RUNFEKO: Abort(1614735) on node 0 (rank 0 in comm 0): Fatal error in PMPI_Init_thread

Ian_Hendricksen

Description: I am using Feko 2025 with a student license, and I am encountering an error when I enable parallel processing when running RUNFEKO. The complete log with debug logging enabled is attached below.

The error I am encountering appears related to this community post, where my error corresponding to the first side effect, but it is unclear how I update the fabrics drivers of the Intel MPI installation within my Feko installation.

Any help is appreciated! Please let me know if any further information is required. Below, I include the error log, the details of the product I am using, and details of my machine. Thank you!

Hi Ian,

Before I go to development with this, I would ask you to install Feko again. Maybe something went wrong?

Best regards,

Hi Ian,

1. Does the simulation run without "Parallel" eneabled?
   
   
2. Could you try with less parallel processes?
   
   

Best regards,
Torben

Hi Torben! Thanks for getting back to me.

I can run the simulations without "Parallel" enabled.

However, even if I reduce the number of cores to e.g., 2 or 4, I still receive the same error.

Best,

Ian

Hi Torben — a reinstallation did the trick. Uncertain where things went wrong in the initial installation, but I can now run simulations with "Parallel" enabled. Thanks!

Great, happy to hear! :) Have a nice weekend!
