Issue Encountered with Sniper Simulator in Fast-Forward / Cache-Only Mode

[Hee Woo Kim]

Dear whom may it concern,

I hope this email finds you well. My name is Heewoo Kim, and I am a Ph.D. student at the University of Michigan, Ann Arbor.

I am reaching out to you regarding an issue I've encountered while running a custom program written in C++ with the Sniper simulator. The program involves reading an external .txt file and performing computations. To focus solely on the computational aspect, I have set the Region of Interest (ROI) specifically for the computation, running the file reading part in fast-forward / cache-only mode.

However, I've encountered a problem where the Sniper simulator freezes when it encounters the file reading code during fast-forward / cache-only mode execution. Specifically, the simulator fails to advance to the next line when encountering functions like "getline();" or "inputfile >> contents >> ... ;". Strangely, running the entire program in detailed mode works perfectly fine.
Have you encountered similar issues before, or could you provide any guidance or advice on troubleshooting this matter?
I would greatly appreciate any assistance you can provide.

Thank you for your time and attention to this matter.

Best regards,
Heewoo Kim
