Will the credit per unit remain the same? (please say yes!)

We'll probably increase the workunit size and the credit proportionally (meaning 3x workunit size -> 3x credit per workunit). Not set in stone, though.

So basically computation time remains constant and credit is multiplied?

import os.path !apt-get update !apt-get install boinc boinc-client !cp /usr/bin/boinc /content !cp /usr/bin/boinccmd /content if not os.path.exists('/content/slots'): !mkdir slots if not os.path.exists('/content/slots/0'): !boinc --daemon --attach_project "http://www.primegrid.com/" "account key here" else: !boinc --daemon !boinccmd --set_gpu_mode always !tail -f stdoutdae.txt


This helped me so the GPU wasn't timing out all the time :)

This one worked for me, but I'm only getting around 6hours per week.

Um so could the challenge be extended?

So do you throttle the workunits being sent to that person based on their pc having problems?


No. We put an indicator on the task so that they can see there's a problem and, if they want, fix it.


I've seen one of those while overclocking my cpu, it's a good indicator of whether the overclock is stable.

Um a bit late for a suggestion, but could the SoB challenge be extended to 15 days?

When I'm reading the graph I found that the times aren't put in AM and PM, so there would be two '2020-12-22 04:00's in a graph. Could that be fixed?

Yes, it looks like this:

Would be better with 01:00 - 07:00 - 13:00 - 19:00.

I thought it was using 24hr time for the display too.. I was wrong, but it should now be fixed :) Just had to swap hh to HH.

Oh okay, thx!
10) Message boards : Generalized Fermat Prime Search : GFN CPU task L3 Cache size? (Message 146976)
Posted 273 days ago by Profile dannyridel
Is there any published L3 cache usage for GFN CPU tasks, like LLR tasks publish their memory usage?

fma/avx/sse4/sse2 transforms, GFN-n: 2n * size of FP64
    GFN-21: 16M

fmai/avxi/sse4i/sse2i transforms, GFN-n: 2n+1 * size of FP64

    GFN-16: 1M
    GFN-17: 2M
    GFN-18: 4M
    GFN-19: 8M
    GFN-20: 16M


Ahh that explains why GFN20's on a 3800xt takes 6 days when running 8 concurrently and 2days when running 2 concurrently.
