You'll actually want to build with mpicxx as the compiler (or whatever
the appropriate mpi wrapper for your compiler is), not icc. Also, don't
select SMP unless (as noted in the charm++ docs and by the build script)
you want to run on a *single, SMP node*.

I've managed to successfully build NAMD on my local machine (not the cluster) using several different configurations (GCC, PGI, CUDA). However, I'm unclear as to how to proceed in the case of the cluster build. I'd like to use the Intel compilers as these give the best performance. I'd also like to use MPI.
