Primegrid Challange series 16-21 June

[kashi]

Little reminder for anyone who wishes to participate in the PrimeGrid Full Moon Challenge. This one is only a 24 hour Challenge so will be over before you can say Jack Robinson.  ;D

It starts at 25 July 18:00 UTC which is 4 am Monday morning Sydney time, so I will be running PrimeGrid from late Sunday night. If you wish to take part you need to select only Proth Prime Search (LLR) in your PrimeGrid preferences. It is marked as Full Moon Challenge.

Only this subproject is counted in the Challenge.

Only WUs downloaded after the challenge start time will be included, so before I go to bed I will be using the recommended procedure of suspending all other CPU projects and setting both "every" and "Additional work buffer" to 0.00 then clicking OK in BOINC Manager>Advanced>Preferencesb>network usage tab. When I get up on Monday I will increase the cache a little.

Good luck to all Full Moon Challenge crunchers, aarooo!

I have primegrid set to only give the Proth Prime Search (LLR) so I am ready.  I will just stop the other projects for a day, I think I will need to do that before I go to bed tomorrow night.

[kashi]

I'm ready too with BOINC Manager already attached to PrimeGrid and Proth Prime Search (LLR) selected in project preferences. Just have to remember to change over to PrimeGrid after the German Grand Prix.

Stats will be available on the PrimeGrid home page next to the clock within 30 minutes after the start. 

BOINCstats provides hourly updates of Project Challenges. There you can view user and team credit and ranking trends.

[kashi]

I was 91st or something in the first half hourly update but am now 202nd.  The team is 32nd, not bad considering work fetch issues. 

Work fetch has been sporadic since the start, I think the work units of this type are too short for a Challenge, the servers can't cope.

Aha thought I was going to run out but just got 91 tasks which tops me up to 168, that will keep me going for about 3 hours.

Server congestion due to short WUs meant the challenge was compromised for many but 27th was still a good team effort. Well done everyone.      

The next Dog Days of Summer Challenge has WUs that take about 3 hours on my computer so that should work much better. Higher BOINC credit too on 64-bit, just over 8K per day on 6 cores of my W3520 @ default clock.  ;D

[Dingo]

Well done those who took part 

Wonder if we would get a better response for the next one if we put out a team email to the members?

Dennis.

I try and keep the emails to a minimum but I will add the Primegrid Challanges to the next team email for the next AA.

Started 5 minutes ago.

I've started a bit late, but I'm in to.  Wu's seems stable on my machine.

[kashi]

Yeh I almost missed the start too. I thought it started tomorrow morning at 4am, not this morning. Only noticed by accident when visiting the PrimeGrid site to check on a long pending Seventeen or Bust task.

I like these short challenges, just a quick little sprint on one project and then back to your current project of choice.

No shortage of work or server trouble like last time. Stable as a rock on my computer and granting about 65 cr/hr.   

[kashi]

Well done to all 11 Dog Days of Summer entrants.         

Once again team member redback earned Challenge points by finishing in the top 100 and the team finished in 26th position.

That's strange you didn't show in the results, they usually don't make errors.

Are you sure you downloaded the tasks you completed successfully after 18.00 UTC on 20 August (4am on 21 August Sydney time)? Only tasks downloaded after the challenge start time count towards the challenge score.

The next one is the most challenging of all because the Prime Sierpinski Problem (LLR) tasks will take 2-3 days to complete on my computer.
