Two machines.
A: 192.168.180.48
B: 192.168.60.203
The hostfile content is
192.168.60.203 slots=2
1. using openmpi 4.1.4, execute "mpirun -n 2 --machinefile hostfile
hostname" on machine A. The hostname of B is printed correctly.
2. However, using openmpi 5.0.0rc8, the result on machine A is
$m
mpirun --mca btl self,sm,tcp --mca btl_base_verbose 30 -np 2
--machinefile hostfile hostname
Why this sentence does not print IP addresses are routable in openmpi
5.0.0.rc9?
Hi, teachers
code:
import mpi4py
import time
import numpy as np
from mpi4py import MPI
comm = MPI.COMM_WORLD
rank = comm.Get_rank()
print("rank",rank)
if __name__ == '__main__':
if rank == 0:
mem = np.array([0], dtype='i')
win = MPI.Win.Create(mem, comm=comm)
else:
mpich users/help mail list.

*Subject: *[EXTERNAL] [OMPI users] OFI,
The execution of openmpi 5.0.0rc9 results in the following：
(py3.9) [user@machine01 share]$ mpirun -n 2 python test.py
[LOG_CAT_ML] component basesmuma is not available but requested in
hierarchy: basesmuma,basesmuma,ucx_p2p:basesmsocket,basesmuma,p2p
[LOG_CAT_ML] ml_discover_hierarchy exited
*Two machines, each with 64 cores. The contents of the hosts file are:*
192.168.180.48 slots=1
192.168.60.203 slots=1
*Why do you get the following error when running with openmpi 5.0.0rc9?*
(py3.9) [user@machine01 share]$ mpirun -n 2 --machinefile hosts hostname
