Srinivasa Ramanujan Challenge - 3-10 November
Announced is a challenge at FPS (factorial prime search) from 3rd until 10th of November. I suggest we start at 12:00 UTC and end at 12:00 UTC.
Srinivasa Ramanujan was an Indian mathematician and autodidact. Though he had almost no formal training in pure mathematics, he made extraordinary contributions to mathematical analysis, number theory, infinite series, and continued fractions. Department of Mathematics in Jaunpur India is running a one week Workshop from 3rd till 7th of November. More details at http://rsmams.org/newsdetails.php?id=17
More about factorial prime search can be found here. News and infos about the PRPNet client can be found here.
To take part, you have to activate the following lines in prpclient.ini:
server=FPS:100:1:prpnet.primegrid.com:12002
Remember you also need to run the "install", "update" and "start" batch file for the appropriate number of cores on your PC. Give it a go before the challenge to iron out any problems.
Stats will be available at the well known place here.
All previous PRPNet challenge stats can be found here.
Good luck!

My ISP will reboot my server in the next few days, because of a security fix. Unfortunately the exact date was not mentioned.
This should not affect the challenge, except they will reboot exactly tomorrow at challenge start (12:00 UTC). I will do some backup-copies at my crunchers to prevent this unlikely event.

This quarter of an hour (12:15 UT) may be the only time I will ever be in the lead in a PrimeGrid challenge. /JeppeSN | |

In mathematics, a Ramanujan prime is a prime number that satisfies a result proven by Srinivasa Ramanujan relating to the prime-counting function:
http://planetmath.org/ramanujanprime
The first few are 2, 11, 17, 29, 41, 47, 59, 67, 71, 97, 101, 107, 127, ...
Moving over to FPS for the Challenge. Will evoking Ramanujan yield a prime? Only one way to find out. | |

Collectively we've done 2,364 WUs, had 32 competitors from 15 Teams and advanced the leading edge past 220,922 on both the plus and minus sides. No Prime was found, but we're that much closer I am sure.
Remember to make a suggestion at the 2016 PRPNet Challenges - Discussion and Dates thread for the December challenge.
Well done to everyone who participated. See you at the next challenge!

Oh oh, I'm out of the top five. I scored on 100 numbers during the challenge (7th place).
It could have been at least 204 (2nd place), if... I had bunkered for 9 days
and started on time
and used optimal number of instances for my system
and not run 2 to 6 PrimeGrid tasks most of the time
and stopped a couple of other processes enumerating Egyption fractions for the last 3 weeks
and closed 4 LibreOffice spreasheets, 2 PDFs, 27 browser windows/tabs... At least I segregated most of that stuff onto a couple of cores. One of these days I need to learn how to set up cgroups in Linux; doh! more browser tabs. ADHD? No, just never enough time to do everything... plus life. ... ... ... Just thinking about that early retirement lifestyle scenario now.
Is PrimeGrid/PRPNet an attraction, or a distraction. Now there's a topic for general discussion. Sorry, I'm too busy to participate. | |
