+(including Xeon Phi).  It can be built in the following
+configurations:
+
+1. InfiniBand Open Fabrics, x86_64 (host), Linux
+
+   For this mode, configure with the following option:
+
+       --with-device=ch3:nemesis:dcfa
+
+2. InfiniBand Open Fabrics, Xeon Phi, Intel MPSS Linux
+
+   For this mode, configure with the following options:
+
+       --with-device=ch3:nemesis:dcfa
+       --with-cross=<mpich-source>/src/mpid/ch3/channels/nemesis/netmod/dcfa/cross_values.txt
