[mpich-discuss] About the port

[Seo, Sangmin]

Hi Yi,

You can change ports MPICH uses by setting MPIR_CVAR_CH3_PORT_RANGE. Please refer to https://wiki.mpich.org/mpich/index.php/Frequently_Asked_Questions#Q:_How_do_I_control_which_ports_MPICH_uses.3F

Hi all,

I'm trying to compile a code under mingw with mpich-1.4.1p1, and I'm facing an error "No connection could be made because the target machine actively refused it".  (The target machine is my own PC and The firewall is closed)

After googled it I figured out may be it is the problem of the connecting port is different from the port which the PC is listening. I can check the listening port of mpich2_smpd is 0.0.0.0:8676<http://0.0.0.0:8676/>. but how can I find and change the connecting port?

Maybe it is a silly question.. I'm quite unfamiliar with the MPI.

Thank you.
