Is there any chance of seeing new production applications on Brook+/CAL (ati14)? I'm a long-term user of Radeon HD 3650.

I think there is still something wrong. Here is the news:
If the percent complete is increasing at all, let it run.
The task was running almost 3 days, and the fraction done counter was slowing down (first day ~ 90%, second ~5%, third ~2%). After three days it barely moves. On Windows the "big" workunits were finishing in 12 hrs or so. boinccmd --get_tasks:

You may also want to enable your preferences in BOINC to allow computing while the computer is in use. Otherwise, every time you go to check to see how it is doing, it will show 0% utilization because it suspends itself as soon as you touch the mouse or keyboard.
Is there a canonical way to do that using boinccmd (or by any other method)? I have set several options, but I'm not sure they will imply this; these are: --set_run_mode always and --set_gpu_mode always. Still, I haven't use the computer almost at all, so the task should be at 100% by now.

OK, I'm running 64-bit Linux, unfortunately, but I've set up 32-bit BOINC client. I'm relatively new to BOINC, so I don't know if I've done everything right, but the results are somehow strange; this is my ./boinccmd --get_tasks (seems less informative than BOINC manager, but I haven't manage to set it up yet due to thin 32-bit environment):

It looks like fraction done is slowly emerging, but estimated CPU time remaining looks rather weird. After restart of whole BOINC client, the fraction done counter restarts from 0%. The process is in fact executing:
spj@ciastko ~ $ ps aux | grep solo

../../projects/boinc.thesonntags.com_collatz/solo_collatz_6.00_i686-pc-linux-gnu__ati14 --device 0
It takes some RAM (~0.5%), no CPU, but if I read GPU hardware clocks, the load stays at 0%:
spj@ciastko ~ $ aticonfig --adapter=0 --od-getclocks
Adapter 0 - ATI Mobility Radeon HD 3650

Current Clocks : 600 500
Current Peak : 600 500
Configurable Peak Range : [300-600] [500-500]
GPU load : 0%
The clock is OK, as I can start some OpenGL application (fgl_glxgears for example) and the load reaches 90% at once. Applications' stderr.txt (after one restart of the client):

I've tried running it on 64-bit BOINC client, but it seems applications hangs at 0% (stderr.txt looked exactly the same). Output of ldd:

Maybe my setup of the whole client is not OK. I'm running Windows 7 x64 on the same machine and I had a problem with SETI@Home Brook+/CAL application - it was constantly restarting the driver. The solution was to downgrade drivers to some really old Catalyst (9.x or so, one of the first versions to support Windows 7 at all). Maybe there is a problem with CAL 1.4.1734. I can do more tests on request.

Hope this post helps.

Posted 1408 days ago by Szymon Jaranowski
Hey, you asked for tests a while ago. I'm running Collatz fine on two ATI cards:
1. Mobility Radeon HD 3650 on Windows 7 x64, Catalyst 9.12 (core driver 8.681, CAL 1.4.515), http://boinc.thesonntags.com/collatz/show_host_detail.php?hostid=139480
2. FireGL V7700 (RV670 chipset, same as Radeon HD 3800) on Windows XP x64, FireGL driver (not Catalyst) 8.634 (which gives CAL 1.4.344), http://boinc.thesonntags.com/collatz/show_host_detail.php?hostid=141064

But: I'm really used to work on Linux - any news on Linux front? I'm refering to part of conversation http://boinc.thesonntags.com/collatz/forum_thread.php?id=1113 about legacy ATI drivers in repositories of modern Linux distibutions.
