Post:
Life is different in the US so I’ll not advise you directly but here are a few questions to consider before the American contingent arrive :-)

How much are you prepared to pay in electricity bills? If you are getting power cheaply or need to heat your home anyway then you might consider older, cheaper kit.

How noise averse are you? If the computer is to live in your bedroom you might choose different equipment.

How technical are you? Is this to be a home build or must it be bought ready to run?

Is it dedicated to Boinc or do you need it to run other software?
2) Message boards : Questions and problems : How to remove projects? (Message 102952)
Posted 15 days ago by Bryn Mawr
Post:
That's what I've been trying to do. I go to the website for each project I want to remove, but there's no obvious way to do that. In particular, the NFS@home and the Citizen Science Grid. Both are giving me notices that I need to remove the project and add it back in. Citizen Science says there something wrong with my key, and NFS says I'm attached to the project twice.

But how?


Not the website of the project but the website of the account manager - something like BAM or Science United - that you used to attach to the project in the first place.
3) Message boards : Projects : How to assign profile to project on a specific machine (Message 102871)
Posted 17 days ago by Bryn Mawr
Post:
I have two Linux boxes, two Windows boxes and a 2013 iMac running or logistically capable of running BOINC projects. At present I can't get work units for CP on either the Windows or the Linux boxes; I don't know why. The messages in the event log tell me that nothing was downloaded, but they offer no explanation - and certainly nothing related to configuration issues.

By "preference" I'm only referring to machine configuration; I am totally happy with the organizations running whatever projects they wish on my machines; and that goes for CP and WCG. Thanks for guessing about how my deranged mind might work, though :-)

So only Linux projects for CP? That explains the empty WU list on my Windows boxes. Thanks for that info :-)

So... on to the 32-bit Linux issue: in my investigation I saw this morning that I needed to install 32-bit libraries on my Linux boxes (the upgrade from 32 to 64 was one of the changes I was talking about having made relatively recently). I've just done that earlier this afternoon, so it may be that I simply need to wait for the server to notice.

Thanks again for your help.


With the 32bit libraries CP blacklist hosts where they notice that the libraries are not installed and you may have to post a request on the forum for them to clear that.

The other possibility is one that stopped me from processing CP for 8 months, check you cc_config to make sure no_alt_platform is not set.

Post:
Thanks, Bryn Mawr. Yes, location-based profiles would indeed limit me that way, so I'll have to have per-machine profiling. The only issue there is that I can't customize per computer AND per project, but that's OK: Climate Prediction is the only project I run that has different recommendations to the others, so I'll probably run that on a machine that doesn't get disturbed much; that'll resolve the suspend issue.

Thanks for your response.


But you cannot have different profiles per project anyway. Things like %cpu, memory allocation, etc are machine based, not project based.

Post:
I have several machines running BOINC projects. They are all at my home, but they have different purposes, OSs and hardware configurations and I wish to use different computing profiles to them. I see that there are default, home, school and work profiles available (rather quaintly constrained and unimaginative thinking, but that's a conversation for another day), but I cannot see where to assign a particular profile to a particular machine. Where do I do that, please?


Using the location would restrict you to 4 sets of computers. If you have more configurations than this you can set the parameters at local level and vary it by computer.

At what?

It depends what you’re trying to do
7) Message boards : BOINC client : Stuck on "BOINC screensaver loading" (Message 102681)
Posted 24 Jan 2021 by Bryn Mawr
Post:
I checked my tasks regularly a couple weeks ago and it looked like they were expiring. I'll double check that though to make sure.

As far as screensavers for the remaining projects, Einstein@home project screensaver runs frequently on the gaming rig so I know that one's still active. Milkyway doesn't have a project screensaver but I still see tasks being completed when I check the manager.


So does that mean, with swap between screensavers every 1 hour, that you’ll show trying to load for 2 hours in every 3 whilst it tries to show seti and MW?
8) Message boards : Questions and problems : boinctui on pi zero - calculations fail (Message 102668)
Posted 23 Jan 2021 by Bryn Mawr
Post:
The hardware is a raspberry pi Zero running Raspbian Buster armv61
Using boinctui headless over ssh, installed from apt repository
boinc client manager version 2.5.0

boinctui runs ok, and projects can be added, they fetch tasks but the calculation completes in about 1 second (clearly some sort of failure) and then there is a message about no output file.

I've tried reinstalling boinctui and boinc-client, i've tried running with and without sudo.

these are a couple of the projects with this behaviour which I think should work:

LHC@home
Einstein@home

i've tried to find a log file but not had much luck, not really sure what i'm looking for.


As I recall the Pi Zero was 32bit and only had 0.5gb of memory both of which could be a problem. Sadly I don’t know the two projects you mention well enough to know their requirements.
9) Message boards : Questions and problems : BOINC workunit power balance wrong (Message 102657)
Posted 22 Jan 2021 by Bryn Mawr
Post:
Thank you I'll give it a try


That will also help by restricting the number of WUs Boinc downloads.

When they first download, what is the estimated time to completion? It should be 8 hours but sometimes Rosetta gets in a muddle which is why it downloads too much.

Also, go to advanced view > tools and run benchmarks. It should have run them itself but sometimes does not and that can throw the WU allocation out as well.

Post:
Hello,
I seriously think that the project workload distribution is very wrong in my case..
I have Rosetta@HOME as my only project.
I see that BOING downloads 8 work units to do contemporaneously.... I think they are too much for my machine..
I see that I often I arrive to 80 % than the system advise that they are overdue (time limit expired) and suggests to me to abort...
It happens continuously.. And the system is not capable to understand that my machine and the time I give for the prjects is too small so continues to download 8 work units...
I think that if a situation like this continues many times the system should download 5 o 4 workunits at time so to balance the power..
I seriously think that the system is wasting my current doing nothing useful..



Rosetta can take a while to learn how much work your system can deal with but there are several ways that you can help it to do so without loosing work.

In order to advise you of the best way we need to know something about your set up. What computer do you have, how many cores and what processor? What operating system and which version of Boinc?

I believe BOINC to be dead.

I'm so sad; I was a BOINC cruncher since SETI. Recently I came across a Precision T7400.

I could put 128gb RAM - albeit FB ECC PC6400 on a quad-channel board - & RAID 0 SSD into it. But why bother?

BOINC is dead.


What makes you think it is dead? Which projects are you connecting to?

As Les has said, Boinc is alive and many people are crunching at a lot of highly worthwhile projects.

Post:
I've seen similar behaviour you describe with Rosetta in the past, so "not uncommon" with that project.
I can't comment on the other projects, but others might (I hope)


With Rosetta it is not that uncommon. Rosetta is unusual in that the jobs are time limited rather than work limited. Some WUs, however run over the expected time and then the scheduler does not know how much longer the job will take so it stops at 10 minutes and hovers there until the end.

Post:
I already did this using the Core Temp program I found a link to in this forum. The temp never went over 50 C which didn't seem like it should be too hot to me. and is the same as I get when running some games on my PC which have never caused a crash.


Ok, once you’ve got rid of the very overdue Rosetta tasks, what other tasks are running?

First thought is thermal cut-out.

Boinc stresses the cooling like little else. Try install a hardware logger and look at the log of the CPU temperature for the time of the reboot.

What does the Event log show?


Sorry to be a noob - and I have searched the internet for 30 mins to try and find more info - also looked in /var/lib/boinc-clinet and /etc/boinc-client but can only find GPU detect logs and not stdoutdae.txt which I understand is the event log file? In fact I searched my entire machine and couldn't find it... must be doing something wrong.

Any ideas where to look?

Thanks,


The stdout files are usually in in home/.boinc

Should have said, I have signed-up for 3 projects and the host machine that is attached via the Windows client is running tasks.


If you list projects through Boinccmd does it show them or are they only visible in BAM?


using boinc --get_project_status just returns the title ========Projects==========


In BAM > projects try setting default attach against each of the projects. It sounds as though the projects are set up in BAM but have never been downloaded into Boinc.

Either that or take back control, use BoincCmd to attach the projects directly.

Another thing that can distort the mix of jobs and can end up with Boinc just running one project at the expense of all others is the attempt to match the credit score to the project weighting over several day’s processing.

To make Boinc settle down more quickly I set rec_half_life_days in cc-config.xml from 10 down to 1.

Installed Boinc on Debian headless v7.14.2
Ran install and changed permissions as per this page (https://boinc.berkeley.edu/wiki/Installing_BOINC_on_Debian)
Added BAM as acount manager with: boinccmd --join_acct_mgr http://bam.boincstats.com <name> <password>
Checked with: boinccmd --acct_mgr info
... and BAM is attached as the account manager.
But nothing happens... no tasks pulled down, no CPU usage.

I can see the hosts from my BAM account if I login to the BAM website. And I have another WIndows PC with the Boinc client manager and have added BAM to that machine fine.

Tried re-boot; tried restart.

Worked fine when I attached scienceunited (except I couldn't detach and had to re-install).

Odd thing is boinccmd --lookup_acct_mgr polls and returns a blank key, so not sure if that's an issue.

All help gratefully received.

Jon


It sounds like you have attached to an account manager but not attached to any projects.

The account manager only records what you have done and gives you some control over your projects, it’s the projects that give you work (Science United is an exception, it takes control over the projects away from you).

Log into BAM and select the menu, about 6 entries down there’s an entry Sign Up For Projects which brings up a list of those available.

Use the Manjara package manager Pamac (or Octopi if it’s installed) and search for Boinc, you might have to enable AUR (the user repositories) first. See :-
