Problems Installing Rmpi on openSUSE 11.1 x86_64

Sorry. I forgot to say that Rmpi needs liblam.so as well. So use

	        MPI_LIBS="-L${MPI_ROOT}/lib64 -lmpi -lam"

Once compiled, use

         ldd path_to_Rmpi.so

to check if all libs are properly set. Again the following line in R  
script
LD_LIBRARY_PATH=/usr/local/lam/lib
is  useful in case ldd reports libmpi.so.0 or liblam.so.0 are not found.

Thanks to Hao, Brian and Martin (offlist) for their suggestions.

I tried them all:
- setting LD_LIBRARY_PATH
- using "--configure-args=--with-mpi=/path_to_lam"
- using mpicc
-> all without success when trying to install Rmpi (same error message  
as
before)

Since I cannot accept using OpenMPI using 100% CPU power in idle mode, I
still need to get LAM working.
Martin suggested modifiying "configure.ac":

   tar xzf Rmpi_0.5-7.tar.gz
   vim Rmpi/configure.ac

I added
after line 67:      MPITYPE="LAM"
after line 128:
	elif test -f ${MPI_ROOT}/lib64/libmpi.so; then #Till
	        echo "Found libmpi in ${MPI_ROOT}/lib64"
	        MPI_LIBS="-L${MPI_ROOT}/lib64 -lmpi"
		MPI_INCLUDE="${MPI_INCLUDE} ${MPI_INCLUDE}/64"

followed by
   cd Rmpi && autoconf && cd ..
   R CMD INSTALL --clean Rmpi

compiles without errors (see snippet 1 below).
However, when tryinig to load Rmpi in R I get an error:

library("Rmpi")

Error in dyn.load(file, DLLpath = DLLpath, ...) :
   kann shared library

wurde nicht geladen

Translation:

library("Rmpi")

Error in dyn.load(file, DLLpath = DLLpath, ...) :
   could not load shared library
'/home/francke/R/x86_64-unknown-linux-gnu-library/2.8/Rmpi/libs/Rmpi.so':

"Rmpi.so" exists, so I dunno what's wrong. Any help is appreciated,

Hi Melwin,

Did you try

R CMD INSTALL Rmpi_0.5-7.tar.gz  
--configure-args=--with-mpi=/path_to_lam

Your system may have several mpi and Rmpi did not find a right mpi.

BTW, when you are installing lam, make sure to turn dynamic lib on. The
default one is static one and Rmpi needs libmpi.so to work.

2009/6/24 Rowe, Brian Lee Yung (Portfolio Analytics) <B_Rowe at ml.com>:

Did you confirm that your MPI installation is working? That is the
probably the first step.

LAM seems to work ok:
? ?johnson at linuxmodel:~> lamboot -v

? ?LAM 7.1.4/MPI 2 C++/ROMIO - Indiana University

? ?n-1<4165> ssi:boot:base:linear: booting n0 (localhost)
? ?n-1<4165> ssi:boot:base:linear: finished
? ?johnson at linuxmodel:~> lamexec C hostname
? ?linuxmodel

Regarding LD_LIBRARY_PATH, since I don't know what your configuration
is, make sure you export it to your environment and also don't
overwrite
any existing values.
?i.e. This is better:
?$ export LD_LIBRARY_PATH=/usr/lib64:$LD_LIBRARY_PATH
since it looks like you're on a 64 bit platform.

Tried that. Same results as before:
? ?johnson at linuxmodel:~> ? ? R CMD INSTALL Rmpi_0.5-7.tar.gz

I use OpenMPI and it include an mpi-based compiler which I found to
work
better than gcc directly. You might try that. Just make sure you
export
your MPI_ROOT.

I would love to use OpenMPI, but I gather the slave spawning from
within R
is not yet possible - which is what I need in interactive mode
(https://stat.ethz.ch/pipermail/r-sig-hpc/2009-February/000104.html).
I'd
love to hear that this has changed.

It would also probably help to include a bit more output
from the compilation process.

The dump above contains the entire output, I hope that helps.

thanks again,
Melwin
