Ah so ... > sure beat the living daylights out of CPU0 Eh - not the kernels problem. If user level code, such a batch manager, screws up the configuration and leaves a bunch of orphans laying around, I'd just as soon cram them all into one corner. But this is likely reflecting a difference in our target markets. For my key customers, if a big job can't get exactly the resources it signed up for, that job might as well be taken out behind the barn and shot. One of the first features these customers demand is someway to guarantee that nothing else on the system will interfere with their key job(s). For such systems, misconfigured orphans should be quarantined so as to have the least impact on any remaining healthy jobs. I can well imagine that my customers needs are not universal. Whatever ... probably not worth worrying about. If the user level code doesn't like the kernel default here, then the user level code can just arrange it so that this line of code is almost never executed. > I think I was in a meeting when I sent that ...
