1) Message boards : News : AVX-512 Now Supported by LLR (Message 129682)
Posted 8 hours ago by Profile Michael GoetzProject donor
All of PrimeGrid's LLR applications now support AVX-512 on CPUs with that capability. Those of you that have been using app_info.xml/anonymous platform to run LLR 3.8.23 may now use the stock app if you wish, which is also LLR 3.8.23.

Because we are getting close to the next challenge and I don't think I will have time to try it before then, I need to ask a really stupid question: Do I need to do anything to get AVX512 working on my X CPU? I am hoping all I need to do is download the workunits and it will just work?


It's completely automatic.

The next LLR task you get will run AVX-512 if your CPU supports it. Note that tasks downloaded BEFORE the new LLR was installed will NOT be able to use AVX-512. V8.02 tasks do not support AVX-512. 8.03 tasks do.

I am running ESP right now and it is slow on the X CPU compared to the 9900K - approx 2 days (yet to finish) versus 30.5 hours.


All of your ESP tasks are older v8.02 tasks, which your computer downloaded before the new LLR was available.

The 32 bit Linux app is also live.

The 32 bit Windows app is waiting for some tests to finish.

ANNOUNCEMENT

The 64 bit AVX-512 LLR apps are live. You do not need to use app_info any longer to run the 64 bit apps.

We're still doing more testing on the 32 bit apps.

Even though the 64 bit apps are released, please continue any tests you've reserved.

Posted 1 day ago by Profile Michael GoetzProject donor
What is the difference between GCW and WOO (both are Woodall Prime searches ) as far as the "#" badges go? Seems like WOO takes way longer. ..?


Woodall can only earn an "M" badge. GCW can earn the "#" and "M" badges.

The "#" badges are awarded for finding the first prime in any GCW base. GCW searches for Generalized Cullen and Woodall primes, meaning in a base > 2. Woodall only searches base 2, and there's plenty of known "not-generalized" base 2 Woodall primes.

Will the last unfinished WUs be finished manually? The finish date depends on it.


Probably.

There's 2 different finish dates: When the last DC tasks are initially sent out, and we start working once again on real leading edge candidates, and when (probably 3 to 6 months later) the wingmen finally finish working on the DC tasks.

We are down to 5083 candidates that have not yet been turned into tasks, out of a total of 149364 candidates that needed to be checked. We're burning through about 100 each day, give or take.
8) Message boards : AP26 - AP27 Search : AP 27 Search (Message 129658)

Hi, I joined PG about 1 month ago, (April 2019), and have found about 150 AP. As the list grows it's more difficult to identify the individual records. As a member of CSF, I report each find with a screenshot record. Any chance of a mre friendly search sequence in the list. Thanks.


The lower limit on what the system shows you is rather arbitrary. For every AP20 you find, there's about 4 AP19's the system doesn't bother showing you. And about 16 AP18's, and so on.

If the number of AP20's you're seeing is too many to be manageable, ignore them and only be concerned with the AP21's, or even the AP22's.

Regardless of what you choose to see, using the notifications for reporting the results elsewhere is a good idea.

At this time, I don't plan on making any changes to the AP27 reporting, although it can't hurt to give me suggestions for how you might like to see it work.

We've found another n=15 (32768) prime!

On 19 May 2019 20:17:31, the 265,340 digit prime 125178918^32768+1 was found by candido using the OCL2 (combined) app.

The double checker of this task was ILW8 on 19 May 2019 20:18:01 using the OCL2 (combined) app.

Congratulations!
10) Message boards : News : Reason you should upgrade BOINC (Message 129645)
Posted 1 day ago by Profile Michael GoetzProject donor
I have allowed BOINC to use 3 cpus and 1 NVIDIA GPU.

Normally 2 cpus run 2 PPS (LLR) tasks and the gpu runs another task often from another project. So I have 3 tasks running quite happily.

However, when the gpu is used by a Genefer 21 task, BOINC only allows 1 other cpu task to run (a PPS (LLR) task).

It seems that BOINC believes that the Genefer task requires 2 cpus although it is supposed to only use 0.0763 of a cpu. I can see that only 2 cpus worth of 6 cpus is actually being used.

What's going on.


Boinc 7.14.2
W10 prof with latest updates.
Genefer 21 3.21
PPS (LLR) 8.02


That's a weird one. I suspect it has something to do with your BOINC settings, but that's not something we can see on this end.

If you want help diagnosing this problem, please start a new thread in the Number Crunching forum. This thread is about extremely old versions of BOINC not being able to support useful features.
