Hello, I am having a problem with MPI4Py (version: mpiexec (OpenRTE) 4.1.5). I have been using it for months without a problem, however, out of no where, I am getting a bug where my program is only using Rank 0.
For example, when I run the command: mpiexec -n 5 python -m mpi4py.bench helloworld I get the following output: Hello, World! I am process 0 of 1 on Caitlins-MacBook-Air.local. Hello, World! I am process 0 of 1 on Caitlins-MacBook-Air.local. Hello, World! I am process 0 of 1 on Caitlins-MacBook-Air.local. Hello, World! I am process 0 of 1 on Caitlins-MacBook-Air.local. Hello, World! I am process 0 of 1 on Caitlins-MacBook-Air.local. I have not changed anything with my system. I was wondering if I can get some help on this issue? Thank you, Caitlin Lamirez
