to a remote host asynchronously. For example, the GUI program opens the connection via a button, but we do not want the GUI interface to freeze until the connection is complete. The Boost::asio provides an asynchronous way to connect.Use Bind shared_ptr.#include 　　If you want to pass a Boost::asio object, we generally use the SHARED_PTR smart pointer. Because most objects are non-copyable that cannot be copied, and we determine that the object remains valid for the duration of the call.We use b

My colleague implemented a Disney MPM Snow mock paper, and I ported it to Maya with the title of a material point method for snow simulationHere's the code: Https://github.com/league1991/MpmMayaThe plug-in leverages the OPENVDB library to output OPENVDB data, which can then be used to generate mesh rendering with OPENVDB. Using TBB for CPU parallelism, combined with C11 lambda expression, TBB programming is very convenient, basically do not need to ma

MPM multi-Process Processing moduleMPM is divided into three modes:1,preforkProcess model, each process processes a request, pattern: Parent Process —————— > multiple child Processes —————— > One child process processing a request2,workerThreading model, each process derives multiple threads, each thread processes a request, pattern: Parent Process —————— > multiple child processes —————— > Multiple threads are derived from each child process------->

Apache defaults to a thread-safe prefork,prefork MPM that uses multiple child processes, each of which has one thread, each processing only one request connection at a time, and one request fails to affect other requests, which is thread-safeWorkers use multi-process multithreading, each with multiple threads, each processing a request connection, with higher performance, but non-thread-safe.PHP's official recommendation does not use the thread of

Apache is based on modular design.The basic service also uses a modular design, but this module is exclusive and can only be called at the same time.The MPM (multi processing module) multi-processing module is a basic module. It was originally run on the Unix family of operating systems. Later, when porting to other platforms, a module based on the local operating system was selected.On the Unix family, the prefor, worker, and event three modules are
