Thanks, I meant the cc.config file. Chalk it up to posting at the end of a long week.

Is there a command I can insert into the config.sys file to dedicate a whole CPU thread to GPU tasks (in a multithreaded system) and override the fractional CPU assigned by SETI?

Spinning to 1 G is a laudable goal, but may not be necessary, at least from a physiological perspective. Some fraction of a G may be all that's needed to minimize bone loss and muscle mass deterioration. Unfortunately, 40 years of wallowing in LEO hasn't advanced the artificial gravity issue much. Sure we did studies with exercise programs in 0 G designed to address bone and muscle mass loss (and other issues). But these are not practical solutions for deep space missions with 0 G transfer orbits lasting months or years. Doubling or, in some cases, tripling, your caloric intake for aggressive exercise programs translates into increasing the mass of food consumables. It also would require an increase in consumables like CO2 scrubbers (if using LiOH or some other type of non-catalytic CO2 scrubber). Launching mass costs money.
In his book Journey to the Stars, Robert Jastrow hypothesized a twin module system for a Mars mission, tethered by cables, spinning at a rate to create 0.67 G, This would be midway between 1 standard G and Mars gravity.
Spinning ships/stations/colonies of any kind generates second and third order issues like stable antenna mounts and docking ports, and constant thruster "fiddling" (with associated consumable use) will be necessary to offset the effects of movement inside the ship/station.
I believe the first artificial gravity systems will be designed at some fraction of a G; will be compartmentalized as a small part of any craft; be at right angles to the direction of thrust/travel (in the case of ships), and may not run 24/7. Maybe G in the sleep cycles would prove best.
I still think a variant of the carnival ride Gravitron will find its way into space.

I'm old enough to remember the Pentium 60 processor flaw (pre-SETI). As long as you weren't running nuclear weapon yield simulations, the hue and cry far outweighed the impact.
I too will wait and see.

I'm having an issue with one machine in my stable having open CL file build errors for AP tasks. Other SETI open CL tasks on that system seem unaffected. I can turn off open CL in the config.sys file, but that stops all open CL work for that machine. I abort the AP files as soon as I recognize the build-fail, so my wingmen aren't delayed excessively.

Is there a config.sys line command that will suppress AP files to this particular machine?

My main cruncher (i7 with GTX 970 GPU) has never before had a work flow problem, but I'm sitting on empty:

State: All (324) · In progress (0) · Validation pending (135) · Validation inconclusive (2) · Valid (187) · Invalid (0) · Error (0)

Some of my other crunchers are down to 5 or fewer tasks remaining.

Are you running the BOINC screen saver? I've had problems on some of my rigs with the monitors behaving erratically. I've opted out of the screen savers and it seems to help. But these were legacy rigs running XP or Win 7.

They are still trickling in. I got three yesterday and three more today. All new work, except one which was twice crunched as inconclusive.

Yes, another nice run. My biggest single file credit topped out at 719+.

Who is the keeper of the green stars? I wrote a check to Berkley using the donation form back in May. It didn't clear my account and trickle down to SETI until 16 August.
