This means that the machines in your cluster do not have a shared file 
system, for example, they don't use NFS cross mounts to make a common file 
system visible (with the same path name) to each machine in your 
cluster.  The mpirun script relies on having a shared file system, though 
it is possible to run MPICH programs without one.  If you can't setup a 
shared file system, you will need to arrange to copy the executables to 
each machine first, and then use a "procgroup file" (covered in the 
documentation) to specify which executables to run on each machine.
