Invitation to all teams and crunchers! This is a challenge and a Call to Arms for the NFS@Home BOINC project challenge!
We are asking you and your team mates to spread the word about this challenge.
The goal of NFS@Home is to factor large numbers using the Number Field Sieve algorithm and it is interested in the continued development of open source, publicly available tools for large integer factorization. Over the past couple of years, the capability of open source tools, in particular the lattice sieve of the GGNFS suite and the program msieve, have dramatically improved. NFS@Home BOINC project makes it easy for the public to participate in state-of-the-art factorizations.
Concerning target size of the factorizations there are four sievers applications available:
lasieved - app for RSALS subproject, uses less than 0.5 GB memory per thread
lasievee - work nearly always available, uses up to 0.5 GB memory per thread
lasievef - used for huge factorizations, uses up to 1 GB memory per thread
lasieve5f - used for huge factorizations, uses up to 1 GB memory per thread
How's the credit distributed per target wu?
lasieved – 36
lasievee - 44
lasievef - 130
lasieve5f - 130
Why the difference in credits?
The more valuable calculation gets more credit. Especially for 16e (lasievef+lasieve5f), the extra credit also awards for the large memory usage.
What project uses what application?
lasieved - Oddperfect, n^n+(n+1)^(n+1), Fibonacci, Lucas, Cunningham, Cullen and Woodall for SNFS difficulty below 250.
lasievee - Cunningham, Oddperfect, Fibonacci, Lucas or other for SNFS difficulty above 250 to ~280.
lasievef - push the state of art for very difficulty factorizations, above SNFS difficulty of 280
lasieve5f - push the state of art for very difficulty factorizations, above SNFS difficulty of 280
Does the project have badges?
Yes, You can have up to 5 badges:
Top 1%, 5%, 25% recent average credit
Total NFS credit since beginning of the project
14e credit since app credits were implemented on January 3, 2014
15e credit since app credits were implemented
16e credit since app credits were implemented
The levels for the credit badges are as follows:
10k bronze
100k silver
500k gold
1M amethyst
5M turquoise
10M sapphire
50M ruby
100M emerald
500M diamond
