Ok, unsubstantiated rumor time... I have heard that running AIX 3.1 (I think that's the right number) on an RS6000 530, there is an undocumented "feature." Namely, that there is a maximum number of processes that can be running simultaneously. I am NOT alking about maxuproc, which, by default, is 40. That only controls how many processes each user might run. I'm talking ALL processes, total! The way I hear it, if the unspecified max number is exceeded, the machine will start killing off the most resource hogging jobs, which in my case happen to belong to a research chemist who would be VERY upset if his calculations started dying. Is there a maximum nimber of total processes the 6000 can handle? If so, what is that number? And what happnes when you try to exceed it? -- Marc Cooper | "In my childhood, I WAS an imaginary playmate." marcc@ncsa.uiuc.edu | -Tom Robbins, EVEN GOWGIRLS GET THE BLUES National Center for Supercomputing Applications Disclaimer: "It's mine!

And what happnes when you try to exceed it? it is somewheres around 131,072. i've run about 1,200 or more processes on one at a time and it works just fine. a little slow ;-), but still just fine. -- John F.
