And 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.
