[mvapich-discuss] Broadcast using infiniband's hardware multicast

[NARDI Luigi]

Hello,

I'm interested in using the MPI-level broadcast using infiniband's
hardware multicast functionality with MVAPICH2.

I have seen nice results in some papers of years 2005 and 2006.

May I know what is the implementation state of the art on this work?

I have seen that MVAPICH 0.9.9 User and Tuning Guide
(https://computing.llnl.gov/tutorials/linux_clusters/mvapich_user_guide_
099.pdf
<https://computing.llnl.gov/tutorials/linux_clusters/mvapich_user_guide_
099.pdf> ) in 2007 talks about this functionality 

but nothing is said about that on MVAPICH2 1.8 User Guide
(http://mvapich.cse.ohio-state.edu/support/mvapich2-1.8_alpha2_user_guid
e.pdf
<http://mvapich.cse.ohio-state.edu/support/mvapich2-1.8_alpha2_user_guid
e.pdf> ) in 2012.

Thanks in advance

Luigi Nardi
