Thanks a lot for the link. Your benchmark is very well detailed and I
agree with you concerning MPI, Charmrun is the winner.
However, after having reproduced the build of charm and compiled Namd
again with g++ and smp, I still have the same problem that indicates
that it could be a hardware problem. Where did you find the +giga
+max_dgram_size options, I did not see it anywhere and what do they mean?
Thanks, Laurent
