About using dynamic load balancing (fix balance) in LIGGHTS-benchmark

Hi, All:

I was trying to use the dynamic load balancing of LIGGHTS to minimize the computational time. I found the following document: http://cfdem.dcs-computing.com/media/DEM/benchmarks/LIGGGHTS_Benchmarks.pdf, the LIGGGHTS version I am using is: Version LIGGGHTS-PUBLIC 3.0.6

However if I try to use the load balancing command (e.g. in page 43 of the document) :

fix lb all balance 0 xyz 10 1.1 out balance.txt

The program prompts the error:

fix lb all balance 0 xyz 10 1.1 out balance.txt
ERROR: Invalid fix style: "balance" (../modify.cpp:789)

Is there any LIGGGHTS/LAMMPS package that needs to be installed during compiling like make yes-molecule?

Thanks a lot!
