MPI_THREAD_SINGLE程序中只有一个线程将执行。 MPI_THREAD_FUNNELED进程可能包含多个线程,但调用MPI_Init_thread的线程是唯一进行 MPI 函数调用的线程。 MPI_THREAD_SERIALIZED进程可能包含多个线程,所有这些线程都可以进行 MPI 函数调用,但一次只能调用一个。

Hello I have a application that uses MPI when calling MPI_INIT_THREAD i get an exception call MPI_INIT_THREAD( MPI_THREAD_FUNNELED, provided, ierr )
I am a developer using Intel MPI C++ Language with oneAPI version 2022.1, gcc 10.2.0.I met a wired problem that when I use MPI_Init_thread to init MPI program, I cannot brodcast large data between two nodes. The program hang long time but no output messsege. But u...

MPI_THREAD_SINGLE只有程式中的單一線程才會執行。 MPI_THREAD_FUNNELED進程可能包含多個執行緒,但呼叫MPI_Init_thread的執行緒是唯一進行 MPI 函式呼叫的執行緒。 MPI_THREAD_SERIALIZED進程可能包含多個執行緒,而且所有這些執行緒都可能會呼叫 MPI 函數,但一次只能呼叫一個。
MPI_THREAD_SINGLE 程序中只有一个线程将执行。 MPI_THREAD_FUNNELED 进程可能包含多个线程,但调用 MPI_Init_thread 的线程是唯一进行 MPI 函数调用的线程。 MPI_THREAD_SERIALIZED 进程可能包含多个线程,所有这些线程都可以进行 MPI 函数调用,但一次只能调用一个。 MPI_THREAD_MULTIPLE 多个应用程序线程可以毫无限制地...
So here's my question: can I continue building the application as I normally do then, say, on Windows, start multiple threads with _beginthreadex and, in each of the threads call MPI_Init_thread? In other words, would all subsequent calls to MPI behave as if I had a true ...
