Subject: [OMPI devel] MPI_Bcast using TIPC
From: Xin He (xin.i.he_at_[hidden])

Hi all,

sorry that it takes so long for paper works of TIPC BTL. Hopefully I can
get some feedback this week.

However, I would like to do some work while waiting. For future work, I
would like to add TIPC_broadcast
to support MPI_Bcast. But as I looked into TCP BTL code, I could not
find any code doing broadcast. Does
that mean MPI_Bcast is actually done by sending one by one? In that
case, in I want to add actual broadcast
support, which part should I change, I guess not just adding a BTL but
also modify PML as well?

Thank you in advance!
