<DIV> </DIV>
<DIV>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. </DIV>

<DIV>With Regards</DIV>

P.ex.: myexe.exe -> runs in seriell, and when I write: myexe.exe -parallel -> runs in parallel.<BR>><BR>> I dont wanna compile ever when I need the program in seriel or in parallel. Usually is the seriell compilation with g++ and the parallel with mpiCC. Has anybody done a program like this before???<BR><BR>mpiCC is a wrap to g++ that adds flags to find MPI include and library files.<BR>You can compile both with mpiCC.<BR><BR>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.<BR></DIV><PRE>_______________________________________________
