Hi Dan, If you're interested in CPU affinity for the entire server process on Linux, you can use `taskset` https://linux.die.net/man/1/taskset. Otherwise, you'll likely want to patch `thd.cc` and use pthread's affinity APIs, but I don't recommend it.
For more advanced use cases with the C/C++ library, you can also get full control over the threading model and all async behavior by implementing a custom EventEngine <https://github.com/grpc/grpc/blob/5c988a47c4285bf8973a96c3a45bc15a7b9b678b/include/grpc/event_engine/event_engine.h> .
