Direct Access Transport Libraries - (latest release, 12/14/16, includes MIC support)
User space libraries/utilities for Direct Access Transport (DAT). DAT is a transport-independent, platform-independent Application Programming Interface that supports RDMA (remote direct memory access) devices. Directory includes packages that include libdat, libdapl, and utilities for DAT API Spec Version 2. NOTE: v1 is no longer supported and will not be included with OFED releases. MIC support has been added in dapl-2.1.0, see README.mcm for build and install details.
MIC support is provided with the new MCM provider and MPXYD service. MCM requires the Intel(R) MPSS 3.x (YOCTO) release for Linux to be installed on your system. MPSS 3.x for Linux can be downloaded from: http://software.intel.com/mic-developer
Highlights for 2.1.10 - CCL Proxy optimization for post_send, dtest/dtest_suite improvements, bug fixes, UCM log for timers
