How can I set number of processes in qtcreator in a c++ MPI program?
I add -n 4 into run arguments but the program was not run on 4 processes!!
Should I change CMakeLists?

1What happens when you try `mpiexec -n 4 yourprog` at the command line ? – High Performance Mark Aug 03 '15 at 11:00

@High Performance Mark, I have no problem in command line! I want to run the program from qt-creator – Ali Mirzaei Aug 03 '15 at 17:26

In qtcreator menu :
projects -> build & run -> run -> add custom executable:
Executable : mpiexec
Arguments : -n 4 main
Note: 4 is number of processes and main is your target name.

is there a variable I can use within qt creator for the target name, like %{targetName}? – Slava Aug 25 '16 at 15:55
