2018-09-12 · Semaphore Programming in Erlang and Elixir usually allows for no locking since the VM essentially handles it for you when communicating between processes. However, what about the situation when you have thousands of processes attempting to interact with a single resource such as a process?

Its value is positive or 0 and it can only be accessed through the two operations wait(s) and signal(s) , where s is an identifier representing the semaphore. •wait(s) decrements s if s > 0 ; if not, the process executing the operation wait(s) is suspended.

-export([wait/0, signal/0]). Semaphore Programming in Erlang and Elixir usually allows for no locking since the VM essentially handles it for you when communicating between processes. However, what about the situation when you have thousands of processes attempting to interact with a single resource such as a process? Semaphore.

The Erlang VM is built around coordinating through communication between processes, but we knew we didn’t want to overload a process responsible for doing this coordination. A semaphore can be emulated with a channel starting with n objects. Acquiring the semaphore is receiving an object from the channel Releasing the semaphore is sending by the object into the channel.
