The build is based on Rob Latham's MPICH-BlueGene fork (which is mostly mpich-3.1.4 plus BG/Q I/O work from mpich-3.2). This will give you, for example, an MPI_Fetch_and_op based on the underlying PAMI implementation.

If there are specific MPICH features you'd like in my branch, let me 
know and I will see how hard it is to backport.  I/O things are fairly 
easy to backport.  Anything that deals with the device layer will not be.

(the whole reason I'm stuck on summer 2015 is because device-level 
changes landed on master and the pami device has not yet been updated 
for those).
