I am running a granular frictionless short range repulsion simulation:
pair_style gran/hooke 1 0 1 0 0 0
pair_coeff * *
We have installed LAMMPS GPU on our CUDA cluster which is:GPU : Nvidia Tesla m2050 (1.15 GHz, 448) * 4EA
Each machine has 4 cores, so I need to use MPI to get the full machine:
# Set parallel environment (pe) to OpenMPI (opmi) and number of cores required.
#$ -pe gpu_openmpi 4
/home/program/lammps/lmp_gpu -sf gpu -pk gpu 1 -in in.file
Is this because pair_style gran/hooke apparently has no GPU speed up?
Or it is the installation problem on GPU?
I see in the net that people have already used GPU for granular simulations, but style hooke has no explicit GPU extension.
In advance, I appreciate your kind help!
