NAMD 2.11 precompiled binaries do not work


NAMD 2.11 precompiled binaries do not work.  Please use NAMD 2.11 installed from the source and available via module namd/2.11.

The NAMD 2.11 issue involves changes to the command charmrun in Charmm++.

A typical symtom is:

Host key verification failed.

Charmrun> Error 255 returned from remote shell (n72:0)
