        The task seems to fail immediately, and the error message, "Could not create ..." makes it look very much like a 'permissions' problem.  Do you run BOINC as your normal user or was a special boinc:boinc user and group set up for the purpose?

        You should browse the complete BOINC directory structure looking for anything unusual in the ownership/permissions of all files and subdirectories.  During startup, slot directories are created/populated, one for each separate task that is running.  You might be able to find the particular slot directory for the last GPU task that crashed and examine all the remnants there to see if you can get any clues.  I've never felt the need to delve into the slot directories in detail (other than an occasional brief look) so I don't have any experience with which to guide you, unfortunately.  Maybe someone else with more knowledge about this might be able to chime in.

         

        Cheers,
        Gary.
