well - that's how openmosix works. app. is being ran on another node. So I would say it is very close to if you run binary on another machine by copying it over there and executing. That's the problem with optimization - if you run binary on PI, [binary is] optimized for Athlon, - most likely it will not work over there. Yes, you can have mixed hardware on openmosix cluster - just use the same optimization on all nodes (e.g. march=i586, etc. So that you are sure all nodes will be able to run it). regards, > > On Mon, 20 Oct 2003 13:08:14 +0000 > Mikhail <[EMAIL PROTECTED]> wrote: > >On 07:45 Mon 20 Oct , Jeffrey Smelser wrote: > >>who the hell told you that??
