 A CAF program is interpreted as if it was replicated a number of times and all copies were executed asynchronously.
 The number of copies is decided at execution time. Each copy (called *image*) has its own private variables.
-The variable syntax of Fortran language is extended with indexes in square brackets (called *co-dimension*), which represents a reference to data distributed across images.

 By default, the CAF is using Message Passing Interface (MPI) for lower-level communication, so there are some similarities with MPI.

 Because each image is running on its own, the image synchronization is needed to ensure, that all altered data are distributed to all images.
 Synchronization can be done across all images or only between selected images. Be aware, that selective synchronization can lead to the race condition problems like deadlock.
