§They run the same environment as the cluster

–RHEL6

–Bash, sbatch, and modules are preconfigured

§ It’s easier to work with large data sets

–Drag-and-Drop files in the GUI

–You don’t have to use an FTP client or the web interface

Modules

13

Modules are used to deploy multiple versions of different software tools.

See what modules are available

$ module avail

View loaded modules

$ module list

Load a module

$ module load <name>

Remove a module

$ module rm <name>

§You can install binaries in your home2 directory.

– For example: ./configure –prefix=/home2/username/folder

§You can not install RPM packages, but you can email [email protected] to request an installation.

Applications

14

Workstations and thin clients come with Bash and SBGrid preconfigured to test scripts before submitting them to the cluster.

§Run a script on a workstation with bash

§Check the Output Folder

Run a Job Locally

15

Submit a Job to the Cluster

16

§Run sbatch

§Check the queue with the squeue command

§Check the output folder

§Run a Graphical User Interface on a single HPC cluster node.$ remoteGUI

§Connect to the GUI session with the VNC client.

$ cat remoteGUI.txt

§Run a GUI session that utilizes one of the Nvidia GPUs. Requires SSH.

Downtime

Downtime for system upgrades will be announced two weeks in advance.

You will not be able to login to workstations or thin clients.

Incompatible Applications

OpenMPI, RDMA, GPU Direct will only work on the cluster

Connect to Nucleus with SSH to submit these jobs.

Power

Leave BioHPC systems powered on at all times, unless instructed otherwise.
