Hello Everybody,
I am trying to use SU2 with mpich as SU2's webpage suggests. When configuring I am using the command below: Code:
./meson.py build -Denable-autodiff=true -Denable-pywrapper=true -Denable-mpp=true -Dwith-mpi=enabled -Dcustom-mpi=true -Dextra-deps=mpich -prefix=home/directory Code:
export MPICC=/usr/bin/mpicc export MPICXX=/usr/bin/mpicxx export CC=$MPICC export CXX=$MPICXX Code:
Abort(70871301) on node 0: Fatal error in internal_Comm_rank: Invalid communicator, error stack: internal_Comm_rank(30212): MPI_Comm_rank(comm=0x2feb8c20, rank=0x5bff1f33fc48) failed internal_Comm_rank(30166): Invalid communicator The reason I am explaning this is I want to use Python Wrapper function so I can specify a custom inlet that comes with SU2v8.1. When I use regular cc and c++ for installation and do Code:
import sys import pysu2 import math from mpi4py import MPI def main(): """ Run the flow solver with a custom inlet (function of time and space). """ comm = MPI.COMM_WORLD # comm = 0 . . . Code:
Attempting to use an MPI routine (internal_Comm_rank) before initializing or after finalizing MPICH Last edited by CleverBoy; October 21, 2024 at 17:19. |
