Specifying the opencl_ati_101 plan class does not work. It's easy to see in sched_customize.cpp, line 580

This is the app_plan function:

 if (!strcmp(plan_class, "mt")) {
        return app_plan_mt(sreq, hu);
    } else if (strstr(plan_class, "ati")) {
        return app_plan_ati(sreq, plan_class, hu);
    } else if (strstr(plan_class, "cuda")) {
        return app_plan_cuda(sreq, plan_class, hu);
    } else if (!strcmp(plan_class, "nci")) {
        return app_plan_nci(sreq, hu);
    } else if (!strcmp(plan_class, "sse3")) {
        return app_plan_sse3(sreq, hu);
    } else if (!strcmp(plan_class, "vbox32")) {
        return app_plan_vbox(sreq, hu, false);
    } else if (!strcmp(plan_class, "vbox64")) {
        return app_plan_vbox(sreq, hu, true);
    } else if (strstr(plan_class, "opencl")) {
        return app_plan_opencl(sreq, plan_class, hu);
    }

In case of a plan class opencl_ati_101 the code returns app_plan_ati instead of traversing to app_plan_opencl, because of a substring comparison for ati.

The fix or rather workaround for this is easy: One just needs to make the opencl check before the ati one.

Thanks and bye!

When building an application with the current boinc api lib and running it live (that is with shared mem), the timer thread segfaults on Ubuntu 11.10.

The culprit is the timer thread, which dies after TIMER_PERIOD seconds are over (first time timer_handler is called). I think the problem is that the child thread exhausts its stacksize. I can attribute the crash to this changeset (25659): http://boinc.berkeley.edu/trac/changeset/25659/boinc/trunk/boinc/api/boinc_api.cpp

On Ubuntu MAXPATHLEN is 4096. Setting any of the fields changed in the changeset to MAXPATHLEN will produce a segfault. Even raising only abspath[1024] to abspath[3096] produces said segfault.

I'd like to increase the threads stacksize in valgrind, but you can only increase the main thread stacksize there, not the childs. This is one of the error messages: ==24957== Can't extend stack to 0x40273c0 during signal delivery for thread 2: ==24957== too small or bad protection modes

This is the test application, it inits and then sleeps forever and either segfaults or doesn't, depending on MAXPATHLEN.

#include <iostream>
#include <diagnostics.h>
#include <boinc_api.h>
int main(int argc, const char* argv [])
{
    boinc_init_diagnostics( BOINC_DIAG_TRACETOSTDERR|BOINC_DIAG_HEAPCHECKENABLED);
    int rc = boinc_init();
    for (unsigned int i = 0; i < 10000 ;)
    {
        sleep(3000);
    }
}

Any hints?

Thanks.
