<p class="MsoNormal">I am investigating the possibility of using MPI as an alternative to Winsock in our application.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Currently we have a thread to retrieve WinSock messages in a loop that uses the Windows function called WaitMessage.<o:p></o:p></p>
<p class="MsoNormal">This function suspends the current thread and does not return until a new message is placed in the thread’s message queue.<o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am looking for the equivalent function in MPI that allows me to get notified when a message arrive, but haven’t found anything so far.
<o:p></o:p></p>
<p class="MsoNormal">I found that there is MPI_Probe and MPI_Iprobe. It seems like both of these functions are doing polling instead of getting notification when there is message arrived, so it is taking up 100% of the CPU power even when it is just idling
to wait for message. <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I want to perform something like this:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">while (true)<o:p></o:p></p>
<p class="MsoNormal">{<o:p></o:p></p>
<p class="MsoNormal"> //wait for message without using CPU power<o:p></o:p></p>
<p class="MsoNormal"> //receive message and process it<o:p></o:p></p>
<p class="MsoNormal">}<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Is this possible in MPI?<o:p></o:p></p>
