# this Makefile builds LAMMPS for openMPI running on Tbird
# as of April 09, you want these modules loaded, which are not the default:
#   mpi/openmpi-1.2.8_intel-11.0-f074-c074
#   misc/env-openmpi-1.2
#   compilers/intel-11.0-f074-c074
#   libraries/intel-mkl
#   libraries/intel_fftw-10.0.4.023
#   libraries/intel-mkl-11.0.074
# you can determine which modules are loaded by typing:
#   module list
# you can load these modules by putting
#   these lines in your .cshrc or other start-up shell file
#   or by typing them before you build LAMMPS:
#     module switch mpi mpi/openmpi-1.2.8_intel-11.0-f074-c074
#     module load libraries/intel_fftw-10.0.4.023
#     module load libraries/intel-mkl-11.0.074
# these same modules need to be loaded to submit a LAMMPS job,
#   either interactively or via a batch script
