Subject: Re: [Caml-list] OCamlMPI problem
Hi list!!!
After a hard work, I've eventually got testempi compiled. However, I'm
facing a new kind of problem now. When I just try to run testempi with
mpiexec tool, the 'mpd' process manager (that is, the default process
manager provided by MPICH2 implementation of MPI library) can not  work
properly. Instead,  I got an error message that says the 'lamd' daemon isn't
running. So, it asks me for starting 'lamboot'. So, I'm litte confused here:
is lamboot a tool from LAM/MPI Implementation, isn't it? Then, what about
MPICH2? I mean... do I need to use LAM/MPI to execute ocaml MPI application?
How can I get ocaml working good with MPICH2? 'cause I've already installed
and configured MPICH2 in my cluster.
By the way, does anybody know where to find a good tutorial about ocaml
MPI?? You know.. something with examples and so on!
Thanks in advance in sorry for my bad english!!
