Not sure I understand your comment on multithreading. pthreads are not very hard to use, and you have stuff like OpenMP if you want some abstraction. What about C is not ideal for multithreading?

Thanks for the details! I have done MPI work in the past, so I was curious how an MPI implementation and iceoryx2 might be similar/different regarding local IPC transfers. It’d be interesting to do a detailed review of the two to see if they can benefit from each other.

Can you explain on a high level how iceoryx2 is able to achieve low latency? Is it as simple as using shared memory or are there other tricks in the background? Are there different transfer methods depending on the payload size?

Isn’t that how all physical media works?
