Thanks Oliver. 11.11 is

Thanks Oliver.

11.11 is the latest WHQL driver from AMD for FirePro m7820.

I'm downloading 12.4a mobility and will mod, install and report back whether the problem persists.

If someone manages to get

If someone manages to get everything working smoothly on 64-bit Ubuntu 10 (10.04 or 10.10), please do let me know. I think I'm having trouble because I want to stick to these. I have tried a number of things since yesterday and I can't seem to get BOINC 7.0.27 to return that I have a working OpenCL platform / driver.

Oliver, HB .. what distribution / version of Linux have you folks been using / testing on?

Thanks,
Gaurav

Debian stable/squeeze x86_64.

Just to make sure, you have a running X server that the BOINC client can access (required by the ATI OpenCL platform)? Does clinfo return info about the device in question?

Yes. clinfo works and my own

Yes. clinfo works and my own OpenCL codes work fine. The same machine was doing fine with Ubuntu 11.04 for several months on Albert. I downgraded to 10.10 and now I can't get it to work!

Hi Gaurav, You also want

Hi Gaurav,

You also want to make sure that there is only one instance of the 32-bit OpenCL runtime library installed and in scope of our application. There might be remnants from earlier APP SDK installations that interfere with the latest Catalyst installation - a bug I already reported to AMD. You want to check it like this:
find /usr -name "libOpenCL*" | xargs file

Check which library instance gets used by our application:
ldd /projects/einstein.phys.uwm.edu/einsteinbinary_BRP4_1.24_i686-pc-linux-gnu__atiOpenCL

This looks good. The issue is really with BOINC that it refuses to report that I have an OpenCL supported device/driver.

Hi! This reminds me a bit

Hi!

This reminds me a bit about a problem we had at Albert, where (64 bit) BOINC client would "see" an OpenCL card, but the 32 bit app failed to see it.

The alleged solution was, somewhat surprisingly, that installing some X11 and other graphics related 32 bit compatibility libs fixed this, even tho they were not (directly) required by the app.

http://albert.phys.uwm.edu/forum_thread.php?id=8886&nowrap=true#112040

Just an idea.... maybe the OpenCL 32 bit runtime requires those.

Worth a try I'd guess.

EDIT: Gaurav, those other OpenCL applications that ARE working on your system, those are all 64 bit execs, right?

That looks all good indeed!

That looks all good indeed! Gaurav, please enable coproc_debug in your BOINC client configuration. You should see additional output in the BOINC client's event log after restarting it.

Gaurav, I'm terribly sorry

Gaurav, I'm terribly sorry that I missed this in your original message, but....did you upgrade your BOINC client to 7.0.27? I think that host is still on 7.0.26, and the minimum version for the ATI app on Einstein is (unlike at Albert) 7.0.27!

Unfortunately, the boinc.berkeley.edu server is currently down.
