1) Message boards : Number crunching : Rosetta requesting new tasks for NVIDIA? (Message 76570)
Posted 31 Mar 2014 by transient
Post:
It's not Rosetta, it's BOINC that is requesting tasks for your GPU. Because of the design of BOINC it is not possible to disable a device, for which the project does not have an application, so simply ignore those messages, you won't get any GPU WUs from Rosetta regardless of how often BOINC asks for them.


I have a cc_config.xml file with, among others, below options. And that works for me.
<cc_config>
	<options>
		<exclude_gpu>
			<url>http://boinc.bakerlab.org/rosetta/</url>
		</exclude_gpu>
	</options>
</cc_config>

If you decide to go that way, remember it has to be saved as a .xml not a .txt file in the main BOINC-location for data, not in the projectsboinc.bakerlab.org_rosetta folder

Maybe, I think a bigger problem is the way granted credits are calculated. I imagine that part is quite a big modification to the server software.

A more recent version of the server software would show links to filter pending, valid tasks and more.

It is why I expressed my support for the idea. :)

That is only possible with the later versions of the BOINC server software. Depending on how extensively the server software has been modified by a project, it can be a very labour intensive process to upgrade to a newer version.
The Rosetta people might think it is not worth it. I too, would like Rosetta to make the effort to upgrade their server software. But I suspect it is not high on their to do list.

It shows less than 2 hours CPU time. Didn't the old and trusted method of exiting and restarting BOINC not work?
9) Message boards : Rosetta@home Science : Quantum computing and Rosetta (Message 75024)
Posted 1 Feb 2013 by transient
Post:
I think quantum computing is almost certainly not something that will be done on a desktop. It is not some fancy GPU-gizmo. And as far as I know, the creation of an actual quantum computer is not really near. 20 or 30 years into the future, maybe?

Anyway I can't imagine it being on Rosetta's roadmap in any way shape or form. But hey, I'm not really following the subject myself. I could be totally wrong.

Post:
I think I've said this before, and I'm going to say it again. :)

Since the problem seems to be with the GPU, wouldn't it be an idea to test a version that doesn't use the graphics or prepare data for the GPU? It might help.

Post:
Like stated a few messages before, it could also be due to the hyperthreading in modern Intel CPU's. And maybe the sharing of FPU units on AMD processors, the latest phenom processors do that if I remember correctly, could cause contention for resources. There could also be contention for other resources (memory) on a PC.

Wouldn't it be better if the BOINC manager ran the benchmark on all available (logical) CPU's instead of the one CPU it uses now? Or does it do that already?
That way contention for resources would be taken into account too, sort of, when running the benchmark.
12) Message boards : Number crunching : 3.43 is causing pop-ups (Message 74442)

Hi, (sorry I am a bit of a techno-moron)
Is someone up to doing a button by button guide on how to end this.
Thanks


It's not very technical, but here we go!

This has to be done from the BOINC manager. As a techno-moron , <wink>, you're probably using the "Simple view". Aborting all the version 3.43 tasks is almost certainly easier from the "Advanced view".
- Go to the View menu in the menu bar and select "Advanced view".
- Below the menu bar you'll see a number of tabs, click the tasks tab.
- You'll see two panes in this tab. on the left pane click "Show all Tasks"
- Now you'll see in the right pane all the tasks on your computer. It's pretty straightforward from there. Select all the Rosetta tasks that show a version number of 3.43 in the "Application"-column. Only select tasks that show a status of "ready to start","waiting to run" and "running".
- On the left pane click "abort". That is the 4th button from the top of the pane.

You can do the selecting of the tasks one by one, clicking "abort" each time.
You're done. What is left for you, is closing the screensaver pop-up windows.

ALTHOUGH it DOES work for some people, not many, but a few people do seem to be crunching with version 7 AND getting credits.


I understand your frustration but,I think you should be careful when making sweeping statements like that. The fact that a person does not run into problems when running version 7, does not mean they will post about it on the forum. Almost by definition the people who post here experience a problem.

The project might be able to make a statement on how many people attempting to run version 7 run into problems with that version. 7 Out of 10 people in the top ten appear to be running with version 7. Besides that it does not mean all their hosts run version 7, it does also not mean the other 3 people attempted to use version 7 and failed.

You could try a detach/attach, or a reset of Rosetta from the projects tab.

Edit: I see you got a new result in. Hopefully everything will go smoothly now.

Another possibility could have been that your firewall blocked the transfer of the result file.

Post:
Checkpoints: They are only guaranteed to occur when a model within a task is generated. As far as I know the percentage of a task completed doesn't guarantee a checkpoint.

The results link you're referring to (that does not work anymore) only shows a graphical representation of your results. I recognise the error and I think that is the link you're writing about. For debugging purposes you need to check the tasklist for your computer. Click on the link next to tasks. Since you don't have any running or finished tasks yours is empty.

No tasks. That is the difficult one. I don't know why you're not getting any. It could simply be a case of BOINC running other projects to pay off debt. Or maybe you have Rosetta suspended in the projects tab.

I use 7.0.28 (Windows 7). I also crunch for a GPU project (Einstein) and I see only the in my view regular problems, bad batch of WU's (?), on Rosie. Could it be a RAM problem? Usually only 50-70% of my memory is in use for the entire PC. Maybe that accounts for my lack of problems?

Posted 22 Aug 2012 by transient
Post:
You could set the interval that BOINC is allowed to write to he HD higher. the default is something like 60 seconds, you could change that to for example 600 seconds. It doesn't prevent BOINC from writing to HD if a checkpoint is reached, but maybe it will limit the other write operations to the HD somewhat.
20) Message boards : Number crunching : Why does r@h use 3 cores when i told it to use two ? (Message 73581)
Posted 7 Aug 2012 by transient
Post:
You can set up different venues (home/work/school/default). This way you can use up to 4 different set-ups for your computers. Anyway you can use a local preference by going to tools>computing preferences in the BOINC manager. This might also be the reason 3 cores are used instead of 2. The local preferences, if set, override the net-based preferences. In the event-log/messages tab you should see a message if this is the case.
