Testing instructions with MPICH on a network of workstations

For the sake of an example, we shall assume that you have installed the portable implementation of MPI, called MPICH, and built the PBLAS tester executables for each of the machines used in your application. The executable files are not required to be stored in a particular directory. Then, to run the executable, you will use the command mpirun. For example,

where $<$executable$>$ is replaced by xspblas1tst, and so on. If the network of workstations is heterogeneous, you will need to specify the -p4pg option and supply a text file containing the names of the machines and the locations of the executables to which you will spawn tasks. Refer to the mpirun manpage for complete details.
