dual processing

Hi all,

I have a dual processor linux machine. Is there a way to use each processor individually? For example, have one job sent to processor 1 and a second job (completely independent of job 1) sent to processor 2?

Thanks,

Jon

No need to worry about a thing, if you have compiled the kernel with SMP support, it will do this fully automatically to get the most out of both processors.

Im running a Dual too, and to my knowledge there -was- a patch for kernel-2.2x's called Pset for setting processor affinity like NT4/NT5 knows. Now only the cached page remains. The utils Ive found, the patch not.
Kernel-2.4x has better chances look at http://www.uow.edu.au/~andrewm/ and http://people.redhat.com/mingo/.

Are you doing this for programming environment purposes or just wanna execute stuff on seperate CPU for no important reason!...Coz there this Lam-mpi C, fortran and romio environment which will allow you to run stuff and send to certain CPU.. for example " #mpirun ./run.c n0 & " will execute program run.c on CPU #1 and so forth.....
