[英]Barrier implementation for inter process in shared memory
I am looking for an inter-processes barrier implementation. 我正在寻找进程间的屏障实现。 Processes are in shared memory (ie. on the same ndoe).
进程位于共享内存中(即,在同一主机上)。
Processes are MPI ones. 流程是MPI流程。 I do not want to use the MPI_Barrier function, because the general policy for all the MPI implementation is active waiting.
我不想使用MPI_Barrier函数,因为所有MPI实现的一般策略都是活动等待。 I want my processes sleeping as long as they wait.
我希望我的进程只要等待就可以休眠。
The restrictions: 限制条件:
I am confident it exists thousands of barrier implementation, but I do not find any?! 我相信它存在成千上万个障碍实施程序,但是我找不到任何?!
Thanks 谢谢
pthread_barrier
is the POSIX API for barriers. pthread_barrier
是用于屏障的POSIX API。 They may live in process shared memory if you initialize them accordingly. 如果您进行相应的初始化,它们可能会驻留在进程共享内存中。
You should check out Boost. 您应该查看Boost。 I believe that it has an interprocess module that you can use.
我相信它具有可以使用的进程间模块。
