Hi *,

How was MPI_Bcast() implemented on iPSC/860? I tested it with
NX's broadcast function and they performed the same.
So, I suspected MPI_Bcast() is simply a NX's broadcast function?
What's the time complexity of those two implementations?
Is it O(P) or O(logP)? P is the number of processors.

Thanks!
