Hi Chooka03

I was thinking the same last night, threw a few cores and the gpu on to it for a test run.

This project really heats up the computer lol.

Good luck

I wish they had given us more of a heads up though. I only saw this message this morning. Guess I'll have to dump a lot of Rosetta work to begin.
I'm only going to use CPU task though. PPSE (LLR), & LLR (MEGA)

Actually.... when they refer to MEGA Primes, do they mean running Proth Mega Prime Search LLR (MEGA) or Generalized Fermat Prime Search n=17 Mega (GFN-17-Mega)

Edit - Maybe I'll do GPU tasks also...it's only for 1 month :)

Edit #2 - I re read the tips - • Only run GFN on a GPU. Use your CPU for LLR tasks where it will be much more efficient.

I started running Primegrid yeaterday afternoon abd am running CPU, (PPS,PPSE and MEGA) I am not using the app_config to make cpu apps run multi threaded, as detailed on the forum. http://www.primegrid.com/forum_thread.php?id=8409#125783 (http://www.primegrid.com/forum_thread.php?id=8409#125783)   I am running GFN 16,17 and 18 on my GPU as well.

Hey Dingo, when they say change the cache to "0", does that mean I have to set that for each PC running Primegrid? If so, is there a way to do this for all machines using BOINCTASKS?
Because I had it set to 0 today but found no CPU tasks were downloading, just GPU work? Once I set it to 1 day's work, the CPU tasks downloaded.

I'm not bothering with the app_config file either.

Gee.... Primegrid runs HOT doesn't it! I can feel the temperature rise in my study even with the air con going. 30.1 at my monitor I've also seen my T/R struggling once again and throttling back to 3.0Ghz :(

Yea those LLR work units run really hot,  on your threadripper i'd use no more than 16 threads at a time.
Title: Re: 2019 Tour de Primes
Post by: Dingo on February 01, 2019, 02:42:35 PM
Primegrid will test your machines as they run HOT HOT HOT.

BOINC Tasks you can change the "Boinc Preference" on one machine at a time not all at once and the priciple is the same as in Boinc Manager below.

The whole idea of the Challenge is to find Prime Numbers and to do this you must be the first to process the work unit and send it back.  That is why "Store at least X days of work" and "Store up to an additional X days of work" are set to "0".

The preference thing is a bit difficult.  If you have never set preferences in Boinc Manager at the machine level then you are using your Global preferences that was set on on some project in the past http://www.primegrid.com/prefs.php?subset=global (http://www.primegrid.com/prefs.php?subset=global) and you can change this and it will change all machines the next time they update or the BOINC client is stopped and re started, not BOINC Manager as stopping and starting the manager does nothing.  

However, If you have ever changed the preferences in Boinc Manager then you are using local preferences for that machine only.  You will need to one of the following on all the machines where you have a local preference.

When you open the "Computing Preferences" in Boinc Manager, look at the top it will say that you aree using Local or Global.
a.  If it says "Using Local preferences" then you can.

    1.  If you have set you Global preferences on Primegrid then click the button "Use web prefs" , or
    2.  If you want to keep all the local peference change the options in Boinc Manager.

b.  Same as a. but the reverse


a LOCAL preference over rules a GLOBAL.

I have a different preference on each machine because I want to change the CPU % etc locally.

Just a reminder of the following:

There's only 5 sub-projects that do not count:

* Sophie Germain (SGS) -- it's too small
* GFN-15 -- it's too small

* GCW-Sieve -- you can't find primes with a sieve task
* PPS-Sieve -- you can't find primes with a sieve task

* AP27 -- The primes found here are way too small

Everything else counts.

 :holy-moly I dropped the CPU usage to 25% on the T/R.....y CPU temp didn't change! 67/68 degrees!  :faint:
I think I'm going to have to give the case a good clean and reapply some thermal paste.

I've taken some of your advice Jugnut and slashed the CPU usage on my PC's. Can't be bothered with the others.

Hi All

Yeah I would have liked to had a go on this Tour De Primes, but too much heat in my study as well, would have cooked everything (Summer).

Its allright for those Northern Hemisphere crunchers with the Wild Winter they are having.

Good luck to those that are having a crack, may the prime be with you.

Cheers

That had crossed my mind too Tazzduke. It's stinking hot and now loud as hell with 6 PC's crunching prime. A whole month?? :faint:
I may follow your lead. It's 31.8 right now in mt study and thats with the rest of the house at 24 degrees.

A great time for the Northern hemisphere indeed.

Yup the more crunching power you have the more chance to find a prime.  I am still trying and have 238 tasks pending which means I was the first to return the task and if it is a Prime it is mine.

Has anyone seen Scott Brown's stats?  :faint:
Check out how many primes he's discovered. It's crazy!  :crazy

Oh and I believe he's a world record holder.

Title: Re: 2019 Tour de Primes
Post by: chooka03 on February 04, 2019, 05:55:49 PM
So how does this work guys?

http://www.primegrid.com/workunit.php?wuid=596203723

Scott Brown's i7-3770S completed this PPSE WU in 819 sec (well that' the run time anyway) and my Threadripper completed the wu in 2009 seconds. What am I missing here?
All my PPSE work units are taking 2000 seconds. Is that longer than usual?

Also.... if the wingman finished 1sr, do they get the credit if a prime is discovered? Meaning, if I have very few 1st validations, am I wasting my time?

Even an i5 8400 finished a PPSE WU in 635sec vs my 4930K which finished in 1800 seconds?
http://www.primegrid.com/workunit.php?wuid=596107468

I'm not really sure how this all works.
Title: Re: 2019 Tour de Primes
Post by: Dingo on February 04, 2019, 06:04:19 PM
He has put in the app_config to use multiple threads I think.  The run tine is 819 but the CPU time is 1323.5.

I have just started using the config file and am using this on my 16 thread Ryzon

Quote
<app_config>
  <app_version>
      <app_name>llrPPSE</app_name>
      <cmdline>-t 4</cmdline>
      <avg_ncpus>4</avg_ncpus>

      <cmdline>-t 1</cmdline>
      <avg_ncpus>1</avg_ncpus>
  </app_version>
  <app_version>
      <app_name>llrPPS</app_name>

      <app_name>llrMEGA</app_name>
      <cmdline>-t 5</cmdline>
      <avg_ncpus>5</avg_ncpus>
  </app_version>
</app_config>

EDIT:  the conffig only seems to be downloading PPSE work for some reason.
EDIT 2 I changed the config file so PPSE only used one core and the other tasks downloaded ??  Something to do with total of 11 ??
No answer for the i5 is seems very quick.

My machine was doing a PPSE between 1500 and 2000 seconds on a single thread.  Still waiting to see a new tasks run through on 4 threads.

Post by: chooka03 on February 04, 2019, 07:10:13 PM
Oh ok. Thanks Dingo  :thumbsup:
I just re read this bit.. " He (or she) who finds the prime FIRST is the discover of the prime. It's a competition between you and your wingman. While having a fast computer helps, your computer is only useful when it's running a task."

Hmmm... I think I might be wasting my time then. I have bugger all 1st validations.
Title: Re: 2019 Tour de Primes
Post by: Dingo on February 04, 2019, 07:17:47 PM
Your wingman on that first task does not have hperthreading tuned on so 1 core is one core not two threads.

EDIT:  Just looked at the second wingman and he also is running 6 cores no Hyperthreeading. 

CPU type   GenuineIntel
Intel(R) Core(TM) i7-3770S CPU @ 3.10GHz [Family 6 Model 58 Stepping 9]
Number of processors   8
Coprocessors   ---

My computer has hyperthreading on which I might turn off later:

CPU type   AuthenticAMD
AMD Ryzen 7 1800X Eight-Core Processor [Family 23 Model 1 Stepping 1]
Number of processors   16


@Chooka You have a lot of tasks "Pending" which means you were the first to return the task.
Title: Re: 2019 Tour de Primes
Post by: chooka03 on February 04, 2019, 07:47:22 PM
Oh ok.

Gee...well I tried that app_config file and I see it just runs 1 WU at a time. Is that right?
I have my BOINC settings to "use 50% of CPU"

I notice it now says (16 CPU's) because I set mine to "16" as that's the number of cores I have. I thought it would run 16 WU's consecutively? Mind you... My T/R is now running at 70% load but back to full speed! yay  :crazy

Hope this works - (http://i65.tinypic.com/33nf0qu.jpg)
Title: Re: 2019 Tour de Primes
Post by: Dingo on February 04, 2019, 07:55:50 PM
It runs what ever you state as long as you have enough cores or threads.   You set yours to 16 so it will run one task on 16 cores.  if you set it to 5 it would run 3 tasks five each but you would not use the 16th core unless you had a application set to 1.

I would abort all the ones "Waiting to Start" if you are going to leave it at 16 so you can return work quicker.  

I edited the post I put up before as I found that your second wingman does not have hyperthreading on either so is using true cores not threads.

Which one is set to 50%, it must be % "CPU Time" which will just use 50% of the CPU processing power  ??  Unless you have 32 threads and you set "% of the processors" to 50% which is 16 threads ??
Title: Re: 2019 Tour de Primes
Post by: chooka03 on February 04, 2019, 08:13:45 PM
Ahhhh ok.
No I have it set to 50% of the CPU's.

So I tried setting it to 5 and you are right. I now have 3 WU's running. I'm not worried about the spare core. The GPU can have it lol. So would 3 tasks running at the same time be best? And I gather that I leave the CPU usage to 50%?

I just tried setting it to 100% but I think that's going to be too much?

Edit - Wow... If I just ran 1 WU across 16 cores, WU's complete in about 10min instead of 30min. I'll wait and see what 3 WU's does across 16 cores.
Title: Re: 2019 Tour de Primes
Post by: chooka03 on February 05, 2019, 07:07:28 PM
Nope...just can't get my head around these app configs  :compbash:
Trying to set it up for my 6 core and I don't know if I should have BOINC set to 50% or 92%. Then in the app config, if I set it to >1<, 6WU's run. If i set it to >2< & 92% usage, then 5 WU's run.
If I set it to >2< and 50% CPU usage, then 3 WU's run :(

I get so frustrated when app configs are involved :thumbdown:
Title: Re: 2019 Tour de Primes
Post by: chooka03 on February 05, 2019, 08:10:50 PM
Ok ok .... I managed to find a few minutes for testing. This is what I came up with.

i7 4930K 6C/12T

1) App config setting - >2<. @ 50% CPU usage set in BOINC = 640 seconds. That has 3 WU's running consecutively not including the GPU WU. 640/3 = 213.3 seconds/WU.
2) App config setting - >2<. @ 92% CPU usage set in BOINC = 980 seconds. That has 5 WU's running consecutively not including the GPU WU. 980/5 = 196.0 seconds/WU.
3) App config setting - >6<. @ 50% CPU usage set in BOINC = 314 seconds. That has 1 WU's running consecutively not including the GPU WU. 314/1 = 314.0 seconds/WU. (Funny enough, changing BOINC from 50% to 92% made no difference what so ever.)
4) App config setting - >1<. @ 50% CPU usage set in BOINC = 1260 seconds. That has 6 WU's running consecutively not including the GPU WU. 1800/6 = 210.0 seconds/WU. (I think this would hurt my GPU crunching as it appears starved of a core)

Firstly...have I done the above correctly?
Secondly, it would appear that running >2< @ 92% is the best option? Or is it the first method at 50% CPU because it finishes in 640 seconds?

Did I get that right?
:fingers

You add the complexity with changing the % usage.  I have 16 threads and I am running at 93.75% so I am using 15 cores for CPU work and .203% on my GPU.  I have set my app_config to 5 and have 3 tasks running each using 5 threads.  I am only crunching PPS and MEGA tasks and because all the tasks are not the same they are running between 1700 and 4000 seconds for MEGA and between 1090 aand 5000 for PPS.  I only change my % when the computer runs slow and with Primegrid I can max it out.
http://www.primegrid.com/results.php?hostid=914558 (http://www.primegrid.com/results.php?hostid=914558)

Not sure if that helps  No matter what your times are a mile better than mine and it may be because of the % usage ???

Thanks Dingo.
I just decided on the running of >2< and 50% usage on my Hexacores. That'll do bugger it :)
I have noticed a HEAP more 1st's so I guess something is going right.

Edit - I just looked at your link Dingo. Your PPSE run times are what mine were like prior to using my current settings. Mine have come down to around 800 seconds.
It's a difficult pill to swallow only using a fraction of the cores available but the WU's are finishing much quicker.

Mt T/R is set to >5< and 60% usage, so I have 4 WU's crunching + the GPU. My speed is down to 3.4Ghz in task manager due to the heat but I can handle that.

Hi There,

Just checking out this guy, has 8 computers with a total of 484 Threads (242 cores), including 4 x AMD Ryzen Threadripper 2990WX 32-Core Processor

Yep does one of those Workunits on his RTX 2080ti in 85997 seconds for over 943,990.64 credits.

My god, must have one their version of the POWERBALL/LOTTO.

Myself, I would have dropped a couple of those RTXs and got more CPU cores lol. 

Also probably has access to cheap electricity (He could be well connected - wink wink) lol  :BigGrin

Thanks mate...I see you haven't got one yet, but keep trying and fingers crossed.

You have had 2 x double checks so far so getting close.   http://www.primegrid.com/challenge/tdp_2019_dc.php

In Boinc computing preferences under options, make sure u set cpu usage to 50% and store zero days of work and additional work.

This will cause your cpu tasks to finish quicker, and you only download what you are crunching, which gives you far better chance of being first.

I,ve had heaps of firsts, but took a long time to get one, so it is still luck basically, but the more gpu/cpu tasks you can complete, the more chances you have, so throw everything at it mate.

BTW you probably knew all this but thought I would say it just in case, and it may help someone else anyhow who reads it :thumbsup:

Congrats to others who have got one so far as well, and lets hope we all get another :wink

Hi Magpie.

I haven't seen that page before that you linked and I don't understand the 2 x double checks?
I saw my name in that list twice. What does that mean?

Thank you for the tips. I do indeed have 50% usage and I'm using that app_config mentioned on the forum with 0 days work.

What does this whole 1st thing mean? I see I have quite a few of them but don't really understand how it works. I'm sure luck has a bit to do with it too :)

ps - I won't hold my breath finding one. If this is anything like my gambling luck, I'm a shocker! lol

Yeh Mate what happens is a work unit gets sent to 2 x people to process, to ensure it is accurate by both computers getting a similar result.

If say my computer gets it finished and returned before your does, I will be awarded the 1st to return.

Then if it is also a prime number work unit, because I was first to return, I will get credited with finding it.

You on the other hand are just the double checker, hence that other list of unlucky people who basically found one, but did not get it returned first :cry

Don't worry, I have had quite a few double checks myself, and this shows why it is important to get them back asap.

Still technically you get about 1st, 50% or the time, so its still difficult to get a prime, especially if its sent to say someone with a 2080ti, and you have say a 780ti, they will beat you returning the gpu task if you get them similar time.

Same goes for cpu, depending what you have, and the way you have it set up.

People who hoard work units have a low chance of being first, and therefore don't usually get to be the prime finder, but only a double checker if one turns up.

Of course, timed out work units, or aborted ones can make a difference, and here the slower machine can beat the faster one, if they have completed, or nearly completed by the time the faster machine get the work, so really it all balances out in the long run.

That page I linked you to was set up just for the Tour, so see how many people actually are double checkers.  Notice how scott brown had 7 he found, and 7 double checks as well.  Only the 7 he found count towards the Tour for badges and points.

Hope this isn't too long winded :BigGrin

EDIT:- Of course all those 1st you have in the list of completed tasks, if any turn out to be prime, you will get the badge for the Tour, so every one is a possible chance :thumbsup:

Congrats mate  :thumbsup:

Thank you for explaining that Magpie.
I guess my AMD cards also aren't really suited to Primegrid either for the GPU WU's.

Hey Chooka have a look at this:-

http://www.primegrid.com/show_user.php?userid=1014486

Click on primes tab, beside discoveries, and it will show those 2 x work units we were talking about.

If you click AP shows what you have found, and what you double checked also :wink

Greetings All

Yeah, bloody lucky with those two discoveries, man wish it was the Lotto lol.

Weather has cooled down a little bit, so have 3 x PC's running, each doing one workunit using 4 cpus per workunit and 1 at a time, no cache, lots of cross fingers for luck lol.

Now it could be another year or two or three before I discover another one lol.

Cheers

Hi Magpie,

Sooo what about this second WU? It says I finished it 1st but I didn't find the prime number? How does that work?

http://www.primegrid.com/workunit.php?wuid=595848972

I've switched one of my GPU's over to the Feeling lucky task. Takes about 3 days to run on my Vega 56 which I think will be quite long compared to other GPU's. Guess we'll find out in the next couple of days. I'll then switch it back to GFN - 16.

Looks like I'm getting quite a few 1st's for PPSE work units but only 7 - 10 per page of 20 tasks completed with GFN. I guess that's the AMD cards vs NVIDIA which are better suited to Primegrid as I understand it.

Hi Chooka03

Have a look at the sent timestamp and the reported timestamp, unfortunately with that workunit you referenced, you ended up being the wingman.

Wow by a whole 4 seconds  :thumbdown:
Thx Tazzduke  :thumbsup:

Ahhh...this was also on Feb 2nd which was before I followed the instruction and set 0 days work to queue and before using the app_config file.
Bummer.

Can I get some advice please guys. I have my BOINC settings to store at least 0 days of work but for some reason, it keeps queuing up some WU's? Even with 3mins until the next WU finishes, there's another just sitting there waiting. Is that normal?
Have I missed a setting somewhere? or does it always download 1 WU ready for the completion of the next WU?

Thx in advance.

:oz:

Post by: tazzduke on February 11, 2019, 10:48:32 PM
Hi Chooka03

I am not sure, is this for the CPU or GPU tasks, do you have both cache settings set to zero???

Store at least 0 days of work
Store up to an additional 0 days of work.

This is my app_config.xml file as well

<app_config>
  <app>
   <name>llrPPSE</name>
   <fraction_done_exact/>
   <max_concurrent>1</max_concurrent>
   <report_results_immediately/>
  </app>
  <app_version>
   <app_name>llrPPSE</app_name>
   <cmdline>-t 4</cmdline>
   <avg_ncpus>4</avg_ncpus>
  </app_version>
</app_config>

Which is the same one on the forum for the Tour De Primes.

BOINC for me downloads the next workunit, when I have less than a minute to crunch on the current one.

Regards

The only thing I can say is that I have noticed that if I have my computer set to 100% on a 16 thread system and I have the app_config set to use 15 threads then BOINC Manager downloads another work unit, although it cannot be worked on.

In the same cenerio if I set the machine to 93.75% which is 15 cores then it only downloads a new task when it get to a minute or less to finish the task it is processing.

Not sure why but I guess it thinks there is thread not doing anything but the app_config only says to use 15 ???
Title: Re: 2019 Tour de Primes
Post by: JugNut on February 12, 2019, 03:08:48 AM
You could set a 0% share in the prime grid web preferences, that way you should be guaranteed to just have 1 WU at a time per core.  Then it will also be 1 WU at a time for GPU too.
Title: Re: 2019 Tour de Primes
Post by: chooka03 on February 12, 2019, 05:41:25 AM
Hmmm thanks guys. I am referring to the PPSE work units.
My config file looks like this and I have BOINC set to 50% CPU usage just as they suggested on the Primegrid website.

<app_config>
  <app>
     <name>llrPPSE</name>
     <fraction_done_exact/>
     <report_results_immediately/>
  </app>
  <app_version>
      <app_name>llrPPSE</app_name>
      <cmdline>-t 5</cmdline>
      <avg_ncpus>5</avg_ncpus>
  </app_version>
</app_config>

I have >5< which runs 3 WU's across 15 cores so you might be onto something there Dingo.
I've noticed my PPSE run times are about 800+ seconds which seems a bit slow.
Maybe I just need to stop worrying about it.

Thx for the advice guys  :thumbsup:

Post by: chooka03 on February 12, 2019, 07:34:17 PM
Thx guys.

I'm still trying to work out the best app_config to have. I don't think >16< and running 1 x WU is the best option. Sure it will finish fast but I'll have a lower throughput.
I've been using >5< to run 3 x wu's but now I might try >4< to run 4 wu's.

No idea which is the right one though lol. Seems like a trade off, throughput vs speed.

I am going away in the morning so my main Ryzen machine with the 1080Ti will be off for a week.  I am hoping to get at least one more Prime before the end of the month and I have four dedicated Linux servers running at 100% while I am away and I will run my old laptop when I get to where I am staying for the week.

Hi Chooka03

Is that the only entry in your app_config file or is it have all the other sub projects as well.

If it is the only subproject, well you are missing the <app_config> entry which should be at the top.

PS, I have an app_config file which has all the LLR cpu subprojects in it.
