Cisco Systems GEM318P Manual De Usuario

Select the language and compiler of your choice from the selection of compiler wrappers available in 

Compile the examples as shown here:

host1$ cd $HOME/mpi-examples 

host1$ mpicc.i -o hello_c hello_c.c 

host1$ mpiCC.i -o hello_cxx hello_cxx.cc 

host1$ mpif77.i -o hello_f77 hello_f77.f 

host1$ mpif90.i -o hello_f90 hello_f90.f90

The example above uses the Intel compiler. Change the command names as listed in 

 

if you are using the GNU or the PGI compiler.

If the $HOME/mpi-examples directory is not shared across all hosts in the cluster, copy the executables 
to a directory that is shared across all hosts, such as to a directory on a network file system.

Run the MPI program.

The following example shows how to run an MVAPICH MPI C program Hello World:

host1$ mpirun_rsh -np 2 -hostfile /tmp/hostfile $HOME/mpi-examples/hello_c

Hello, world, I am 0 of 2

Hello, world, I am 1 of 2
