GFN Jade

My estimations of the expected number of GFN16 tasks to find a prime must be way off since I am still empty on primes. Hopefully I will finally hit one during February.

Personally, I really like the current format.

Yay! Found my first GFN-16:

71083738^65536+1

Took me 26,425 tasks to find. I sampled 6,022 of these tasks and 2,705 were firsts, 44.9%.
From sub-project status page takes Average of 15,056 WU/Prime for GFN-16.
I had performed 78.8% of the tasks needed on average to find a prime.
So I was a little bit luckier than average.
Now moving on to GFN-17-Low.

Congrats! I’ll hopefully find my first soon as well. If you look at the recent prime finding rate though, I think it is substantially lower than the average rate you backed out from the project page, although maybe that is just a task/WU difference I am not accounting for between the project page and the prime/task stats.

Looks good to me. I'll finally get to participate in a TdP too!

This will be the first one where I have a chance of getting the new participation badges. I was really disappointed that they weren’t awarded retroactively. They get harder and harder to get each year with the same compute power. I’ve been doing calculations, and with my current compute power I only have a 50% chance of finding a prime that qualifies for the top list during the month.

Personally, I think SGS should either be swapped for a different project, or SGS advanced to a larger range.

It’s not idling or loading webpages or anything like that. The task manager explicitly says that primegrid_cllr.exe is using 16.6% CPU instead of 12.5%.

In an effort to be nice to my wife's ears and decrease the fan noise from one of my computers, I have been trying to run less on it than it is capable of. The computer has a 9700k in it, and I have set ncpus=6 in the cc_config.xml.

I've noticed that when running PPSE with a single thread set in the PrimeGrid preferences that the Windows Task Manager shows each of the primegrid_cllr.exe processes using 1/6 of the CPU. I would expect each one to only be using 1/8 of the CPU since I have set them to use a single thread in the preferences.

Does anyone know where the extra CPU time is going?

When I saw this post, I hoped it was the reverse of what it actually is. I was hoping it was a way for someone else to use my home computer to run their projects for a small fee (which would have to be less than cloud providers to not be exploited). As someone who lives in an area with very low electricity cost, this would be attractive to me and then I would feel less bad about leaving my computer on 24/7 crunching things. Of course, you would also have to have the fee be associated with families of processors, and have requirements around stolen CPU time, etc.


You could do this on your own thru PayPal or something with a user giving you their user name and password and you crunching for them for x number of days for y cost. Alot of trust between people going on though would probably prevent some people from doing it.

I can see the OP's way of doing it though for challenges and other short term things. I could boost my crunching power for 2 weeks for example.

Which is why a coordinated marketplace would be much more attractive. When most of what you need is CPU power, why necessarily bother with a cloud provider when you can distribute the cloud over the world and create a true marketplace for compute resources? Potentially a project for me to put together once I retire.

I’m glad I was crunching ESP during this period of time, but am sad that I missed out on this find. Maybe the next one.
