[Llvm-bgq-discuss] Details behind MPI wrapper for bgclang++

[Hal Finkel]

Jack,

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?

Also, Jack, are you using the mpic++ (with -std=c++11) wrapper or the mpic++11 wrapper?

 -Hal
