Ehh. Nobody does ia64 any more. It's dead, Jim.
This is x86. SGI finally long ago gave up on the Intel/HP clusterf*ck.
Which I'm not entirely sure makes the case for the kernel parameter much stronger, though. I wonder if it's not more appropriate to just have a total hack saying
if (max_pids < N * max_cpus) { printk("We have %d CPUs, increasing max_pids to %d\n"); max_pids = N*max_cpus; } where "N" is just some random fudge-factor. It's reasonable to expect a certain minimum number of processes per CPU, after all.
