Open MPI will not run on PA-RISC processors. There are some functions in Open MPI that must be implemented in assembly. Presently, these are only supported for:

  * Alpha (32 or 64 bit, beta support)
  * IA-32
  * IA-64
  * MIPS (n32 or 64 bit APIs only, beta support)
  * Opteron / EM64T
  * PowerPC (32 or 64 bit)
  * UltraSparc (32 or 64 bit)
  * Windows (beta support)

Any other architectures are not supported and will not work.

I'm unaware of anyone ever testing on HP-UX.  So I don't know how
well it will do.

OMPI only has a few very-system-specific features, and there is a
pretty comprehensive "configure" script that may be able to figure
out all the HP-UX-isms, but I am guessing that there's going to be a
small number of "gotchas" along the way.

Hello,

I am planning to install OpenMPI on a HPUX system. Does anyone has
any experience using
OMPI on HPUX?

I do appreciate any comments.

Thanks

Nader,
