Hi list!!!<br>After a hard work, I&#39;ve eventually got testempi compiled. However, I&#39;m facing a new kind of problem now. When I just try to run testempi with mpiexec tool, the &#39;mpd&#39; process manager (that is, the default process manager provided by MPICH2 implementation of MPI library) can not&nbsp; work properly. Instead,&nbsp; I got an error message that says the &#39;lamd&#39; daemon isn&#39;t running. So, it asks me for starting &#39;lamboot&#39;. So, I&#39;m litte confused here: is lamboot a tool from LAM/MPI Implementation, isn&#39;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? &#39;cause I&#39;ve already installed and configured MPICH2 in my cluster.
<br>By the way, does anybody know where to find a good tutorial about ocaml MPI?? You know.. something with examples and so on!<br>Thanks in advance in sorry for my bad english!!<br><br><div><span class="gmail_quote">2007/9/18, Andres Varon &lt;

That will take care of passing whatever flags are needed for proper compilation and linking. You can pass it to ocaml with:
