1) Message boards : GPUs : PC with two GPUs (Message 99832)
Posted 19 hours ago by robsmith
Post:
You can select which class of processor each project uses, and this is done on the project website.

WCG:
go to https://www.worldcommunitygrid.org/ms/device/viewBoincProfileConfiguration.do?name=Default
then scroll down and make sure you've only selected the CPU projects by unticking the "If my computer can process work on my graphics card, then please send me work to run on my graphics card for the projects that I have selected above." option
and possibly the "Please opt me in to new projects as they become available."
Then save the changes

Rosetta:
go to https://boinc.bakerlab.org/rosetta/prefs.php?subset=project
Click on the first "edit preferences" button and make sure that "Use CPU" is ticked

Save the changes

Einstein
Go to https://einsteinathome.org/account/prefs/project
Tick which ever GPU family you have, and untick the "use CPU" option
There's a whole load more options lower down the screen - most have some description against them, but two you may want to say "no" to are "Run CPU versions of applications for which GPU versions are available"
and "Allow non-preferred apps"

Save the changes.

In each case the changes will probably take a few hours to work their way through.

One thing to be aware of is that if you have two different GPUs from the same manufacturer (say a GTX980 and an RTX2080) in the same computer only the more powerful one will be used by default - overcoming this means editing a file, but if that's needed we can go through that another day...

Read the very first post in this thread as that gives the answer and a link to the official post on SETI from SETI

One of them is keeping busy rebuilding the back of his house. By the back I mean knocking things to bits, building new bits - and making sure the coffee machine is still working.

Just tried the your link, and accessing the WCG forum directly - it looks as if they are having some issues just now as it's not possible to access them just now :-(
5) Message boards : Questions and problems : Boinc 7.16.6 and up, memory issues (Message 99413)
Posted 16 days ago by robsmith
Post:
As detailed memory management is in the hands of the application developers I think they would be most interested in your observations. Remember BOINC doesn't look after the memory that any application uses so it is probably worth raising this with the relevant applications.

Rosetta has selectable run times in the range 1-12 hours (I think that's the range in which you can set). Which is far shorter than those of CPDN which are measured in days. In part the reason for CPDN's long run times and hence long deadlines is to allow for slower machines, but also the tasks are designed to be able to safely swap out periodically, so they can sit dormant for days, or even weeks without causing any problems.
Resource sharing is a long term thing not an "instant average" - it can take weeks, if not months for BOINC to sort things out, particularly if you have a large work cache and one project has no work to send out. As has been said having a small cache work better than having a large one - I run 2 or 3 days plus an extra 0.01 which works for me (WCG + CPDN) provided there is a steady flow of work available from both projects. Just now (and for the last few weeks) CPDN hasn't been sending out work, I suspect this is in part down to the fact that the Uni where the servers are based (controlled from) is in lock-down just now.

Just now CPDN doesn't have any tasks to send out, which does make it a bit difficult for BOINC to do any sensible resource sharing

There used to be a number of combined fan and filter systems around, but they all appear to have been replaced with separate units. :-(
The best solution looks to be a 120mm fan plus a 120mm filter unit. Given the filters are only a few mm thick with the same mounting hole location and size as the fan you could either sandwich the filter between the case and the fan, or on the outside of the case, if being used on the input side of the case; otherwise just put the filter directly onto the case (you might need a few nuts and bolts or fan mounting plugs, but they are easy to get hold of at the big box shifters over here in the UK)

Thanks Gary - I knew they had a vibration/shock issue and assumed it was the camera as this has happened previously.

They've had that issue before, basically the camera gets knocked off air due to noise and vibration levels and they have to remote onto another camera (after searching through the other camera feeds until they find one that works)

That is based on the checkpoint interval set in BOINC, not the real interval from within the application - it's just a "guess", not reality.

Thanks, you've thought about it for a few days and parked it.
Learning how BOINC is put together is not a five minute job as the structure and annotation is very variable, some is well structured and well documented, while some is a "bowl of well chewed spaghetti".

Posted 30 May 2020 by robsmith
Post:
Checkpoints are determined by the person that wrote the application, and their visibility to BOINC is solely in their hands. The applications that I've looked at work on a hybrid of time and progress, using the BOINC provided "time between checkpoints" as a rough guide, not an absolute figure. Many actually control the write to disk themselves and don't actually tell BOINC that they have done so.
17) Message boards : BOINC Manager : Unfinished Tasks Question. (Message 98896)
Posted 30 May 2020 by robsmith
Post:
Which projects are you trying to run?

Are there any error messages?

What is your hardware?

The answers to these questions will help others workout the most probable answers to your question.

In general BOINC will sort out the scheduling of tasks being run so that all the tasks on a computer will finish before their due date and that can result in tasks only being partially completed before they are suspended, and tasks which are due in the very near future running to completion.



A little bit of nomenclature to help you understand what is going on:
BOINC - The environment in which a number of projects can be be run (it does a lot of background work, but let's keep this simple just now).
Project - A science project which distributes an application and tasks to a host.
Application - The program that actually does the calculations.
Task - A little bit of data that the project sends to you for the application to work on to provide a result back to the project.
Host - A computer that is working on one or more tasks from one or more projects.

If you look at the server lists for main & Beta, apart from the server names there is one big difference - Beta lacks the SETI@Home science database. Beta has been used to test/develop new server code as well as the applications, but those have always either been replicas of, or sub-sets of the main database.

Beta has NEVER fed data into the main science database, despite what some people have thought and said. Much of the work it ran was either a standard set of data, or re-badged completed data, and it is this that may have caused the confusion.

Beta does NOT contribute to the main science database, it is there to test things.
