1) Openmpi in PC1
I installed openmpi-1.4.3 using the OpenSuse 32b v. 12.1 repository
as well as openmpi devel
All mpi executables are present so are the libraries in lib directory.
I set the environment as ( .bashrc)
When I run any of the test examples (eg. mpirun hello_c.c or any program that has mpi interface included I get the message
mpirun was unable to launch the specified application as it could not find an executable:
while attempting to start process rank 0.
typing echo $LD_LIBRARY_PATH I should get something like /usr/lib/mpi/gcc/openmpi/lib. The only output I get is /usr/local/atlas3.10/lib (which is the blas/lapack library). Also Intel compilers library is not shown.
1) Openmpi installation in PC2
In OpenSuse v 12.1 64b I installed openmpi-1.4.3 downloading it from the openmpi site.
No error occured during ./configure, make, make install process.
The environment settings change a little but are very similar to those mentioned under PC1.
The same message as above is occuring.
in this case typing echo $LD_LIBRARY_PATH I get the correct output from the mpi library as /usr/local/lib64 and the executables are in /usr/local/bin.
Any help is wellcome
