The admin of SiDock has stated that he has changed the deadlines for work units now to just 2 days. So, don't get over anxious on bunkers just yet. He plans on keeping these short for the duration of the Pentathlon which will make things a little more interesting for those that bunker a ton on the side as "extra" in case their other projects run out.

Ouch - those old X5650's are very power hungry. lol

Got SiDock setup in my client. Let it get a set of work units just to see how it will do. Looks like about 6:45 per WU on here. It ain't got nothing on what many of you have but with just having moved the shop it is about all I can toss at it for this and during the day when I am working I'll have to shut it down. Factory water cooled Precision T7910... At the below load it is kicking the radiator fans up a notch or two. :)

Since only two days are allowed I'll reset it in a couple of days to bunker some work.

Yes they certainly are, but I figured they will be ok for a couple of weeks. An extra 24threads for a good cause. Now to just figure out why the G34 box only wants to effectively use 16 of the 32 cores....

For those new to MIP work units, they are hard on the L3 cache of the CPU. General rule of thumb is that they want ~5MB per work unit before you see a loss of performance due to the CPU constantly waiting for L3 to free up. Most people run a mix of work so that they get better results but in a challenge where only MIP is desired, you are kinda hosed. So, if you are bunkering now, you can load up all MIP but once the SiDock start date hits, you may want another instance or a VM to mix some SiDock work into.

For Sidock, watch out for intermittent "no task" available as of 10:01pm PT. It will normally replenish within the next few hours. Probably ok for most rigs unless you have superfast, SMT disabled, highly overclock system.

See green "rts" - ready to send. Task availability mimic saw tooth pattern. Right now it is zero and new tasks will be generated in the next few hours, hopefully.

yeah, I start suspending individual units here in a couple hours as my feeble, noob bunkering attempt

I might have misunderstood what you're doing, but if you're suspending Sidock before the tasks finish, make sure you have 'Leave non-GPU tasks in memory while suspended' checkmarked in your BOINC preferences(I don't have BOINC in front of me but I think it's under the disk tab). If Sidock is suspended before it finishes without that checkmarked you lose all the task progress since it doesn't have checkpoints.

Good I think mine worked out. When it added all of them for the new cores, they were all 20+ hours out. I assumed I didn't need to do anything else.
Simply letting it run is just fine. Even if you somehow manage to complete some work prior to the event launch a portion of it will go into "pending" and then get validated later after the contest starts (and count towards contest points)

From that page you can click on an individual team to get a bunch of other charts that show takeover plotting and other good stuff.

City run PrimeGrid starts on May 8
Thanks for the heads up. I got the post updated to reflect it.

Everyone, keep in mind that PrimeGrid has both CPU and GPU tasks. Plan your strategy accordingly by only selecting the work unit types you want to run so that you can still help out elsewhere per your plans.

The "City Run" event has been announced
This will be Primegrid as the project and the dates are as follows:
Start: 08 May 2021 00:00 UTC
End: 13 May 2021 00:00 UTC

If you haven't already you will want to sign up for primegrid here: https://www.primegrid.com/
Then make sure to add yourself to the team: [H]ard|OCP
Edit your preferences as described below and then lastly you will add the primegrid project to your BOINC client.
Last but not least keep in mind that this will run your GPU a lot harder than gaming (100% load ) so you will want to keep an eye on temperatures. I typically set a power limit so that things don't' get too hot of around 60% power target. You can certainly feel free to go higher or lower as you desire and temperatures allow but I would monitor it for the first few tasks to see how hot it gets for you. My 3080 for example gets into mid 60c at 65% power target

There is no stipulation on which primegrid subproject you need to run here but its really only worthwhile to be running this on your GPU's. Also while this doesn't officially kick off for the next 2 days 7 hours this project is slow to validate work so if you start now you should have a good amount of work that is tied up in pending status waiting to validate and have a higher chance of being counted within the contest period. So simply put no need to bunker this but starting early is a big advantage.

Now in terms of the subproject that i recommend i would suggest "WW" also known as "Wieferich and Wall-Sun-Sun Prime Search"
If you edit your primegrid preferences you can set it to not run on CPU and then only select the appropriate "GPU" flag for your particular video card. Doing this will ensure that primegrid only runs the GPU on your rig and that leaves you free to continue running SIDock CPU tasks at the same time!


Once you have signed up for the primegrid project if you go to the "My Account" page on the site you can go to "primegrid preferences" and edit your default preferences to set this up.

In the upper part of the preferences you want to make sure "CPU" is unchecked and then to check the appropriate GPU type for your rig (AMD or NVIDIA) like this:

455113_1620233088273.png



Then lower down is where you select the project so here is an example of selecting it to run on NVIDIA GPU's only. I would double check that you don't have checkmarks in any other sub projects besides this one and that you don't have a check to allow work from other subprojects if there is no work.

455118_1620233490407.png



Other than WW subproject you can also run PPS Sieve as it is also another GPU project that scores very high points, but I think most people are gonna pick WW.

Once this is done and primegrid is added to your BOINC client the last thing is to make sure that your BOINC client setting allow GPU work to run.
Let me know if anyone has questions on this. I am already setup and processing WW work since about 30 minutes ago and most of it is in my pending so I hope to have a good head start on this.

Jeepers wrap up of day one: https://www.seti-germany.de/forum/list/category/3-BOINC-Pentathlon


Day 1 - 05 May 2021 - Off of the starting blocks​


Do you know the feeling when you can finally enjoy something which you had missed for an eternity? The cold beer running through your throat, going for a walk for the first time after corontine, or the view at the Pentathlon charts?

It is indescribable. Everywhere I am looking into the faces of the Pentathletes which are enchanted with this incomparable sweet and fine smile. I am glad to be able to hack away at the keyboard again, and with a clear head now, energy flows through my fingers, like it does through the processor cores too.

27 teams went onto the marathon track today, which I will turn to in a minute. Team China is back on board, which I like a lot, because the red dragon is always a medal aspirant.

The next discipline is already known. Javelin Through starts tomorrow with the first throw. Those who do well here and have nerves of steel will be done with just three throws and can save power for the other disciplines. But this can backfire too. In the past years, the teams confronted us with different tactics; let's see who has got the strongest throwing arm and the best tactical skill.

Marathon (SiDock @ home) = Overall Standings
Since Marathon is still the only discipline showing on the scoreboard of this year's Pentathlon, Marathon standings and overall standings are identical. Tomorrow this may and will look different, notably due to different tactics at Javelin Throw.

Every so often during the past years, there was a team with a hell of a good start and a huge lead. But this time it's different. Planet 3DNow! (P3D) placed themselves at the top of the field. 5x Silver and 2x Gold is the track record of the Green Planet at Marathon so far, and apparently they intend to follow through again this year. But the lead is not too large, and it is possible to catch up with them.

TeAm AnandTech (TAAT) try to match the pace and are holding Silver rank. Last year they could scoop a complete set of medals in disciplines, although they left the marathon empty-handed. This seems due to be changed this year. Behind, SETI.Germany (S⁠G) are holding 3rd place. A surprisingly good start for the German team, let's see if they can keep it up.

Because danger lurks from The Scottish Boinc Team (TSBT, # 4). The sweetly smelling breath of a good single malt may already have reached SG. Does this track them on, or cloud their senses? We will see. Maybe we will have a whiskey and beer soon.

There is an already larger gap is widening behind them, which is certainly surprising. What's more, it were LinusTechTips_Team (LTT, # 5) who allowed this gap top open. Last year, Marathon with Bronze was their highlight of the Pentathlon. Now they need to be careful not to stay behind.

In LTT's slipstream, there are In Science We Trust (ISWT) running at # 6 and Czech National Team (CNT, # 7). It is still hard to tell how the rookies of ISWT will fare, whereas the Czechs were often seen in these regions of the marathon in previous years. But good to see a new team already stirring up the top ten.

There is a duel afoot about # 8. L'Alliance Francophone (L'AF, # 8) and Rechenkraft.net (RKN, # 9) are closely spaced. The pace of the duo is not sufficient to stabilize the gap in front, on the contrary. We should not count out Ukraine (# 10) and BOINC @ AUSTRALIA (# 11) here, nor Overclock.net (OCN) at # 12 and [H] ard | OCP ([H]) at # 13. Although the pace of OCN was not particularly good in the last hour, this may change any time, like [H] have shown just now, making some ground.

BOINC. Italy at # 14 look to have a little break with wine and pasta, by which Chinese Dream (# 15) apparently let infect themselves too. This is a chance for AMD Users (# 16) and Crystal Dream (# 17) to catch up and snag themselves some pasta and wine along the way. I wouldn't put it past BOINC @ Poland (# 18) to do the same, but right now I am not recognizing
sufficient motivation there.

After that, LITOMYSL (# 19) are breaking a sweat, because Meisterkühler (# 20) are stoking the boilers and are catching up, and detached from Team 2ch on # 21 too. Crunching @ EVGA (EVGA, # 22) and UK BOINC Team (UBT) on # 23 are following.

Rank 24 is secured by BOINCstats currently, followed by Team China (# 25). So far the red dragon is not very threatening, more Mushu than Smaug. This way the Chinese won't get very far in the overall standings. But perhaps Russia (# 26) can tickle the dragon to wake up. The Russian bear is still in hibernation though, and so his walk still looks quite clumsy. The last place is taken by BOINC @ Pfalz. Somehow they seem to got lost in the wine cellar.

What are the first hours telling us? Besides very well known ones, four teams seem to detach themselves from the field. The other teams have to be careful here not to miss some crucial points already early in the race. The weakness of the Chinese is still a puzzle. Even though the marathon course is still long, experience is showing that big jumps towards the end are rather rare, also considering that other disciplines will divert forces. And this is what we will see tomorrow:

- Who will let the javelin fly the furthest?
- Can P3D maintain the lead on the long distance?
- Will TSBT make it onto # 3 at the marathon with stunning tactics?

You see it remains exciting at the BOINC Pentathlon.

Yours, Jeeper
