[Rd] Rmpi on Linux (SuSE) with OpenMPI

[giuseppe1.milicia at hsbcib.com]

Guys,

I'm having troubles with Rmpi on Linux. I got it to work on windows, but on
Linux (SuSE 64 bit), using OpenMPI, I can't seem to get it to work :(

When I do library(Rmpi) I get the warning:

mca: base: component_find: unable to open osc pt2pt: file not found
(ignored)

Interestingly enough all the examples from the snow tutorial (
http://www.sfu.ca/~sblay/R/snow.html) work despite the warning.

But then, when I run my app I get

mca: base: component_find: unable to open osc pt2pt: file not found
(ignored)
mca: base: component_find: unable to open osc pt2pt: file not found
(ignored)
        2 slaves are spawned successfully. 0 failed.

Google has brought no useful info... The only discussion on the subject is
about an older version of Rmpi (I checked, the fix is in my version). For
reference that discussion is here
http://www.open-mpi.org/community/lists/users/2007/10/4185.php

I'm running on a multiple cpu box rather than a real cluster, that should
make things easier though... Perhaps some permission issue?

Cheers,

// Giuseppe
