QLogic MPI Details
Compile and run it as follows:
$ mpicxx -o hello hello++.cc
$ mpirun -np 10 -m mpihosts ./hello
Hello World! I am 9 of 10
Hello World! I am 2 of 10
Hello World! I am 4 of 10
Hello World! I am 1 of 10
Hello World! I am 7 of 10
Hello World! I am 6 of 10
Hello World! I am 3 of 10
Hello World! I am 0 of 10
Hello World! I am 5 of 10
Hello World! I am 8 of 10
Each of the scripts invokes the GNU compiler for the respective language and the
linker. See “To Use Another Compiler” on page 4-9 for an example of how to use
other compilers. The use of mpirun is the same for programs in all languages.
