Good Riddance 2020! PrimeGrid Challenge

This section is where you can post topics related to Challenges from other websites, such as Formula-BOINC, SETI-Germany and BOINCstats, as well as project challenges such as from WCG, PrimeGrid et al.

As a Team, we really want to engage as many team members with these challenges, as this gives us a great way of attracting more members to our Team...plus we get to show our strengths as a Team by (hopefully) doing well in each one.

PS: I have moved lots of topics into this section where they are relevant...as you can see, we've always been happy to take part in Challenges...and long may that continue ;-)

Good Riddance 2020! PrimeGrid Challenge

Post by UBT - Mikee » Thu Jan 14, 2021 5:24 pm

PrimeGrid's 2021 Challenge Series
Good Riddance 2020! Challenge
Jan 14 00:00:00 to Jan 18 23:59:59 (UTC)

Hi

Being as no ones mentioned it I thought I better had!

This started this morning and runs for 5 days.

Just Homefarm and I in it at the moment.

If you want in make sure you just have Fermat Divisor Search LLR (PPS-DIV) Good Riddance 2020! Challenge project - easy to find as it says "Focus project". CPU only. Don't forget to deselect any others.

There seems to be 2 versions, short (900 CPU seconds for me) for 24 credits and long (55000 CPU seconds for around 1550 credits.

Why CPU seconds? You can select how many cores per work unit - I'm current using 6 cores so it actually takes 10000 seconds to finish a WU but 60000 actual CPU time. Plain as mud?

Hiya,

Sorry, some complications at work distracted me here. I've paused WCG and pointed the machines at this challenge.

One of my large rigs is offline currently, but I'll still get into it.

Cheers.

Hi Mike

Yup - I'm in ;-)

Don't know what you are finding, but some tasks are really short ( taking maybe 15 mins each) and which seem to be the "Main task" and get 24 credits each and others takes ages (taking between 6 and 12 hours each) - these are the Proof tasks and earn about 1568 credit each....

And yet there doesn't seem to be different names of the tasks, they are called pretty much the same thing...just luck of the draw as to which one's you get handed.

I had a look to see how things are going on my machines. Not much movement on my points as yet; it looks like most of the tasks I have, have been running for over a day and are showing over a day more to go.

Good to see Richard smashing it up the top of the charts there.

I moved all my crunching to full cores only i.e. without hyperthreading / SMT. I hope that pushes a few extra tasks through ahead of the deadline.
