You can find the template for a BTL in ompi/mca/btl/template (You will find this on the subversion trunk). Copy and rename the folder/files. Use this as a starting point. For details on creating a new component (such as a new BTL) look here - https://svn.open-mpi.org/trac/ompi/wiki/devel/CreateComponent The following document might also be useful - http://www.open-mpi.org/papers/trinity-btl-2009/xenmpi_report.pdf
