When compiling for each architecture you should have -march equal to the lowest common denominator and -mcpu equal to the specific CPU you are compiling for. As most code will run on the machine that starts the process this will ensure the best overall performance. Jason -- [EMAIL PROTECTED] mailing list

You don't need to have the same optimization; you just need to be able to support the minimum hardware. eg: P1: -march=pentium -mcpu=pentium P4: -march=pentium -mcpu=pentium4 It won't give you as good a optimization as your regular -march=pentium4 but it will give you the best of both world.

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 + > Mikhail <[EMAIL PROTECTED]> wrote: > >On 07:45 Mon 20 Oct , Jeffrey Smelser wrote: > >>who the hell told you that??

RE: [gentoo-user] How can I setup a cluster?
You don't.. "I want to install openMosix but I am afraid my machines are too weak for this: A machine is never too weak: I have three P200s (64MB each) and two P166s (one with 48MB and one with 192MB). Two of them are on 10Base-T and the other three on 100Base-T. Even with these antiquated machines and "heterogenous" network, I get perfect load balancing to run simulation programs that I write in Perl. (See ProgramToTestACluster. Don't be held back by the fact your machines are old. To me this is a nice feature of openMosix: you can add newer machines to an existing cluster as they become available. And you do not need to have all identical machines. That's fantastic! However, a 100Base-T network is recommended! Contributed by Charles Nadeau. In fact: I had 6 486 computers (from 25 Mhz to 66 Mhz) sharing a Coax 10Mbit network. They all had 16MB of memory and no harddisk. That worked just fine. Processes migrated perfectly and everything was going as smooth as a baby's arse! :) Adding a P75 was no problem at all; simply editing openmosix.map and making sure all the kernels were the same version.

Re: [gentoo-user] How can I setup a cluster?
Yes, if you compile for an AMD and put it on a K6 I can see where it would break. But shouldn't it work if you compile each machine for itself - that is on the 486 you install Gentoo with 486 optimization, the AMD gets it's own optimization, etc. A cluster isn't much use if it has to have all identical hardware.

I'm openmosix user currently, and can comment that it works quite well in my setup. As far as I know, beowulf is no longer freely available. I do not know though how you are going to make non-linux (windows) machines to be part of your cluster (it is possible with MPI last I heard), unless you setup linux over there. Regarding file systems - I'm using NFS now (although you can use MFS (included with openmosix)), and it works quite well for me. Keep in mind (if you consider openmosix), that you will need to have the same optimizations on all nodes (e.g. software that compiled for AMD with athlon optimizations will not migrate on Celeron.
