If you plan to use windows recommend mpich1 as this is what PETSc is usually tested with [as far as installation is concerned].
http://www-unix.mcs.anl.gov/mpi/mpich1/mpich-nt/ Configure will automatically look for it - and use it. The scalability depends upon the OS, MPI impl and MemoryBandwidh numbers for this hardware. Don't know enough about the OS & MPI part - but the MemoryBandwidh part is easy to check based on the hardware you have. [The new core duo chips appear to have high memory bandwidth numbers - so I think it should scale well] But you should be concerned about this only for performance measurents - but not during development. [You can install MPI on a single cpu machine and use PETSc on it - for development] Satish On Thu, 24 Aug 2006, Julian wrote: > Hello, > > So far, I have been using PETSc on a single processor windows machine.
