I am a new user to OpenMPI and I am using java version of OpenMPI. I have
downloaded the nightly snapshot
your web page. unfortunately, there are not enough documentation on
your webpage for compiling and using java mpi programs. I have built
openmpi on /usr/local:
./configure --prefix=/usr/local --enable-mpi-java
make all install
export LD_LIBRARY_PATH to /usr/local/lib/openmpi/
now, I can compile a simple program easily by
mpijavac -d dd Hello.java
mpirun -np 2 java dd/Hello.class
but when I am trying to run it with mpirun I get the following error:
mpirun: error while loading shared libraries: libopen-rte.so.0: cannot open
shared object file: No such file or directory
Could you please give me some directions.
I am using Ubuntu Linux 11.10 and I am going to use openmpi later in Hadoop.
