I will be working on an 2,3 or 4 CPU Octane.
I want to do the normal app-cull-draw of Performer.
I would like to reserve one CPU for a numerical code
to be sproc'd by the Performer code before the main loop.
Basically...
/******************************
performer.c
******************************/
main() {
sproc(crunch, PR_SALL, (void *) &data);
set-up-performer()
while(!exitFlag) {
pfuGetMouse(&mouse);
pfiUpdateXformer(xformer);
pfFrame();
getmore();
}
}
void crunch(void *data){
sysmp (MP_MUSTRUN, (int) choose_cpu); /* <--------------- This alone */
crunch_some_numbers()
}
Basically,
I would like to ALWAYS use one CPU for a number crucher and NOTHING ELSE.
Sometimes, I will have 3 CPUS for the remaining Performer code.
Sometimes 1, or 2.
I will likely add the lines: pfMultiprocess( (int) atoi( argv[2] ));
or something to choose how many CPU's will run the viz part.
Regardless...
I want to ensure that the Octane's load balancing system
does not USE a designated CPU for anything else except what I say.
I understand that Performer will do internal sproc's, but I do not
want some sort of sproc collision?
Could someone advise me?
