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

Might not be enough, I've woken my Xeons up
Not sure what was wrong with them, no tasks running and soon as I did a manual refresh they downloaded work and started crunching

Hi Mark
Excellent stuff...glad you got them working...
If it was your "old" Xeons (E5-2670's types) that had no work, then you may have had the same issue that I had as 2 of my 3 PCs use that CPU. However, my workhorse PC (using an older Quad core) also had the problem, so it may not be "Xeon-related" but some other factor?
In my case, I *KNOW* I changed and saved my PG preferences to allow the 321-Sieve tasks, but my PCs didn't recognise this change...and only by going back to the Preferences and switching them around and then back again, did it eventually result in tasks downloading. Maybe the PG server cache wasn't updating with the amended preferences, possibly due to lots of people making updates due to this Challenge?
Well, we're into #12th so far out of 108 registered. With Mark's monsoon 'tailwind' coming in, we've managed a 'League 1' global position at least, despite several mishaps of various descriptions ...

I've got 165 tasks in my "pending" section on the PG website...I doubt if all of those would be validated before midnight...esp as the quorum for these tasks is "2"...so, until a wingman completes and validates a task, then we're sort of "in limbo" on the credits side.
Perhaps they should have reduced the quorum to "1" but as we're all in the same boat, it's just chance as to who gets credits before the deadline.
Here are the stats direct from the PG website:
Challenge: International Education Day
App: 12 (321-Sieve)
(As of 2020-01-24 18:28:22 UTC)
328030 tasks have been sent out. [CPU/GPU/anonymous_platform: 328030 (100%) / 0 (0%) / 0 (0%)]
Of those tasks that have been sent out:
2171 (1%) were aborted. [2171 (1%) / 0 (0%) / 0 (0%)]
694 (0%) came back with some kind of an error. [694 (0%) / 0 (0%) / 0 (0%)]
225407 (69%) have returned a successful result. [225413 (69%) / 0 (0%) / 0 (0%)]
99787 (30%) are still in progress. [99787 (30%) / 0 (0%) / 0 (0%)]
Of the tasks that have been returned successfully:
don't worry, you've been around longer than me and know that we've been invited to a bespoke crunch. Nothing too serious, a 1-day thing, and we've been doing whatever works. Glad you checked in. Homefarm,(Richard) is putting us to shame on CPU anyway, and he's more of a GPU cruncher!!!
The sprint series gets more serious later in the FB sprints, but would want Tim to confirm what we should do thereabouts. I just like crunching, and ideally for a good cause
When the challenge completes, we would prefer users "moving on" to finish those tasks they have downloaded, if not then please ABORT the WU's (and then UPDATE the PrimeGrid project) instead of DETACHING, RESETTING, or PAUSING.
ABORTING WU's allows them to be recycled immediately; thus a much faster "clean up" to the end of a Challenge. DETACHING, RESETTING, and PAUSING WU's causes them to remain in limbo until they EXPIRE. Therefore, we must wait until WU's expire to send them out to be completed.
Likewise, if you're shutting down the computer for an extended period of time, or deleting the VM (Virtual Machine), please ABORT all remaining tasks first. Also, be aware that merely shutting off a cloud server doesn't stop the billing. You have to destroy/delete the server if you don't want to continue to be charged for it.

I'll finish the ones I already have but I've switched to no new work from now. They wouldn't finish in time.
Hi Mark
I switched PG to "no new work" about 10pm, as I had just enough tasks to get me to midnight - and I then re-allowed T.Brada tasks, which are set on resource=0, so BM just downloads tasks as it needs them.
I was going to do a final PG Challenge stats summary, but I'll leave it to mid-Saturday morning.

Well, I’m pretty used to looking at your tailpipe, so get moving!!!!!
Richard - I’m mainly running Threadripper gear. Only a little bit of intel these days. I’m as shocked as anyone ... ha! Who would have thought ...
Great stuff, loads of cores and fast too. Pity TRs don't have AVX capabilities to match Intel extremes. If they did they would the Bee's Knees. Congratulations on the score!
Do they not? I’ve not really looked closely at AVX but, yes, lots of cores. I don’t have a ton of space so need to keep a high number of cores per machine. They seem to work very well, and keep on getting better ... as of 7th Feb they offer a 64 core!!
Anyway, good run all. Definitely not our smoothest effort, but a good bit of fun and a respectable result.
I’m back on TN-Grid and then will probably do the WCG run to map cancer markers 1st - 7th Feb. I think Chris C (Richard - Chris C is ‘ncoded’ on BOINC) is crunching WCG too, so that will help.

(610 BOINCers crunched 321-Sieve tasks over the 24 hour period - so a Top 50 position for 3 UBT members is pretty good. )
Well done to all who took part...and here's to the next Challenge.
