Hello all Sorry about asking too many 101 level question, but here is another one:
I have a BTL layer code, called 'lf' that is ready for unit testing; it compiles with the OMPI tool chain (by doing a ./configure; make from the top level directory) and have the basic data transport calls implemented. How do I 'hook up' the BTL to the OMPI call chain? If I do the following: mpirin -np 2 --hostfile ~/hostfile -mca btl lf,self ./NPmpi it fails to run and the gist of the failure is that it does not even attempt connecting with the 'lf' BTL (the error says: 'BTLs attempted: self') The 'lf' NIC, and RDMA capable card, also has a TCP/IP interface and replacing 'lf' with 'tcp' in the above command *does* work. Thanks in advance Durga Life is complex. It has real and imaginary parts.
