Hi Hal,<div><br></div><div>As far as I can tell, there are only two distinct wrappers in the /home/projects/llvm/mpi/clang/bin folder, mpicc and mpicxx, and all of the others are simply symlinks to them. Is it possible that I am misunderstanding? </div>

What Jeff said is correct. Jeff, I did not specifically update the wrapper scripts after the V1R2 transition. Is there anything that I need to do for that?<br>
<br>
Also, Jack, are you using the mpic++ (with -std=c++11) wrapper or the mpic++11 wrapper?<br>
