You have to "configure --enable-debug" to get the debug information. You may want to pick up the latest dapl/test/dtest/dtest.c and take a look at the rdma write section for a simple multi-segment uDAPL example. I recently made a few modifications to include multiple segments in the test. You can also use dapltest to verify that RDMA with multple segments are working properly. Look at cl.sh for example script and "dapltest -TT --help" for usage. -arlin _______________________________________________ openib-general mailing list openib-general@openib.org http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
