Introduction

Sample files are available illustrating the use of MPI calls to facilitate your getting started with MPI programming.

For an introduction to MPI, see: MPI Overview.

Hello World

Two very simple MPI programs which do more than display the text "Hello World!" from multiple processors, are listed in hello_world.php:

• Hello_World_C.c
  
  
• Hello_World_C.f90
  
  

Quadrature

QUADRATURE estimates an integral using quadrature and examples are available as:

• program.c, C program;
  
  
• program.cxx, C++ program; (an extension of ".C" or ".cpp" can also be used for C++ programs).
  
  
• program.f, FORTRAN77 program;
  
  
• program.f90, FORTRAN90 program;
