 MVAPICH2 depends on the installation of the OFED Distribution stack with
 OpenSM running. The MPI module also requires an established network
-interface (either InfiniBand, IPoIB, iWARP, uDAPL, or Ethernet). BLCR
-support is needed if built with fault tolerance support. Similarly,

+ChangeLog
+---------
+
+* Features and Enhancements
+    - Significantly reduce memory footprint on some systems by changing
+      the stack size setting for multi-rail configurations
+    - Optimization to the number of RDMA Fast Path connections
+    - Performance improvements in Scatterv and Gatherv collectives for
+      CH3 interface (Thanks to Dan Kokran and Max Suarez of NASA for
+      identifying the issue)
+    - Tuning of Broadcast Collective
+    - Support for tuning of eager thresholds based on both adapter and
+      platform type
+    - Environment variables for message sizes can now be expressed in
+      short form K=Kilobytes and M=Megabytes (e.g.
+      MV2_IBA_EAGER_THRESHOLD=12K)
+    - Ability to selectively use some or all HCAs using colon separated
+      lists.  e.g. MV2_IBA_HCA=mlx4_0:mlx4_1
+    - Improved Bunch/Scatter mapping for process binding with HWLOC and
+      SMT support (Thanks to Dr. Bernd Kallies of ZIB for ideas and
+      suggestions)
+    - Update to Hydra code from MPICH2-1.3b1
+    - Auto-detection of various iWARP adapters
+    - Specifying MV2_USE_IWARP=1 is no longer needed when using iWARP
+    - Changing automatic eager threshold selection and tuning for iWARP
+      adapters based on number of nodes in the system instead of the
+      number of processes

+      Avneesh Pant of QLogic for the patch)
