  It has been designed,built and executed a code for the Fast Fourier Transform
(FFT),compiled and executed in a cluster of 2^n computers under the operating
system MacOS and using the routines MacMPI. As practical application,the code
has been used to obtain the transformed from an astronomic imagen,to execute a
filter on its and with a transformed inverse to recover the image with the
variates given by the filter.The computers arrangement are installed in the
Observatorio Astronomico National in Colombia under the name OAN Cluster and in
this has been executed several applications.
