Step 5 of 7: Compiling MPI Programs

Now that you are ready to compile a program, type "make <filename>" at a command tool prompt. The filename you type should be the excutable file name, not the source file name (ie. make example, instead of make example.c). This will cause Makefile to try to compile using the rules provided for that file. You will see lines appear on the screen, notifying you of what make is doing. Once you get the prompt back, and there are no errors in the program, you are ready to run the task.

Now that you have your executable files, you are ready to run them. Simply type the following line, substituting the proper arguments for the italicized words.

  • To start MPI, type the following on your screen. For first time type:-

% lamboost -v < hostfile >

           Subsequently, you will only need to type this after the above command:-   

% lamboost

  • To compile MPI programs, type:-

% mpicc -o file file.c                                           /* for C */                                            % mpiCC -o file file.cpp                                      /* for C++ */
