Little new: installing the new ATI driver, boinc is running with CPU computation after the GPU is not recognized (without the crash; the crash instead is still present using boinc 6.10.17), so the proposed fix is working.

I obtain this now (using the given fix in source):

The code did not crash, but computation did not goes with CPU (however this could be given by the fact that I run boinc from compiled code without proper installation).
By the way I'm migrating to Fedora 12 and I'm being installed the new ATI driver just released: I hope to have GPU computation working with those updates

In my system, the Segmentation fault appears in this point of coproc.cpp:

retval = (*__calInit)();


calInit is given by:

callib = dlopen("libaticalrt.so", RTLD_NOW);


These are the dependencies of the library:

[root@localhost ice]# ldd /usr/lib64/libaticalrt.so

However the error is generated into libaticaldd.so that seems not directly related to libaticalrt.so from the dependencies.

I test this with the latest trunk version (8.11.0) and with ElecticFence active for catching the segmentation fault point.

Post:

There is no algorithm; BOINC checks which driver files are available (in the system path) of your system. Minimum required for 6.10 is Catalysts 8.12


Maybe the problem is in ATI driver calling as in coproc.ccp get method, because no one of that print message are printed.

I will try to compile BOINC from the source this night and then go into debug to see the point where there is the segmentation fault..

Post:
No hardware is build to last forever, while these early GPUs are not build to run calculations 24/7 without letup.

I did not use the GPU for computation before (it is a HD2600xt) and I just test the BOINC cliant after the computer was turned off for more that 12h.
So far the ATI control center did not found errors into the card, so I hope it is fine.

I use Fedora Core 8 for all day works (and here BOINC 6.10.17 runs as ATI driver is old: 8.6 or something and so GPU is not detected), but I wont to migrate to Fedora 11 as soon as I have BOIN run with GPU.

Have you also posted this at Collatz? It could be a problem with their application, although I don't think it is.

I think even that did not depend by Collatz, but from the GPU dectection algorithm.

However it could be better if in the future the BOINC client will have a command line switch that disable GPU detection, so the program can run using only the CPU.
I did not find actually a way to disable GPU detection.

From when I install official latest ATI driver 9.10 for a X86_64, BOINC did not run anymore (due a segfault in testing GPU):

Exiting...


Unfortunately I cannot do more, as even BOINC and ATI driver as at latest version available.
Any idea for helping in this?

I use Fedora Core 11 with 2.6.29.4-167.fc11.x86_64 kernel (with kernel 2.6.30 I lost 3D application onto ATI driver)
