Hello,
I've installed R on my RHEL3 cluster and I am trying to get Rmpi to
work properly.
R is installed using the following
./configure --prefix=/home/apps/R-2.2.0
I installed snow using
R CMD INSTALL /home/apps/snow
And finaly Rmpi
R CMD INSTALL /home/apps/Rmpi --configure-args=--with-mpi=/path/to/lam
There were no errors or warnings upon installation. However when i
perform the test below i get an error message
R> library(snow)
R> cl <- makeCluster(2)
Rmpi version: 0.4-9
Rmpi is an interface (wrapper) to MPI APIs
with interactive R slave functionalities.
See `library (help=Rmpi)' for details.
Error in dyn.load(x, as.logical(local), as.logical(now)) :
unable to load shared library
'/home/apps/R-2.2.0/lib/R/library/Rmpi/libs/Rmpi.so':
libmpi.so.0: cannot open shared object file: No such file or directory
Error in dyn.unload(x) : dynamic/shared library
'/home/apps/R-2.2.0/lib/R/library/Rmpi/libs/Rmpi.so' was not loaded
Error in makeMPIcluster(spec, ...) : the `Rmpi' package is needed for
MPI clusters.
The Rmpi.so exists and the permissions are fine. I also did a
lamboot, and its running in the backround fine as well. Any
suggestions?
Thanks.
not sure if this message sent the first time, sorry :)

Perhaps the issue is that you need to add a path to LD_LIBRARY_PATH so that the linker can find the mpi libs. HTH, + seth
