OPENMP

Hi!

Open Multi-Processing is an application programming interface that supports multi-plataform shared memory multiprocessing programming in C,C++ and fortran on most processor architectures and operating systems, including Solaris, AIX,HP-UX, GNU/Linux, Mac OS X and windows plataforms. It consists of a set of compiler directives, library routines, and environment variables that influence run-time behavior.

 In this picture we can see a process using OPENMP. In this case all 4 CPUs work, but only one is the master CPU ..
