On how to run Gaussian on GPU nodes, see GitHub. G16 C.01 has the capability to run on those nodes using GPUs. Please note that if a template input file without the header lines containing " %RWF", and " %NoSave" directives, the script will prepend these lines to the input file based on variablesĮagle currently has 50 computing nodes with dual NVIDIA Tesla V100 GPUs and Gaussian Sets the directories for scratch files and environment variables needed by Gaussian The user scratch space is set to a directory in the user's scratch space, with a nameĬontaining the job ID so different jobs will not overwrite the disk space. The user also must supply the name of the input file ( INPUT_BASENAME). The g16_eagle python scriptĮdits the Default.Route file based on the SLURM environment set when the script is Need to have loaded the module before submitting the job. The gaussian module is loaded by the script automatically, so the user does not This script and sample Gaussian input are located at /nopt/nrel/apps/gaussian/examples. To submit a job with this script, one would type: sbatch g16.slurm # so clean these to make sure there is enough space. # on-node memory by other jobs that terminated incorrectly # Note: sometimes files may have been left behind in # Set required Gaussian environment variablesĮxport GAUSS_LFLAGS='-vv -opt ": ssh"'Įxport GAUSS_EXEDIR=$g16root/g16/linda-exe:$GAUSS_EXEDIR # Run gaussian Eagle script (performs much of the Gaussian setup) NUMRWFLINES=`grep "RWF" $INPUT_FILE | wc -l`Įcho "%RWF=$SCRATCH2/,$MEMSIZE,$SCRATCH/,-1" > infile # to the input file to be used in execution line # header not present, then script prepends these lines # are listed then file is used un-changed, if 3-line # Load Gaussian module to set environment An example script for batch submission is given below: Input file needs the following two directives to tell the program to put read-writeįiles first in /dev/shm (up to 5GB below), and to put data that exceeds 5GB into files in a directory on This scratch space is set automatically by the example script below.
Of scratch files into a local (on-node) in-memory filesystem called /dev/shm. To reduce this load, we recommend putting the first 5 GB or so When many Gaussian jobs are running, this can put a large traffic load on the Lustre Gaussian jobs typically write large amounts of information to temporary scratch files. Grid=Ultrafine," which means that individual SCF iterations will take longer withīatch Submission with Use of In-Memory Filesystem (Preferred Method) That's because Gaussian G16 has changed the default accuracy into "Int=Acc2E=12 Previous Gaussian 09 users sometimes may feel Gaussian 16 runs slower than GaussianĠ9.
