Unimplemented system call

Been trying to run certain benchmarks in multi2sim. Unfortunately all of these make unsupported system calls and the error says to report it as a bug in the project manager tools. I have no clue as to what that is referring to. It would be great if someone can point me to where i can request system calls. In any case the unsupported system call is getpriority.

Hello, I have the same problem. Did you solve that? Is there any way to avoid this error?
