I'm trying to get the CULL helper processes to work on our 16-CPU Onyx (IR3, IRIX
6.5.20, Performer 3.0.1). However, it seems as if the processes are not started at all.
Here's a code fragment that shows what I've added to the C++-perfly source:

from perfly.C:

void
initConfig(void)
{
    int numCalli;
    if (ViewState->startCallig)
    {
        /* lets start the calligraphic boards if any */
        numCalli = StartCalligraphic(NumPipes);
        pfNotify(PFNFY_NOTICE, PFNFY_RESOURCE,
            "InitConfig() - found %d calligraphic board(s)", numCalli);
        if (numCalli)
            ViewState->calligBoard = 1;
        else
            ViewState->calligBoard = 0;
    }

    // our new additions:
    pfMultithread(0, PFPROC_CULL_SIDEKICK, 2); // pipenr, stage, nrofprocs
    pfMultithread(1, PFPROC_CULL_SIDEKICK, 2); // pipenr, stage, nrofprocs
    pfMultithread(2, PFPROC_CULL_SIDEKICK, 2); // pipenr, stage, nrofprocs
}

When I run it, I get the following messages:

PF Info(2): All 16 processors available on this machine.
PF Info: DBASE Process 207124 running on CPU 0.

PF -------------------------------------------

The 'pid=0' clearly indicates that something is wrong here...
By the way, the same thing happens when I run the 'standard' perfly.
Do I have to do something to explicitely 'enable' the forking of the sidekick processes?
Or is something else wrong?

Thanks for any help,
