hi all,
the questions were :
we'll install a 2100 with 2 cpus 5/250 640MO ram.
we're looking for information about multiporcessing with
DU 3.2c or 3.2d
1) is it possible to say to a process to work on one cpu ?
2) is it possible to say to a user to work on one cpu ?
3) is it possible to limit a user in the memory usage ?
the main work on this alpha, is computing.
the answers :
1) You need to look at the information to do with processor sets.
See the man entries you get with man -k processor as well as the
runon command
Yes : runon <CPU #>
(counting CPU # from 0 on, that is 0 or 1 in your case)
See related information:
psradm, pset_assign_cpu, pset_assign_pid, pset_create,
processor_sets
2) Yes : set up a "processor set" and runon -x enforce the processor
set for the process (see man runon)
3) If you use C-shell (csh) look at the limit memoryuse feature
(see man csh)
