2) Forums : General Topics : For the betterment of BOINC (Message 21487)

Hi BOINC Community,

Last week Richard Haselgrove and I were asked to join a BOINC Work Group committee which researches how BOINC can be made more user friendly, easier for anyone to set up their own short- or long term project, and for the community to join in on those endeavours. The goal is to get more people to run BOINC, to join in coding all parts that make BOINC (client, manager, web site, forums, projects, etc.), to test everything, to get them to set up their own projects, to make BOINC a future-proof and reliable brand that isn't dependent on any one person in particular.

We do know this is a big order and it won't be solved in a couple of weeks. So we'll work in the background together with some key people from projects/code developers to get things started. Eventually we will need answers from you as well, probably on a lot of things. But we'll start slow with a couple of small questions:

1. If there is anything at all you can change in/withdraw from/add to BOINC, what would that be? While we don't exactly look for enhancements or bug squashing, you may just let out anything you think would put BOINC on the map. For example to add social media inside BOINC Manager, or have certain add-ons integrated into the client (I am making these up, they aren't on the list (yet)).

2. Would you like to contribute to making BOINC better, or program for it, or walk the source code, or do anything to help the project forward? What has held you back thus far?

3. We'd like to get into contact with people who programmed for BOINC, but no longer do. Can you PM me or Richard on this, or contact me via email? Especially if you're one of the people in the Volunteer Developers section here.

4. We also like to get into contact with people who now voluntarily program for BOINC. Can you tell us why you decided to work on BOINC, how difficult it was to get into and what we can do to increase your involvement?

With thanks for any answers you have,

Richard Haselgrove

Hi everyone,

On behalf of the organizing committee, I want to extend a warm invitation to all members of the BOINC community to join us at the 2017 edition of the BOINC Workshop, taking place in Paris at the Institut d'Astrophysique de Paris this Sept 6-8. The workshop will be an opportunity to reflect on lessons learned from existing projects, to discuss the status of BOINC and the community, and to plan ahead for the future. For many of us, it will also be a great chance to meet in person and get to know our fellow collaborators and interested parties of this open source project.

There is no fee to attend, but you do need to register on the website below. Please do so at your earliest convenience if you would like to come. If you need an invitation to obtain travel documents to France, please don't hesitate to contact us.

Also feel free to circulate the following flyer around, or point others to the workshop page https://cern.ch/bw17



Hope to see many of you there!

For <max_ncpus>, I mistakenly put it back in the example app_config.xml file I posted in my original post. I'd taken it out, but then copied your contents with the indentations, and forgot to take it out again. Sorry for that confusion, I have edited my post to take it out.
It would seem according to that referenced BOINC documentation, that the <avg_ncpus>x</avg_ncpus> option in app_config.xml provides the same intended limitation as does the <max_ncpus>x</max_ncpus> option in app_info.xml. I suppose regardless, though, if indeed <max_ncpus>x</max_ncpus> isn't [yet] an option in application configuration, app_config.xml, but rather only in anonymous platform, app_info.xml, then a change to the FAQ needs to be made immediately.

Which FAQ are you talking about?
If the entry about the app_config.xml file in the User Manual wikipedia page, <max_ncpus> isn't referenced there and doesn't need to as it isn't used there.

How did you make the app_config.xml file? I suppose in Notepad?
Did you save it in ANSI encoding format, as opposed to Unicode or UTF-8?

<max_ncpus>1</max_ncpus> isn't an option in application configuration app_config.xml. Instead, it's an option in anonymous platform app_info.xml.

Of course, what we can also try to do is fix CreditNew. One of the people who knows how the code works and where it is going wrong is already in contact with Marius over this. Perhaps it's fixable. Wouldn't that be a treat?

Because when it can be fixed, that would mean all projects can benefit, with all giving out comparable credit and then you don't need to have to give out more fixed credits than the next project, just so to make sure that the volunteers with their computers stay with your project.

Reading the announcements may provide information but I don't see why, like ,ost of the projects, annuncements with links aren't posted through Boinc Manager.

Only items posted in the News forum will show up in the Notices of BOINC Manager, although this doesn't work that way on all projects. But by default, without admins editing their forum software by hand, News == Notices.

In your computing preferences check Leave non-GPU tasks in memory while suspended. This will leave tasks that haven't checkpointed in memory until switched back to them.

Exiting BOINC will still lose the progress.
If you're using local preferences, make sure to add this there.

Posted 3 Nov 2015 by Profile Ageless
Post:
That's not something for Cosmology@Home to fix.
In the least, (register and) post about it on the BOINC forums, in the GPUs forum. You may want to try to old stickied threads there telling how to get the GPUs to be recognized on older versions of your distro.

But in the end it always boils down to one thing: drivers.
Either the drivers are not right for your distro, or they load too slow and BOINC too fast (easily solved by waiting 10 minutes for the OS to completely start, X to start and then (re)start BOINC.)

Post:
Rebooting or restarting BOINC won't help here.
Instead, try this first: right click on the BOINC icon in the system tray (next to the clock), is there a checkmark on Snooze? If so, uncheck it.

Else open BOINC Manager, (View, Advanced view), Activity, if these are set to any other than "based on preferences", change to "based on preferences".

If it says specifically "Task suspended by user, select all tasks that say this (hold down Shift or CTRL, while clicking all tasks stating this) and click the Resume button. The Suspend/Resume button always shows the option you have, not the state it's in.

If it fixed itself in the mean time, it was Snooze. Snooze only suspends everything for an hour, after that it'll continue.

That's a bug in either the client or the server software that the BOINC Devs are still trying to get fixed. You can try a project reset or two, to see if that fixes it, and else go back to a previous BOINC version for now.
13) Forums : Technical Support : New Tasks? (Message 8466)
Posted 3 Jul 2009 by Profile Ageless
Post:
Other than to make sure you did not inadvertently put Cosmo on No new tasks or Suspend (Projects tab, select Cosmo, if a button shows in the left menu called either "resume" or "allow new tasks", click it. These buttons show the option you have, not the state they are in.

When these buttons show as Suspend and No new tasks, leave them be.
Then it's most probably a debt issue, whereby BOINC is paying back time that Cosmo has taken up on CPU time, to the other two projects. Just wait patiently, eventually it'll ask for work again.

If you can't wait and you have a pretty fast internet connection, reset the project. Resetting a project will delete all applications for this project, including any work you still have left over, are uploading, or is waiting to be reported. It will also set your debts to zero and the task duration correction factor to 1 (one). But use resetting the project only as a last measure.

BOINC works by debt. It will try to pay back the amount of CPU time that you spend on one project equally to the other projects you are attached to, based on the amount of debt it has per project, resource share of those projects etc.

Does your BOINC even ask for work for Cosmo? Can you post some messages from the Messages tab showing a contact with the project?
What is the status of the project in the Projects tab?

Posted 3 Jun 2009 by Profile Ageless
Post:
I thought the cosmology@home server sized up everybody's computer, and therefore knew how long it would take to complete WU's. Why the discrepancy?

It's the client on your computer which learns about the tasks, not the server. Work is released with a 'standard' estimate of floating point operations that the work will do.

The client compensates for differences in estimated time with the duration control factor (DCF), but it will only do so in the estimated time column after one task has been completed. Then the DCF is updated and any next work will show the new estimated time to completion.
16) Forums : Technical Support : I Have Too Many Tasks! (Message 8385)
Posted 31 May 2009 by Profile Ageless
Post:
There are three fundamental problems here.

1. You have a whole new BOINC (6.6.28) which doesn't know anything about the completion times of the project, so the estimates given are those by the project. They will be way less on your computer, if at least they run... But since BOINC can't learn about them as they err, all the estimates will only be the initial ones.

2. The maximum daily quota is 200 per day per core. Since you have an i7 with hyperthreading on, that's 8 cores, that's 1600 tasks per day.

3. At this moment you mostly have download errors. (Some aborted by you)
<![CDATA[

WU download error: couldn't get input files:
<file_xfer_error>
<file_name>params_042909_094545_6.ini</file_name>
<error_code>-224</error_code>
<error_message>file not found</error_message>
</file_xfer_error>
</message>

There has to be a fix for that first (by the project!) before you can truly let it rip.

Since Cosmo isn't the only project you've attached to this i7, I'd advise you to put the project on No new tasks first and only test once in a while to see if it's fixed.

I sent Anshul a couple of screen shots from my computer, showing one task taking up 1.24GB of memory (647MB RAM + VM + 'normal Windows stuff' loaded). His answer to me:

It looks to me like WUs for 2.16 have high precision floating point calculations. I will speak to Scott since he released this new version a couple of weeks ago. I may be able to refine the code enough to reduce the memory usage but I cannot guarantee anything. If this keeps happening we will split the work load for each workunit in 2 and maybe run "Half" universe simulations per WU.
I'll keep you posted.

I don't know how to check my memory or swap file, I don't even know where the swap file is located under Linux.

Which Linux distro do you run?

I followed the Memtest link but when choosing what to download there I am at a loss, too.

From what I've seen, most of the distros have the option to run Memtest from either Grub, or from a Live CD's first menu. It must be run from outside the operating system at all times.

I bet I should stop crunching with Linux... it's fine when having no problems but I hate trobleshooting under Linux. ;-(

I am not going to tell you to stop running Linux. If that's what you wanted to read. :-)

Check the other options in that FAQ. It may be a problem with your memory or swap file, especially if the computers those tasks are sent to now can finish those tasks without a problem (thereby scratching bad batch of tasks off the list).

Of course, it can still be a problem with the Camb binary, I am keeping that open as an option.
