Dear crunchers

I know that what I suggest is a very long challenge. I suggest it to be either on the ESP, PSP or SR5.

If I´m correct our honary cruncher - Lennart - was born 65 years ago on august 3rd 2019. Most projects on Primegrid wouldn´t really have been anything of what they are today and might not have been on Primegrid at all if it weren´t for Lennart. So to honour Lennart and celebrate his birthday and the great work he has done for Primegrid and the influence he has had on Primegrid, I suggest a 65 days challenge in Lennarts honour :)

I know it is a long challenge, but it is still not comparing to the time and effort Lennart did to doublecheck and prepare Primegrids great projects. Why 65 days you may wonder, well one day for each year since Lennarts birth :)

My personal suggestion will be to run ESP, because doing a 65 days challenge on SR5 might mean that we have to start preparing more SR5 work in the near future - while ESP has a lot of work remaining and all the work is fully sieved. ESP was also started by Lennart, so we honour Lennart by giving one of his pet projects a really big push - a push where 1 or 2 primes might be found :)

As mentioned a 65 days challenge is long time, but a long challenge in order to honour one of our most productive projectsupporters is no doubt in its place and well it wont be 65 years since Lennart was born again so we will propably not have such a long challenge in the near future :)

So let me hear what people think, any pros any cons in regards to such a long honary challenge?

My suggestion is to run from Saturday August 3rd 2019 to Monday 7th October 2019.

Final note, I really don´t know wether Lennart is dead or alive, if he is healthy or sick - I simply just did some research to see if I could find out more about Lennart and all I have is a likely (unconfirmed) birthday and age, so no need to ask me or any admins if more is known about Lennart :)

Looking forward to be hearing your feelings and suggestions.

Have a nice warm day and stay happy and healthy :)

You are most definitely wrong on that one :P


Anyways, I don't really like it. Long challenges get kinda boring after a while, you just end upp not caring and moving on, at least for me. It already happens with 2 weeks challenges, let alone with 2 month ones. Additionally, it's only two days away, we'd need to have this planned for much longer if we're to do this.

Maybe you should read that part again, it is actually 1 year and 2 days from now ;) ... much longer, yes that´s why I ask already ;) ... But thanks for your oppinion :)

All good ideas with me, I like Jim's idea ;). I also don't mind committing to an unusually long challenge - it is itself a challenge to remain so focussed for so long! Humans are capable of so much & there is a lot of inspiration in playing a long-game of sorts. Fine whichever project we go for - by that time all mine should be turq anyway, so personally I'd do 2.5~3M. Also a precise stop-time on the second is exactly the same as any other project so it doesn't matter if it is non-integer days.

The smallest prime attributed to Lennart there, is about 10^6024. The smallest physical meaningful interval of time might be the Planck time. If we do a challenge for 10^6024 Planck time units, that will be 10^5981 seconds, or 10^5973 years, or 10^5963 times the current age of the universe. People will need time to prepare for such a challenge, so I suggest we start on Saturday, 3 August 2954, at noon. /JeppeSN

This is all speaking unofficially: Playing with numbers, if KEP is correct Lennart would be 23741 days old on 3 Aug 2019. A challenge that lasted one minute for every day Lennart lived would be 16.4868 days or 16 days 11 hours 41 minutes. This year's SoB challenge was 15 days, so that's a number we could all live with.

Edit: I found an old chat log where it seems I knew that Lennart was born in August of 1954, so that agrees with KEP.

If you're willing to use something like a micro-VAX or a PDP-11, you could go back a bit further on the calendar.

Well since we are just throwing things out here, how about this one. We already have a lot of challenges. In some folks eyes the challenges take time away from what pet projects they enjoy participating in, along with some team things going on. So why not just dedicate the total primegrid output for X number of days in honor of Lennart. There will still be a dedication to the gentleman, and it will all be in honor of his love of everything supporting finding primes. Because at the end of the day here that's what this is all about. The first year just starts a baseline. The second year and so on, is to try to beat the previous year's output in primes, factors, points, etc. Everyone gets to crunch what they want and the project still benefits.

Sounds good to me - it's a one-off like you say & it will be an interesting feeling to PG overall to have this massive challenge going on for all that time. How about someone set up a vote?

Did we end up with a conclusion on the various suggestions in this thread? :)

Happy late summer everyone

KEP :)

What about ppse? Lennart found the vast majority of his primes in this project.

How about a 65 HOUR challenge? And, make it a combo CPU AND GPU, and allow bunkering.... Best of all worlds - short time frame that gets a lot of crunching done!

I think 13 days is best length. Cause it's the largest factor of 65.
