They will be eventually manually validated, don't worry about them. Somehow during the GMT 13:00-
13:30 timeslot any wus uploaded to server go into validation dormant mode. Admin is aware of it.

Due to the complexity of the sievers coding there is no plan in the near future for an Android version.

I recommend running both 16e Lattice Sieve (small lasievef_small and lasieve5f/V5) as a mean to manage your memory requirements. The small will use less than 1GB of memory.

You can also go to the boinc client settings and force it to only use X % of the CPU cores.

Integer put in standby by our operative Sean. Once Greg wakes up he will sort this work distribution. We apologize for this inconvenience.

For the challenge participants, if you see any anomalies please post on this thread.

On boinc manager client increase the memory usage up to 98%.

I suggest to concentrate on on both 16 (quicker and higher credit payers) for now, eventually those Wu's erroing out will be done by Linux users or they will be cancelled by the server after 4 errors.

Have warned team. We apologise. Feel free to abort them or untick the 14e application.

Welcome Timbo. I'll make sure the NFS@Home feeders are aware and your thread is now sticky.
13) Message boards : Questions/Problems/Bugs : No 15e Lattice Sieve for smaller numbers Tasks for a While Now
Message 2423

I'll need to check with the guys running ECM on the background, I know they were struggling to find work to feed 15e small queue, however I recommend crushing for 16e v5 and 16e small, specially the former where there is still a lot of Cunningham integers to factor. Would be nice to have a nice boost to 200k Wu's per day in there.

BTW, not sure if noticed but it was recently released an update for sub projects apps for CPU's able to run avx512 instructions, but only for linux at the moment. This will give a nice boost.

Back to normal here, just aborting the ones with the highest estimate time. Back to 100% on 16e small, background feeders need some push in there, lots of integers to factor.

If you have spare memory per thread core I recommend just allowing for 16e Lattice Sieve V5 tasks until Greg sorts this out on his end for the 16e Lattice Sieve for smaller numbers aka .lasievef_small.

Under preferences:

lasieved - very small numbers, uses less than 0.5 GB memory, work may be infrequently available: no
lasievee_small - small numbers, uses up to 0.8 GB memory: no
lasievee - medium numbers, uses up to 1 GB memory: no
lasievef_small - large numbers, uses up to 1 GB memory: no
lasieve5f - huge numbers, uses up to 1.25 GB memory: yes

Now I'm getting the same issue. This happens with all Wu's with a completion forecast higher than before. It changed from 28 mins to 2h on my case. So on my queue I have a mix of the two. Do we need to rerun the computer Benchmark?!

Please let me know if it still stands, will have to get admin Greg involved.

Hi.

Go to https://escatter11.fullerton.edu/nfs/prefs.php?subset=global and on the memory section set all to 95%.

State-of-the-art factorizations

Siever to use is: lasieve5f (16e credit, 16e Lattice Sieve V5 ),130 credits per wu.

Long time goals: "Gang of 31", now "Gang of 21".

The Cunningham project may be the longest ongoing computational project in history. See https://homes.cerias.purdue.edu/~ssw/cun/. As of this update (9th January 2025) there are 21 numbers as yet unfactored from the 1987 published version of the book. These are all numbers of the form 2^n+1 for n < 1200 and 2^(2n+1) +/- 2^(n+1) + 1 for n < 600.

During the last number of years, big push has and is being made to finish all Mersenne numbers (2^n-1) for n < 1200, but more power is needed.

It would be nice to finish this last small set of composites (21 now). They were added to the tables in the early 1960's by John Selfridge and D.H. Lehmer, so have been waiting for over 60 years to get done. Attempts to factor these numbers have been made since the time of Fermat, so they have strong historical interest.

Below is currently the work load table being run that uses the Number Field Sieve to factor these numbers with support from Yoyo on the ECM front.

This project pushes the state of the art in factoring algorithms and every little help is appreciated to finish these last 21 composites.
