Unlocking Linux Shared Memory: The Ultra-Fast Channel for Inter-Process Communication

Unlocking Linux Shared Memory: The Ultra-Fast Channel for Inter-Process Communication

1. Overview of Shared Memory Technology Shared Memory is one of the fastest inter-process communication (IPC) methods in Linux systems, allowing multiple processes to access the same physical memory area, thus avoiding the performance overhead of data copying between processes. Compared to other IPC mechanisms such as pipes and message queues, shared memory has the … Read more

Implementing Shared Memory in C: IPC Mechanism

Implementing Shared Memory in C: IPC Mechanism

Implementing Shared Memory in C: IPC Mechanism In operating systems, Inter-Process Communication (IPC) is a mechanism that allows different processes to exchange data. Shared memory is an important method of IPC that allows multiple processes to access the same physical memory. This method is fast and efficient, making it suitable for applications that require frequent … Read more

Choosing Between queue.Queue and torch.multiprocessing.Queue in Python Multithreading

Choosing Between queue.Queue and torch.multiprocessing.Queue in Python Multithreading

In a Python multithreading environment, one must choose between using the standard queue.Queue or torch.multiprocessing.Queue. I need to carefully analyze the differences between the two and their applicable scenarios, then provide recommendations based on the user’s specific needs. First, I need to recall the basic characteristics and design purposes of these two queues. queue.Queue is … Read more
