I think its restricted to linux 64 bit machines

Whay it download app if it is restriced. It not find x86 opencl file because folder locations different in x64

App itself not get opencl file info because it look it another place but it not look it on both folders.
Boinc itself detect x64 file but we needed 32bit one. Drivers supply both files.

3 gentoo 64bit boxes all with the same problem and they are crunching openCL wus for poem and primegrid - exit with code 255 - unable to get openCL info - error -1

FYI, those projects don't use BOINC's OpenCL features at all. As far as I know we are the first project trying to get a fully BOINC-compliant OpenCL implementation going, including OpenCL device management controlled by BOINC, not the app. The error you experience is related to that and we're already aware of it and are investigating it as we speak.

HV Margus* and Trog Dog: do you have multiple GPUs in your systems or just one?


Cheers,

I have no idea whether poems app is a fully boinc compliant app, but they certainly use the boinc opencl detection features - as stated in this thread - to be able to get and run the opencl app you need a 7.0.x client.

As to the number of gpus each of my 3 boxes only has a single gpu.

May I suggest that you release a 64bit opencl app, if that works (at least detects the opencl features) then the problem lies in the detection of 32bit capabilities on a 64bit machine.

Ok, fair enough.

Ok, thanks.

Not anytime soon due to our current time constraints. However, there are successful results from 64-bit Linux systems, so it's not a general issue.

For those of you on Linux who have the AMD APP SDK installed alongside the AMD Catalyst drivers, please make sure you follow the order as details in the AMD developer release notes (chapter 2).

HTH,
Oliver

There is no needed anymore APP sdk Because 11.12 and 12.1 catalyst supply all sdk OpenCL files. Whay the poem@home work it is opencl too. Installing top 12.1 catalyst the APP SDK broke the system. I test that stupid thing installing SDK then 12.1 as they say that.


Still no go i dont know what dodo. Installed app sdk 2.6 and then a catalyst 12.1
<core_client_version>7.0.14</core_client_version>

Unit 1
Unit 2

I don't have the SDK installed, one box has Catalyst 11.12 and the other two 11.11 which provides the opencl drivers. I also have 32bit version of libGLU.so installed as mentioned in the developer release notes.

Maybe we can get some feedback from those successfully returning results from 64bit linux machines with ATI/AMD gpus.

Just found out that 12.1 was released as an unstable package a few days ago so I've installed that on all my boxes now and 1 is happily crunching away on an opencl wu

How do you installed it. I use this. http://wiki.cchtml.com/index.php/Ubuntu_Oneiric_Installation_Guide I make debs and install then.

My boxes are gentoo, all I had to do was unmask the unstable package and compile it.

It is pain to do this but maybe this help http://en.gentoo-wiki.com/wiki/Fglrx

Can you try ubuntu on these boxes or it look a pain. Ubuntu is simple then others.

First successfully completed opencl wu http://albert.phys.uwm.edu/result.php?resultid=109919

@HVMargus - thankyou for your help. I don't use ubuntu, but this may help you - remove the SDK then follow the instructions in the wiki for removing older versions of catalyst, then reinstall, configure and reboot (gentoo always recommends rebooting after upgrading catalyst)

Guys, we just released v1.21 which adds some useful debugging info to the task/result error log. Please reset the albert project or wait until the next task is fetched. The log output of those tasks will help us to understand the problem.

Thanks,
Oliver

Great, so it turned out that the installation was flawed, most likely because of missing 32-bit compatibility libs.

Anyway, I hope we see at least some of those errors again on other systems as we'd really like to understand them and make BOINC more robust for these types of situations.

@HV Margus*: Please run at least one or two tasks before you fix your driver setup. This would really help us! Thank you!


Best,
Oliver

Oliver i installed ubuntu supplied ati catalyst it is 12.1 but its missing opencl
Uninstalling ubuntu supplied catalyst lead missing gl.conf files and unable to go to previous drives as i used before. I try to install sdk because system is missning opencl and boinc not detect opencl in system i have not time to test but if i back home i try things even reinstall os and go to previous state.

Installed SDK AND NOW IT WORK I LET A DAY WORK with old opencl files.

I successfully completed WUs with v1.21 app now under linux i look if they validated too.

Are you sure you installed all relevant packages? Linux distributions might often split the original/upstream driver installation package into separate packages like the kernel module, the user space driver, the OpenCL runtime and the OpenCL ICD. Debian does this and Ubuntu could do it in a similar way since it's based on Debian.

Good to see that it now works for you!

Cheers,
Oliver
