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?!

NFS@Home has a partnership with yoyo@Home (https://www.rechenkraft.net/yoyo/) where some of the integers are ECM'ed to its optimal before being fed onto the NFS@Home sievers. This happens when a factor is not found.

yoyo@Home progress, per project, can be follow up at the following address:

https://www.rechenkraft.net/yoyo/y_status_ecm.php

We would like to thank all yoyo@Home users too for their work, keep the factors coming!

Hi all,

Thank you so much for your CPU cycles donation, it is much appreciated.
Back in 2009 when the project initiated only three applications were available: lasieved (14e Lattice Sieve),
lasievee (15e Lattice Sieve) and
lasieve5f (16e Lattice Sieve V5). Nowadays we have 2 more, the ones mentioned as smaller numbers.

If for some reason you are not getting any more work, most likely due to the fact that some of the server queues are empty, try to select at least those two new applications under your NFS@Home Preferences, like this:
Run only the selected applications
"lasieved - very small numbers, uses less than 0.5 GB memory, work may be infrequently available: yes
lasievee_small - small numbers, uses up to 0.8 GB memory: yee
lasievee - medium numbers, uses up to 1 GB memory: yes
lasievef_small - large numbers, uses up to 1 GB memory: yes
lasieve5f - huge numbers, uses up to 1.25 GB memory: no"

By doing this it will definitely get your cores busy with Wu's fitting lower memory systems. Be aware that lasieve5f (16e V5) will require more than 1.2GB/thread.

You're not getting any work because the applications you set to run have the queue empty. I recommend Going to "Preferences for this project" and select to get "lasievef_small" tasks too.

DSJR9453,

Please stop posting nonsense and request for numbers to be sieved when I don't see you deploying any CPU into NFS@Home. You will own the right to complain when I see you helping out with some kWh.

From now on all your posts will be deleted and further on you will be blocked if you keep with your current attitude.

Kind regards.

15) Message boards : NFS Discussion : 3,667- is P74 * P202 Question (Message 2142)
Posted 24 Mar 2021 by Profile Gigacruncher [TSBTs Pirate]
Post:
Hi there.

You are confused but thank you for your questions.

The P stands for prime factor and the number stands for number of digits.

The P74 and P202 are unique and are two unknowns. For this case they are represented as below. If you see on the status page another P74 it is not the same as this one. Notation thing and to simplify the results page although you have the link to pastebin for the all post-processing phase.

Sat Mar 20 02:17:11 2021 p74 factor: 25359506465081394537400918368811516993503730623239065990152596258171619851
Sat Mar 20 02:17:11 2021 p202 factor: 1230272830905372645155936347582471802810001959890217331006615213107201195904714920966951311311387729777205064177180055078095657461958973281700356722080397000095160208423082302916300621936315289528078031

3,667- means (3^667 - 1)

If you have time read this thread: https://escatter11.fullerton.edu/nfs/forum_thread.php?id=549
Bear in mind we are only doing the "2. Sieving for Relations" stage on BOINC, the " 3. Combine Relations" is done on a cluster (we have a grant) and "1. Polynomial Selection" is done externally or by direct known polynomials.

More about the project here: https://homes.cerias.purdue.edu/~ssw/cun/
To be honest we need even more power than currently is deployed here but slowly we will progress on the Cunningham project...lol

Go here:

https://escatter11.fullerton.edu/nfs/prefs.php?subset=project

And set to:

lasieved - app for RSALS subproject, uses less than 0.5 GB memory: no
lasievee - work nearly always available, uses up to 0.5 GB memory: no
lasievef - used for huge factorizations, uses up to 1 GB memory: yes
lasieve5f - used for huge factorizations, uses up to 1 GB memory: yes

Or if you’re running under other account just request the admin of it to create different NFS profiles( default, home, school, etc) allocating the settings mentioned above to one of the profiles. Then on your machine set it to it.
