GENESIS (GEneral NEural SImulation System) is a software platform for the simulation of neural systems ranging from subcellular components and biochemical reactions to complex models of single neurons, large networks, and systems-level processes.

Important Notes

Interactive job
Interactive jobs should be used for debugging, graphics, or applications that cannot be run as batch jobs.

Allocate an interactive session and run the program.
Sample session (user input in bold):

[user@biowulf]$ sinteractive
salloc.exe: Pending job allocation 46116226
salloc.exe: job 46116226 queued and waiting for resources
salloc.exe: job 46116226 has been allocated resources
salloc.exe: Granted job allocation 46116226
salloc.exe: Waiting for resource configuration
salloc.exe: Nodes cn3144 are ready for job

Batch job
Most jobs should be run as batch jobs.

To run Genesis as a batch job, you need to use nxgenesis rather than the default genesis which requires X11. Create a batch input file (e.g. For example:

set -e

module load genesis/2.4
nxgenesis myfile.g

Submit this job using the Slurm sbatch command.

sbatch [--mem=#]
