[OMPI users] Rmpi installation issues

2008-10-13 Thread Simone Giannerini
Dear all,

I have troubles installing rmpi  0.5-5 (or 0.5-6) on a quad opteron machine
with OpenSUSE 11.0 and
R 2.7.2

platform   x86_64-unknown-linux-gnu

system x86_64, linux-gnu

I tried the following

# export MPI_ROOT=/usr/lib64/mpi/gcc/openmpi/

# R CMD INSTALL  Rmpi_0.5-6.tar.gz

I also tried with

R CMD INSTALL  Rmpi_0.5-6.tar.gz
--configure-args=--with-mpi=/usr/lib64/mpi/gcc/openmpi/

with the same results.
Any help would be greatly appreciated.

Where did you get 0.5-6 from? The newest, per the author's website, is
0.5-5.

This seems to indicate that your installation of Open MPI conflicts with
your
setting of
export MPI_ROOT=/usr/lib64/mpi/gcc/openmpi/
as this directory is expected to contain include/ and lib/

I am not sure I got this,  Open MPI is installed in
/usr/lib64/mpi/gcc/openmpi/ and such directory contains both include and lib
folders:

Thank you, the following works for me:

# CC="mpicc"  R CMD INSTALL  Rmpi_0.5-5.tar.gz

# mpirun --version
mpirun (Open MPI) 1.2.5

So far so good, thanks also to *Sean Davis.*

Since I am not calling mpi directly but through Rmpi  I do not know where to
put that flag, I might contact the Rmpi mantainer, in any case, I would be
grateful if you had further suggestions.

Thank you very much,

thanks, I had also read some of  your previous posts but for sure I
should have tried harder.

I managed to upgrade to version 1.2.6 that has that option enabled by default.
Unfortunately though, it only suppresses the following warning

libibverbs: Fatal: couldn't read uverbs ABI version.

while the others remain.
In any case as I pointed out in my previous post the issue is that
only two threads are spawn per session.
Maybe I should try to check whether Ompi is working properly before
getting to Rmpi.
I will try to work it out,  of course any suggestions would be heartily welcome.

ciao

Simone
