How to use :
14
1- place a break point in the code where you need information
15
2- start the code with mpi, you get the pid of the process, attach gdb to the process (Xcode->Run->attach to process)
16
3- set the state variable to 1 (gdb command : set var state = 1)
17
18
Enjoy the graphic debuger, unfortunately only on one process in xcode, the second one must be controled
19
by hand using gdb/terminal
