I'm aware that goroutines are the way to deal with concurrency in Go, however I'm running a test in which I will be comparing a regular multithreaded server vs a server using level triggered epoll vs edge triggered epoll. I can figure out how to create the epoll ones, however I've searched hi and low on how to create threads manually to no avail.
You cannot do that. In Go you cannot control this kind of stuff.
You might be able to bind a goroutine to a CPU thread: http://play.golang.org/p/mNPCyvpN2R (run locally on a multi CPU/core machine).
