DAPL providers ucm, scm are frequently mentioned, but what is libdaplomcm.so.2?

Could someone point me to a description of the use case for the DAPL provider libdaplomcm.so.2?

I am currently using the Intel MPI Library 4.1 for Linux with Mellanox OFED 2.1; shm:dapl and shm:ofa both seem to work, but with shm:dapl I get warning messages about not being able to find libdaplomcm.so.2. Mellanox DAPL does have this file. This file does not appear in DAPL 2.0.41 either: http://www.openfabrics.org/downloads/dapl/

I found the file in MPSS 3.2; can I just drop this file into a Mellanox 2.1 /usr/lib64 installation?

Typo: I meant "Mellanox DAPL does not have this file."

This provider is used for communication with an Intel® Xeon Phi™ Coprocessor and is installed as part of the Many Integrated Core (MIC) Platform Software Stack (MPSS).
