Questions and Issues While Using TRES Code

[lee0517-hub]

Dear TRES Developers,

First of all, I would like to express my sincere gratitude for your outstanding work on TRES, which is an incredibly powerful tool for triple star evolution.

I have been following the AMUSE documentation to set up the environment for TRES. Specifically, I installed AMUSE in development mode using pip install -e ., compiled the SEBA code with make seba.code, and then compiled TRES. Afterward, I tried running the simple example provided in your documentation, but encountered an error, as shown in below

I attempted to resolve the issue by setting the environment variable export RDMAV_FORK_SAFE=1, as suggested in the error message. However, the problem persisted, and I received another error,

To further investigate, I exited the AMUSE virtual environment and ran TRES.py without MPI. Surprisingly, the code executed successfully in this setup and just warning MPI not available. This leads me to suspect that there might be an issue with one of the compilation steps or with how MPI interacts with TRES within the AMUSE environment.

Additionally, I have a couple of questions regarding the output of TRES:

-- How can I determine if CHE has occurred in the inner binary from the output files?

-- Is there a more detailed tutorial or documentation available to help new users like me get started with TRES more quickly?

I would greatly appreciate any guidance or suggestions you can provide to resolve these issues and improve my understanding of TRES.

Thank you very much for your time and support.

Best regards,
Li Lei

Additionally, I attempted to enable the include_CHE option by editing the constants.C file in SeBa to ensure the case include_CHE returns true, then recompiled the code. Despite these changes, I still receive a terminal prompt indicating that include_CHE=True is required. Could there be another configuration or setting that needs adjustment to properly enable this feature?
