PrimeGrid's 2019 Challenge Series Hans Ivar Riesel's 90th Birthday 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 ;-)

PrimeGrid's 2019 Challenge Series Hans Ivar Riesel's 90th Birthday Challenge

Post by UBT - Mikee »

Hi

Totally forgot to mention this last week - it's been running for a few days all ready but still 2 days to go

http://www.primegrid.com/

Team is currently 46th out of 102 - 39 WUs done

We got...

Rimmer161 with 18
Meddy2065 with 15
and me with 6

I'm running 4 threads per WU and they're taking about 15 hours each. Credit for the challenge is issued when reported, standard credit when the wingman reports in.

Mike

Just realised we got at least 2 Rimmers in the team! Well smoke me a kipper!

Hi Mikee,

I'm pretty limited at the moment but I've added a host to it.

Hi Mike

Thanks for the heads-up !!

I'll add some CPUs and GPUs to the effort. :-)

The stats and league table are here:

Hi TIm,

It's CPU only.

Hi Mikee,

What on earth are you running them on? I've just finished my first one (four cores of an i7 4790) and it only took four hours! :o
(Second one is looking like 6 hours)

Hi Mark

oops - didn't read the Challenge info on the website, so thanks for the tip :-)

For others, who don't check such details, the Challenge only involves the TRP-LLR tasks, which are for CPU only - no other tasks are involved on this Challenge...so, I've had to abort a few 321 Sieve tasks, but the GPU tasks will carry on, as I need to boost my PG credits a wee bit.... ;-)

Hi Mark

Looks like Mikee has this:
AuthenticAMD AMD Ryzen 7 1700 Eight-Core Processor [Family 23 Model 1 Stepping 1] (16 processors)
and with CPU times of between 57,000 and 110,000 seconds per task !!

Hi TIm,

Ah, that'll be the Ryzen lack of AVX performance then.

I've completed two so far, one @ 24,440 seconds and the other @ 14,071 seconds.

Hi Mark

I think I'll be lucky to complete ANY before the Challenge ends.

My Xeon shows a "Remaining time" of anywhere between 1d 10hrs and 1d 23hr... for each task currently running :-(

And that's with it being clocked at 2.9 GHz...about 10% higher than "standard".

I guess that this set of tasks are really just about clockspeed...and AVX of course ;-)

Hi Tim,

You do have them running multithreaded don't you?

First post here http://www.primegrid.com/forum_thread.php?id=8556

Code: Select all

<app_config>
   <app>
      <name>llrTRP</name>
      <fraction_done_exact/>
   </app>
   <app_version>
       <app_name>llrTRP</app_name>
       <cmdline>-t 4</cmdline>
       <avg_ncpus>4</avg_ncpus>
   </app_version>
</app_config>
For four threads per task.

HI Mark

I just got home from work and my home PC (a quad core) is indeed running one task with 4 CPUs.

But the office PC wasn't - it was running one task per CPU core...14 in total leaving 2 spare for GPU and "normal office duties".

I've just remotely uploaded to the office PC, a suitable app_config file, to utilise 14 CPUs on each task, so the total time per task should reduce a fair bit. :ugeek: (I hope). (One needs to "Read config files" AND to shut down BOINC Manager and restart it for the app_config to work).


My app_config:

Code: Select all

<app_config>

<app>
<name>llrTRP</name>
<fraction_done_exact/>
<max_concurrent>1</max_concurrent>
</app>

<app_version>
<app_name>llrTRP</app_name>
<cmdline>-t 14</cmdline>
<avg_ncpus>14</avg_ncpus>
</app_version>

</app_config>
So, thanks again for another tip ;-)

I blame Mikee for not giving everyone the full SP on this...;-) !!

That's what I expected, my initial predicted times were well over a day each running on a single core. Using four cores now and they're a matter of hours.

That should speed things up a bit :lol:

I only needed to read the config files again? But then, I do run quite old versions of Boinc, it may have changed in the past couple of years :D

I agree, what with him being team leader as well!
