Issue #1

If you see an error like the one shown below and you did make the dummy MPI library in directory LAMMPSDIR/src/STUBS/ try to find a *.a file in there. There is a chance that it has a different name (libmpi_stubs.a for example). Renaming it to libmpi.a should fix the issue.

g++: ../STUBS/libmpi.a: No such file or directory
make[1]: *** [../lmp_serial] Error 1
make: *** [serial] Error 2

Issue #2

In the most recent LAMMPS update, the following warning was added, which comes up during AWSEM simulations.

WARNING: Communication cutoff XXX is shorter than a bond length based estimate of XXX. This may lead to errors. (../comm.cpp:696)

This does not affect AWSEM simulations and is the result of the short pair style cutoff that AWSEM currently uses.
