Programming Environment
The Lawrence HPC programming environment has the choice of two compilers: Intel and Gnu 4.8.5 (gcc).
Two options in Lawrence are available for OpenMP: OpenMP Intel and Gnu.
To choose a version of OpenMP, add the version number and "/intel" or "/gcc" to the module command.
# For the OpenMPI module with Gnu:
[[email protected]@login ~]$ module load openmpi-1.6/gcc
############## or ################
#For the OpenMPI module with OpenMP Intel:
[[email protected]@login ~]$ module load openmpi-1.6/intel
MPI's available with Lawrence: open MPI, mpich (ethernet), and mvapich (infinaband), intel impi
