[Chimera-users] Need help for using Chimera

[Eric Pettersen]

Hi Lowie,
	On Linux using bash, type this in your shell window before starting Chimera (from that same shell window) to use 2 CPUs (obviously, use a higher number if you want to use more CPUs):

MMTK_ENERGY_THREADS=2
export MMTK_ENERGY_THREADS

	If you want to have MMTK in Chimera use multiple CPUs always, put those lines in your .bashrc and they will apply whenever you start a new shell.
