MATLAB coder has been running for a week

I started running the MATLAB coder to convert a function to a MEX function a week ago. (At this point, it has been running 166 hours). It is on the first step - Automatically defining the input types.

The main input is a large data structure which is about 34 Gb. Running R2021b with 192 Gb of ram, and it seems to be using just over half of the available memory (102 Gb)

Does this seem reasonable that it should be running this long, or is it a sign that something is hung up?

It is highly unusual for MATLAB Coder to take this long in the type inference stage. This extended processing time is not normal and suggests that the process may be stuck. It is advisable to terminate the current process. Consider breaking down the task into smaller, more manageable parts if possible. Analyzing or converting smaller portions of the data or simplifying the data structure might help identify specific issues causing the delay.

Given the complexity of the issue, contacting MathWorks support directly could provide specific insights or solutions tailored to handling large data structures with MATLAB Coder.

Ensure the function and data structure are as optimized as possible before conversion. Simplifying the data structure or reducing its size, if feasible, might make the type inference process more manageable.
