We just released 5.8.x, so I’m sure there are a lot of questions out there.

Ask away…

Have you seen this GPU programming kit:
http://www.nvidia.com/object/IO_37226.html
What do you think are the difficulties of GPU programming with this and would some work still need to be done by the CPU like on F@H?

I suspect every project would have to be a hybrid and use both the CPU and GPU. At the end of the day the OS needs to know what is going on, otherwise it would just overwrite whatever work you assigned to the GPU with something else.

To be honest, I haven’t studied the S@H or R@H source closely enough to know how easy or hard it would be to port using the various toolkits released by the video card manufacturers.

Hopefully we’ll start to see more traction in this area with the release of 5.8, since it has some basic video card detection code in it.

I’ve tried to install BOINC as a service on a computer of my fiance’s mother’s but she has no password on her XP computer account. BOINC won’t install (service) without a XP password. The obvious would be to password the account on the computer and then install but she doesn’t want a password. Is there another way around this issue?

As another later in the thread has mentioned, I would also just create a different account and let it run in the background.

http://bbugs.axpr.net/index.php is down:
DB Error: connect failed
[nativecode=Can’t connect to local MySQL server through socket ‘/var/run/mysql/mysql.sock’ (2)] ** Array

It appears to be up at the moment. although the address I have for it is http://boinczilla.axpr.net/.

boinc.berkeley.edu is scheduled for some hardware upgrades, after that it is my understanding that we’ll be bringing the bug database in house. I’m trying to get David onboard for using Tracwhich I think is pretty neat software. I’ve started using it for a pet project of mine.

Is there a fix for the next boinc version later 5.8?
ERROR: buffer too small in MFILE::vprintf() –>continuously logs in stderrdae.txt

This should be fixed now.

I need a better xml administration because all changes you get only by restarting boinc (url changing, skins etc.)

I’m not sure I understand this? Which controls are not updating on a skin change?

1) In the advanced view – Help – first entry starts http://www.rechenkraft.net/manager_links.php?target=advanced . Is it possible to configure this URL in skin.xml? i can only configure the domain.

I’m afraid we are in lockdown for 5.8, that is something we can fix for 5.10 though. Or sooner I suppose.

2) If I click with the right mous button on the icon in the taskbar (windows) and select the first entry the page bam.boincstats.com is loaded. Is this URL configurable?

Nope, when your attached to an account manager, that is their URL.

3) My skin on windows looks good, but on Mac the pictures seems not to fit. See in the middle above “Graphics Available”.
Windows: http://www.altes-beckhaus.com/cf_miko/dlc/rk.jpg
Mac: http://farm1.static.flickr.com/134/332170353_d39c4ca101.jpg?v=0

I’ll send an email to our Mac dev and checkout what is going on.

4) Would be also nice to be able to change the font color in skin.xml (for elapsed time, time remaining, application name,…).

We could introduce this in the 5.10 time frame.

5) There is something wrong with these files:
-background_image
-project_area_background_image
-dialog_background_image
-workunit_area_background_image
If the format is “.jpg” such as documented in Creating Skins the Manager shows only standard, with “.png” no problem.

Does stderrgui.txt have an entry stating it failed to load each of those images defined in your skin? It is only supposed to use the default images if wxWidgets throws an error while attempting to load the image. Which tool are you using to create a jpg file?

The current beta linux clients show about a 10% improvement in benchmarks. Is this as good as it gets, or are further improvements likely in the future?

That was from Tekwyzrd. I’m sure he and others will figure out more generic ways to speed up the client.

Any questions for this week?

During the install of BOINC as a Windows service, you are required to enter an account which will be used to launch the BOINC service. Why do you need this? I can manually convert the service over to “Local System” without requiring credentials at all and it still seems to work OK.

“LocalSystem” is a special account, it has more permissions on the system then even the administrator account.

My goal in setting up the installer that way was to try and get people to be a little more paranoid about which account they were going to use as the service account.

For instance if you use your computer to track your finances you probably don’t want to be running BOINC using the LocalSystem account. Even if you initially removed permissions from your financial records for the LocalSystem account any process running under that account can take ownership of those files and read them anyway.

We actually talked about the whole trust thing at the conference, how do we as a community know if a new project is trust worthy? How do we know their application is doing what it claims to be doing?

As an off shoot of that conversation, how do we minimize the damages a potential project can cause on a computer system? The most obvious answer is don’t run as LocalSystem/Administrator/root.

The safest way to run BOINC as a service is to create a limited user account just for the BOINC service.
