I run i-PI for some tutorials in tutorials/ folder by calling
"i-pi tutorial.xml" in one terminal and "i-pi-driver -m sg -h localhost -o 15 -p 31415" in another.
They seem to work: "tut.*" files are created.
However, I failed to run tutorials in lammps/ folder. I use Mar20 version of Lammps.
"lmp_mpi_serial -i in.lmp" command turned to the error message
