Here is the abstract:

Multicast is an important system-level one-to-many collective communication
service.  Several collective communication services such as broadcast and
scatter are a subset or a derivation of multicast.  Due to the importance 
of multicast, efficient implementation of multicast has been extensively
studied in the past.  Many studies use the ping-based benchmarking technique 
to evaluate the multicast performance.  However, this technique cannot 
measure the actual multicast latency and may mislead users.

This paper focuses on the benchmarking technique for multicast.
The proposed technique can provide an accurate measurement of the multicast
latency in a controlled environment without requiring a global clock and
without having to know the detailed implementation of the multicast algorithm. 
Experimental results conducted on the IBM/SP at Argonne National Laboratory
are presented. The technique can be extended to other one-to-all communications, 
such as scatter.
