8th Annual BOINC Pentathlon: 5th May - 19th May 2017

hanluc · 9 Apr 2017 at 20:46

Hi OcUK - Overclockers UK,

less than ten months have passed since the seventh *BOINC Pentathlon* came to an end. Now the Pentathlon is back to its usual date *from May 5 to May 19* and SETI.Germany invites all BOINC teams to compete in five disciplines at five projects for the eighth time.

This year, the stable and popular project World Community Grid is set for the City Run discipline, with only one subproject being considered for the Pentathlon.

The teams may enter their favorite WCG subproject and three additional project suggestions while signing up using the using the registration form at https://www.seti-germany.de/boinc_pentathlon/anmeldung.php until *April 27*. The suggestions will be taken into account in the project selection as described at https://www.seti-germany.de/boinc_pentathlon/25_en_Disciplines.html.

All information about the BOINC Pentathlon is available at https://www.seti-germany.de/boinc_pentathlon/, while you can find the answers to many questions at https://www.seti-germany.de/boinc_pentathlon/27_en_FAQ.html.

Looking forward to seeing you again at the Pentathlon!

Regards

There are 4 drop down menus with the projects lised. WCG has been decided for the last one, so for that it's just the sub project we choose.

cpu rather than gpu based would give us a better chance

There will be at least one GPU project.
Explained here https://www.seti-germany.de/boinc_pentathlon/25_en_Disciplines.html

hanluc · 21 Apr 2017 at 14:23

We've got until the 27th to add our project suggestions, 2nd May is the deadline for entry.

So far we have just one

NFS@home.

I like numberfields@home, think the admin guy there is really on the ball.
I think also collatz for gpu

Anyone else got any other suggestions?

hanluc · 21 Apr 2017 at 15:22

Personally I like maths projects, but each to their own.

It's been Announced that WCG will be one of the projects, with a choice of either
Fight aids, openzika or mapping cancer markers being chosen.

Rossetta is not an option as it was ran last year. I don't think that GPUgrid being Nvidia only is not a good candidate and Denis I'm not sure can handle the work. If there's another shout for it I'll add it to the consideration list. We need to pick 3, and one WCG sub project.

Asteroids
NFS@home
Pogs
Einstein
Cosmology
Collatz

I can do GPU stuff but I'll not be able to do much CPU stuff, she gets a little toasty.

Brilliant, thanks!

hanluc · 30 Apr 2017 at 05:14

The marathon & city run projects have been announced!

See post #1

It starts in less than 5 days!

No gpu then lol

Only two of the 5 have been announced so far.
Cross Country is usually the GPU one.

hanluc · 1 May 2017 at 12:48

I don't know what the something else is but that app_config you posted is set to run 2 works units simultaneously running 4 cores on each, so 8 threads in total.

Try 2 x 6 see if it uses less memory.

Plank credit is 50 pts flat if i remember right.
Camb_docker has a mind of its own when it comes to credit.

hanluc · 1 May 2017 at 20:43

You're doing better than me, trying cosmology now with with Vbox and on both camb_docker and planck my CPU usage is a big fat zero.

hanluc · 1 May 2017 at 22:28

I got it working, uninstalled the VB version that came with boinc and install the latest version, it still didn't work after that but it is now. I probably haven't got app_config balanced right, but I don't care, It's working, what with me hosing a days worth bunkered openzika work units trying to get multiple clients on linux I just want to have a rest from it now, I've been prating around on it most of the day.

..& good luck to you and your team too Tony.

hanluc · 2 May 2017 at 15:16

We seem a bit thin on the ground here

From what I can tell, those in the pentathlon are:

PDW
Andy Taximan
ozaudio
MGP
Senture
& myself

Acme said he would help with GPU stuff

Anyone one else helping Team OcUK in the pentathlon?

have you sent any reminders out Oz?

hanluc · 2 May 2017 at 22:05

Be careful anyone trying to bunker openzika on linux the way i tried.

As I already said, I lost a days bunker when the client became detached, trying to run multiple clients.
So this time, after I bunkered up again, i pulled the SSD out, and installed a HHD. I made 3 separate partitions on this disk, and installed 3 separate instances of Ubuntu on each partition, each with a different computer name.

Booted into the first, downloaded zika work, then shut down & booted into my 2nd instance, downloaded zika work, but the server didn't recognise my second instance as a different machine and subsequently it detached and aborted all my work units from the first instance.

I panicked a little and thought the SSD I pulled from it might have been hosed to, but thankfully it wasn't. I can only guess that it was because they were on the same disk? don't know, but I'm done bunkering WCG now.

MGP said:
Did you start boinc each time as a completely new client machine, or did you try and retain any part of it's identity so that your client would have been seen as trusted? If you kept the boinc identity others have reported that something is buried in the client and/or server that tells it that you already have WUs downloaded, but of course it can't then find them, gets confused, and you are in a world of hurt.

I started them each time as a completely new client machine, with different computer name. What would happen is the first machine was called, let's say, rig1, it would show up as rig1 at the WCG, but when rebooted into the other OS, and run rig2, rig1 would be renamed rig2.

hanluc · 3 May 2017 at 00:43

I've checked the Linux machine-id on each box and they're all unique.
I didn't lose any work , I loaded up the first then went straight to the second one to test, good job i did.

PDW said:
Not sure what you mean by 'machine-id'.
Computer ID is the unique number given out by a project for each client, some projects are strict and will only give 1 Computer ID per computer.
WCG allows separate Computer IDs for each client, so not strict.

Sorry, I thought you meant the ID generated by the OS. I can see the different ID numbers on "normal" boinc projects but not on WCG? just the device name.

Do you still have both the rig1 and rig2 listed as separate Computer IDs in your list of computers at the project (whatever the 'rigX' number might be) ?
The name of a client (eg rig1) in the list of computers does not have to be unique.

Although I can't see the IDs they have to be the same given to rig1, rig2 & rig3, because they are never listed as separate device names. On the results status page, from the Device Name drop down menu, I can see rig1, if I now reboot into rig2, rig1 gets renamed to rig2, the server thinks they are the same rig and detaches the work units it gave me before (which are on rig1) because it sees them as not being there no more.

I have the latest recommended version of Linux 7.2.42, though it is old (Feb 2014) The only newer version is a development one, but again it's old (Sept 14) But now I know what I'm looking for I'll give it a go, but only AFTER I've uploaded, I daren't try it now.
Thanks.

I'm wrong they aren't the lastest Boinc versions, BOINC development doesn't build BOINC anymore and my Ubuntu distro is old and that's the lastest version in the repo, I'll need to upgrade if I want a newer version.

I don't have time for games, just going to run things as they come up and contribute where i can.

Are you keeping your cards on f@h?
Einstein is GPU and needs to be validated by another user, you could hit that now if you are so inclined.

hanluc · 4 May 2017 at 19:46

It starts in 4 days but the point I was making was the work units won't validate straight away, so if you started now you'd be more up to speed when it actually does start, just a suggestion.
I take it they're the camb_legacy ones, not ran them, camb_docker are reasonably short but require virtual box.
