Help test 2995125705 - Find a new top 5000 prime!

SlashDude · 2004-03-05, 16:42

It's now time to help find some primes for another 15k!

We would like to gather more information on this 15k, so we would like to continue testing it to n=1,000,000. We now have llr .txt test files ready to go to help search for k=2995125705 primes! (This part of our project is the same idea as 321 search)

How to help search for primes:
1. If you don't have LLR.exe, download llr.zip here!

2. Download one of the available test files below (Right-click link, and select "Save Target As") Save the file in the same folder as LLR.exe FYI- The files in the 290,000 to 300,000 range take about 3 days to complete on a 2.2GHz P4. Post to this thread that you have downloaded a test range.

3. Open LLR, and select the "Test" menu, then "Input Data"
In the "Input File (From NewPGEN):" box enter the file from step 2 (IE - 300to305.txt)
In the "Output file:" box, enter prime.txt
Click "OK"
(If the LLR icon doesn't turn from "Red" to "Green" repeat step 3, and it will start the 2nd time you hit "OK")

3.5 If you see a number show up in the prime.txt file, you have found a new prime that will qualify for the top 5000 prime list! If you don't have a 15k top 5000 prime list prover code, I'll help you set one up so you will receive credit for the new prime!

4. When the test is complete, please mail the lresults.txt file renamed (see below) and zipped to Kosmaj, or post the renamed txt file to this thread.
Renaming convention: if you worked on the 300to305.txt file then please rename lresults.txt into lresults300to305.txt.

If you have any questions e-mail me and I'll try to answer your question.
