Desmond
Description
From the Desmond web site: Desmond is a software package developed at D. E. Shaw Research to perform high-speed molecular dynamics simulations of biological systems on conventional commodity clusters, general-purpose supercomputers, and GPUs. The code uses novel parallel algorithms and numerical techniques to achieve high performance and accuracy on platforms containing a large number of processors, but may also be executed on a single computer.

Running Desmond on CIRCE
The Desmond user guide is essential to understanding the application and making the most of it. The guide and this page should help you to get started with your simulations. Please refer to the Documentation section for a link to the guide.
- Note on CIRCE: Make sure to run your jobs from your $WORK directory!
- Note: Scripts are provided as examples only. Your SLURM executables, tools, and options may vary from the example below. For help on submitting jobs to the queue, see our SLURM User’s Guide.
The user manuals related to Desmond are essential to understanding the application and making the most of it. The guides and this page should be all you need to get started with your simulations.

If, for example, you have a Desmond input file named example.cfg, you would set up a submit script like this:
- The script below (for testing, name it "desmond-test.sh") can be copied into your job directory (the folder with your input files) and modified so that you can submit batch processes to the queue. For help on submitting jobs to the queue, see our SLURM User's Guide. Scripts are provided as examples only. Your executables, tools, and options for SLURM will vary.
#!/bin/bash # #SBATCH --comment=desmond-example #SBATCH --ntasks=8 #SBATCH --job-name=dalton-test #SBATCH --output=output.%j.dalton-test #SBATCH --time=01:00:00 #### Slurm 8 processor Desmond test to run for 1 hour. module purge module load apps/desmond/2016.2 mpirun desmond --destrier mpi -tpp 1 --include example.cfg
- Then, you can change to your job's directory, and run the sbatch command to submit the job:
[user@login0 ~]$ cd my/job/directory [user@login0 jobdir]$ sbatch .desmond-test.sh/
- You can view the status of your job with the “squeue -u <username>” command
