Is there any differences between send and dsend in SimGrid?

Question

除了阻塞/非阻塞功能外，SimGrid 中的 send 和 dsend 有什么区别吗？

Answer 1

dsend is a non-blocking detached send. If you look for a non-blocking send, then that's isend . The difference is that where you absolutely have to do MSG_comm_wait() or MSG_comm_test() to finish a communication that were started with isend (the data transfer will not occur unless you do so), you cannot interact with the communication started with dsend .

The concept of detached communications is inspired from detached threads, so it may help to read about it on the Internet.
