Thank you about the answer to my Question. I will try this. but I believe, the compiler will include all the MPI's code, and I would like to disable this part with macros, because my programm works with lists and normally the list are made with pointers, and as far as I know, the MPI dont "like" pointers... So the Seriell version, when the MPI part is on, will not be optimized. With Regards Matheus

To run the serial version, you can call the binary directly and to run the parallel version run your program through mpirun to run inside the MPI enveronment. _______________________________________________ Beowulf mailing list, [email protected] To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
