Probably the best docs to check would be what were referred to in that thread, and http://www.open-mpi.org/papers/ppam-2005/ for an overview.
Read through ompi/mca/pml/pml.h. It's the interface for the MPI "engine" behind OMPI's point-to-point functions, like MPI_SEND and MPI_RECV and friends. The PML uses BTLs to perform all the transport-level operations (E.g., over a specific type of network and/or protocol). BTLs are dumb byte-pushers; they have no concept of MPI semantics -- all the MPI semantics are handled in the upper-level PML. BTLs are also not allowed to block; the PML will poll them when necessary. Look though ompi/mca/btl/btl.h for a description of the BTL interface that BTLs are expected to export. Also have a look at the following wiki pages: https://svn.open-mpi.org/trac/ompi/wiki/NewDeveloper https://svn.open-mpi.org/trac/ompi/wiki/UsingMercurial (same principles apply to git or any other DVCS) https://svn.open-mpi.org/trac/ompi/wiki/devel/Autogen https://svn.open-mpi.org/trac/ompi/wiki/devel/CreateComponent https://svn.open-mpi.org/trac/ompi/wiki/BTLSemantics On Jun 13, 2011, at 4:39 AM, Xin He I wrote: > Hi, > > I just started working on adding a BTL module of TIPC (Transparent > Inter-process Communication) for Open-mpi. > > My coworker post this topic a year ago : > http://www.open-mpi.org/community/lists/devel/2010/05/7914.php > > I read the thread.
