 Peter's work list:
-1)- Half-precision comms                                <-- started -- SIMD is prepared
 2)- Precision conversion and sort out localConvert      <-- 
-
 3)- Remove DenseVector, DenseMatrix; Use Eigen instead. <-- started 
 4)- Binary I/O speed up & x-strips
-
 -- Profile CG, BlockCG, etc... Flop count/rate -- PARTIAL, time but no flop/s yet
 -- Physical propagator interface
 -- Conserved currents
 -- GaugeFix into central location
-
 -- Multigrid Wilson and DWF, compare to other Multigrid implementations
 -- HDCR resume
 
 Recent DONE 
+-- Cut down the exterior overhead                      <-- DONE
+-- Interior legs from SHM comms                        <-- DONE
+-- Half-precision comms                                <-- DONE
 -- Merge high precision reduction into develop        
 -- multiRHS DWF; benchmark on Cori/BNL for comms elimination
    -- slice* linalg routines for multiRHS, BlockCG
