Q1: A : yes, the gcc 4.8.2 stuff works with totalview

I use the bgclang wrapper for C compilation and bgclang++ or bgclang++11 for C++, but I do not use the bgclang MPI wrappers and I setup the MPI include and link paths/flags/libs myself using a bunch of cmake settings. The mpi used on the ION is an mvapich installed as part of the default system. (I do have trouble with performance of mpi programs, so am open to further experimentation there).

$echo $CC
/gpfs/bbp.cscs.ch/home/biddisco/apps/clang/bgclang/bin/bgclang

$ echo $CXX
/gpfs/bbp.cscs.ch/home/biddisco/apps/clang/bgclang/bin/bgclang++11

the full verbose link command would expand out to this ....
(NB, all the stuff which is in /gpfs/bbp.cscs.ch/home/biddisco/apps/clang like the log4cxx and boost libs is/are compiled by me using the same basic setup).
