, but I think it's a discussion worth having between v0.42 and v0.43

LOL.

We'll teach them software yet!

Will it free core when single instance runing?


Not unless we go all the way up to 1.00 - which I think is possibly (but open to discussion) overkill for general users. And if we do that, we consume a whole thread of CPU for each and every AP in progress - which, again, I think is a bit over the top. Not every user is a hardcore optimizer! (and those who are, can look after themselves, as always).

You mean like Mark and Juan ?

That's really good news on the blanked task runtimes - worth all the effort.

One of the ways we could approach the CPU core release generically, rather than by expecting people to make manual adjustments post-installation, would be to increase the CPU usage value in the AI stub. Remembering that BOINC will allow over-commitment of the CPU by any fractional amount up to 0.99, I'd suggest we use a fraction above 0.50, but below 0.99.

For example, I tend to use 0.67. That means that if two AP tasks run together, BOINC automatically releases one extra core - three tasks, and it's an extra two, but it's still two with four tasks running. There's no exact science behind that choice, just a gut feeling (and I don't usually run AP anyway), but it's an approach we have time to consider and fine tune before the live release (I hope).

I experienced the same.
On CPU higher blankings result in shorter run times whilst on GPU processing times dont differ much on my fast GPU.
But it depends whats running on the CPU.
On my FX running APs on CPU and GPU at the same time slows down GPU a little bit ~500 seconds.
