Is ring buffer same as circular buffer?
Ring Buffer (or Circular Buffer) is a bounded circular data structure that is used for buffering data between two or more threads. As we keep writing to a ring buffer, it wraps around as it reaches the end.
What happens when ring buffer is full?
If the buffer is full, we know that our capacity is at the maximum. If head is greater-than-or-equal-to the tail , we simply subtract the two values to get our size. If tail is greater than head , we need to offset the difference with max to get the correct size.
What is shared memory in Python multiprocessing?
shared_memory — Shared memory for direct access across processes. New in version 3.8. This module provides a class, SharedMemory , for the allocation and management of shared memory to be accessed by one or more processes on a multicore or symmetric multiprocessor (SMP) machine.
