Can I use MPI_Probe to probe messsages sent by any collective operation?

In my code I have a server process repeatedly probing for incoming messages, which come in two types. One type of the two will be sent once by each process to give hint to the server process about its termination.

I was wondering if it is valid to use MPI_Broadcast to broadcast these termination messages and use MPI_Probe to probe their arrivals.

I tried using this combination but it failed. This failure might have been caused by some other things. So I would like anyone who knows about this to confirm.

Cheers.

Sometimes MPI is used to send low-entropy data in messages. So it can be useful to try to compress messages before sending it.
