GAMESS

Description

GAMESS (General Atomic and Molecular Electronic Structure System) is a general purpose electronic structure code for computational chemistry. Its primary focus is on ab initio quantum chemistry calculations. The software can also do DFT calculations and other semi-empirical calculations (AM1, PM3), quantum mechanics/molecular mechanics (QM/MM) calculations, and can handle solvent effects. GAMESS has several fragmentation methods that can scale to as many as 260,000 cores, so users can apply GAMESS to very large molecular species.

Versions

Following versions of GAMESS are currently available:

  • Runtime dependencies:

You can load selected version (also with runtime dependencies) as a one module by following commands:

   module load GAMESS-US/2022-R2-intel-2022a

User guide

You can find the software documentation and user guide on the official GAMESS website.

Additional documents pertaining to GROMACS installation and running can be found here.

Benchmarks

In order to better understand how GAMESS utilises the available hardware on Devana and how to get good performance we can examine the effect on benchmark performance of the choice of the number of MPI ranks per node and OpenMP thread.

Following command has been used to run the benchmarks:

   rungms-dev $bechmark.inp 22 $processes $SLURM_NTASKS # Single node
   rungms-dev-02 $benchmark.inp 22 $processes $SLURM_JOB_NUM_NODES # Cross node
where processes represent pairs of compute processes & data servers, selected as half of requested MPI ranks.

For more information about these benchmarks systems see following page.

Info

"Single-node benchmarks have been run on local /work/ storage native to each compute node, which are generally faster than shared storage hosting /home/ and /scratch/ directories."

OpenMP

Current version of GAMESS-US is compiled without OpenMP support. Thus, the best performance can be achieved with maximum number of MPI ranks each running on single OMP thread, export OMP_NUM_THREADS=1. Following methods are threaded in OpenMP threaded version of GAMESS-US:

   * HF (see INTOMP in $INTGRL)
   * DFT (see BFCTYP in $DFT)
   * RI-MP2 (see CODE=OMPRIMP2 in $MP2)
   * RI-CC (see CCERI=RI in $CCINP)
Users can contact Devana support team via OSticket for compilation of OpenMP threaded version of GAMESS-US.

Example run script

You can copy and modify this script to gamess_run.sh and submit job to a compute node by command sbatch gamess_run.sh.

#!/bin/bash
#SBATCH -J "gamess_job"     # name of job in SLURM
#SBATCH --account=<project> # project number
#SBATCH --partition=        # selected partition (short, medium, long)
#SBATCH --ntasks=       # number of mpi ranks (parallel run)
#SBATCH --time=hh:mm:ss     # time limit for a job
#SBATCH -o stdout.%J.out    # standard output
#SBATCH -e stderr.%J.out    # error output

module load GAMESS-US
export OMP_NUM_THREADS=1

# -- USER MODIFICATION REQUIRED
export USERSCR=`pwd`  ### HOME folder, output
export SCRATCH=/work/$SLURM_JOB_ID ### Local scratch, default
# --------------------------------

input=
output=

processes=(echo "${SLURM_NTASKS} / 2" | bc)

# Start GAMESS-US
rungms-dev $input 22 $processes $SLURM_NTASKS > $output

Cross-node calculation

For GAMESS-US to run on multiple nodes following changes have to be made in the slurm submission script:

# Define ```SCRATCH``` and ```SCR``` environment variables to shared storage
export SCRATCH=/scratch/<project>/$SLURM_JOB_ID ### Local scratch, default
export SCR=/scratch/<project>/$SLURM_JOB_ID ### Local scratch, default

# Number of pair processes should be equal to number of nodes multipled by 32 (32 pairs per node)
processes=(echo "32 * ${SLURM_JOB_NUM_NODES}" | bc)

# Different script for starting calculation needs to be called and the second variable after version (22) is the number of nodes
rungms-dev-02 $input 22 $processes $SLURM_JOB_NUM_NODES > $output
