All the screens went off for

All the screens went off for 10 seconds.  I think the driver crashed, I guess the driver was tired, I hadn't rebooted in a month.  Running much better after restarting.  Now I don't know if Einstein's gravity app caused it or not.... it could have been meerkat.  It could have been a coincidence.  It happened just after switching to Einstein.

If this page takes an hour to load, reduce posts per page to 20 in your settings, then the tinpot 486 Einstein uses can handle it.

Or the driver was tired ?  :)  Sometimes software fails "slowly".  Sometimes the diagnosis is a "memory leak".  Anyway.  Rebooting fixes it until someone actually finds the error in the code.

Reboot - n.  Putting your boot back on?  ;)

Windows itself also "fails slowly" and has for a very long time and yes rebooting it can make all the difference.

Perhaps initially when I ran

Perhaps initially when I ran two gravities at once, maxing out the VRAM for a day annoyed the driver or windows.  I'll stick to one on this machine.  The machine with 4GB VRAM which only runs Boinc is ok with it.

It's being slow with Asteroids on the GPU aswell.  Maybe I'm overloading the CPU?  Maybe too much Arecibo is a problem....

If your CPU percentage is above 80-90% on the Windows task manager that certainly might be an issue.  I know on my 5700G Win box it has been.

 

 

Could be a bit off topic but I've been crunching WCG at 100% on my cpu recently. Well I dialed it back to 95% to free up some threads and ran Einstein@Home. Well 3 times after a period of time (couple of hrs) my pc crashed and the red light was on the motherboard to suggest a CPU error! I found that quite bizarre as none of my other pc's had this issue.

I suspended the cpu crunch and just ran E@H by itself and the issue stopped. I'm now running the cpu @ 50% and still had no failures so i can only assume that not enough threads were being reserved and my cpu had a dummy spit. At least it wasn't a total failure! 

Right now though, I think I might be missing something. I can't even get 1M/day with any of my cards (4070ti, 3070ti, Radeon VII) running Meerkat. The 4070Ti tested as 1 wu= 7min, 2 was 12min, 3 was nearly 18min, 4 was 23min, 5 wu = 31min.  

I think the Radeon VII is getting old as I see I have a driver error message pop up a lot. (Only running 3 tasks at a time)

One thing could be the 32gb of ram in the pc, if you are running nearly every cpu core and 3 gpu tasks as well you could be running out or regular ram for the pc to do it's thing, especially if you use the pc for anything else as well.

Chooka,If you run the

Chooka,

If you run the boincmgr at 95 percent and use max_projects to restrict your CPU crunching to a thread count that makes enough threads available for GPU crunching you should have a stable setup.

Just looked at my last All Sky GW under windows run with a rtx 3080 ti. At 3x it looks like 1.5M might be possible.

Hi guys, I'll check the

Hi guys,

I'll check the RAM idea thanks Mikey!

 

@Tom - yeah I'm pretty sure that as I add more gpu tasks, boinc automatically halts cpu work tasks to free up threads. So far it looks like all I can achieve with a 4070Ti is 700 credits/day. Seems low. I am only trying Meerkat at this stage though. I'm also using my CPU so maybe I'm losing some time there. Not sure. 

 

I've reviewed the top 50 pc's and mine are way off across all cards :/

Just doing a little testing

Just doing a little testing with Meerkat and my 4070Ti

 

1wu = 360sec/wu (speed up by about 10sec/wu if I suspend all cpu crunching) 

2wu = 330sec/wu

4wu = 337sec/wu

 

Maybe I should just keep adding wu's?

As long as you have memory on the GPU maybe yes.  I saw a large slowdown when my gpus started running 98% of the available GPU memory.  But 80% plus was not an issue.

I expect you can get the same kind of performance with the 10,000 point tasks from O3AS aka: All-Sky GW.  At least 3x should be possible.  And will drive your rac up considerably.
