FAH has COVID-19 projects

Yeah...my PPD is minimal since they got all of this publicity. I'm keeping those resources busy through BOINC though. I have the BOINC client set up to pause GPU work once I have FAH work units to process.

this just keeps going nuts. Current flops of the F@H network is 1.5 exaflops, a few days ago it was 470 petaflops

My boss tried F@H for the first over the weekend. He's like I now understand what the hell you were talking about at the Friday morning meeting about computing power and Covid19. I think he has 3 rigs going full time. 2 in the office and 1 at home.
 
Since im home for 2 weeks i have my main rig doing F@H for CPU and GPU. With the project number i was able to see my first GPU WU was for COVID-19.
 
I'm baaaaaccccckkkk

gonna get a couple more boxes up, lets see how it goes
 
I just installed the client on a box with 40c/80t can we not assign more than 32 cpus to a project?
 
well it has assigned 32 (config errors if you put more than 32) and finally got a WU, and is using 40% of the CPUs as expected... so I may just put another 32 core CPU instance and a 16 CPU instance to use all 80 threads

edit:

seems it doesn't utilize threads only cores?

When you aren't using all threads, windows will assign 1 per core before doubling up to maximize performance.

There are units that can use more than 24t, though there are many that cannot. I am currently running one at 128t. The servers are in pretty rough shape right now due to load, so it probably isn't assigning the best units to your system at the moment.

Edit: Since your chips are 10c/20t I would do in multiples of that. I would probably start with 4 20t or 2 20t to start with.
 
so what would be the best configuration in this case?
 
I snuck in an edit - I would recommend multiples of your socket core count.
 
how would I do that though if the client won't let me assign more than 32 CPUs?
 
Running my new build so far. Finally running on the Prime X570-Pro board with a R7 3700X CPU. This thing just chews on this work. I did run PBO for a day but I was not to happy with the high temps and not much of a gain in speed. I think I ran about 10° C hotter for about 250mhz in clock speed. However the reds in the power usage bar went away when using the PBO. Anyway, Folding the [H]orde.

Wow, I wonder if that is a Windows bug. I've never seen that before.

Edit: I'll ask.
 
Ref my EVGA post, i think that may have been due to either WU size or the a4 core that was in use at the time.

As for FLECOM's error Sorry, i can't help with windows, my 2p is on linux. I haven't pushed it beyond 20 threads due to the lack of WU, since we are going into lockdown on sunday I guess I now have something to investigate on my day off!

Glad to see you bring some firepower back online. I'm only able to bring a couple of instances back now, myself. But it's still something in the overall scheme.

lucky you, my current output is around a third of what it should be

It must have been all my bad luck leading up to it - I was struggling to even get a single WU it seemed like for awhile, but it's gotten better the last 2 days. I just checked and I have a machine sitting idle waiting on a WU again, though.

no problem, I can move it over to linux next week, box was a spare so it's not doing anything else anyway
 
Anyone seeing errors like the following?

I had to move my work directory aside and let the device download new WUs. It was failing like this over and over.
 
Yep, that's the wrapper not being smart enough to catch a thread count that is incompatible with that specific simulation. In the future if you get one of those you can reduce the thread count until it starts folding. I'll report that so they block 24t in the future.
 
Getting back into this for the first time in years has prompted some upgrades to deal with cooling and noise:
  • be quiet! DARK BASE 900 case
  • be quiet! DARK ROCK 4 CPU cooler
  • Arctic Accelero Twin Turbo III cooler for the GTX 1070
Doing Rosetta when F@H doesn't have work units available, trying to alternate every day.
 
Update: Installed everything and wow, this case is quiet! I hear a low hum at most. CPU temp dropped also, average was 75C now low 60C range on folding load.
Unfortunately I must have messed up the GPU install since F@H causes a hard shut down doing GPU folding. Running Unigine benchmark puts my GPU at 95C but doesn't cause a shut down. So, I have some new Grizzly thermal paste and some aluminum heatsinks w/thermal tape that arrived today. Going to spend some more time on Youtube videos to see if I can get the GPU cooling straightened out before going back to F@H.

In the meantime I've been cranking out Rosetta and don't even notice. The be quiet! gear was $$$ but worth it.
 
Hello everyone from another oldtimer!

I fired up the new client on my Dell XPS 9570 laptop to contribute for the COVID-19 fight. I'm pleased to see a few old timers coming back as well like FLECOM :D
 
Isn't it normal that the v7 FAH web control show 1,730,491 points earned when in the FAH stats for mine, it's 34,142,115 ? If I check for team stats, it display correctly and I wondered where is the issue
 
I initially didn't install the GPU cooler correctly and had hard shutdowns when GPU folding (hitting 90C) had to stop for a while. Finally got some Grizzly thermal paste and some aluminum heatsinks and reassembled, fodling quite nicely now. At 58C under GPU load now and stable. The orientation of the GPU in my case makes me wonder if the aluminum heatsinks are going to fall off, the thermal strips don't strike a lot of confidence in me. I might have to look in the case again to see what might have fallen off, may need to skip the thermal tape and go with thermal glue.
