BlueGem is the BrisSynBio Supercomputer Cluster. It has over 900 Intel Haswell CPU cores, and 8 nVidia K80 GPUs. These are spread over 53 compute nodes and 4 GPU nodes, all connected together using a high-speed QDR Infiniband network, and attached to a high-performance and resilient Panasas network disk (60 TB).

Please read the pages below to get more information about how to use BlueGem.

• Disk space - information about how the disk is laid out, and where you should write your simulation data.
• Backups - information about backups on BlueGem (there are NO BACKUPS!).

BlueGem also runs its own webserver, on which you can get status information and see the jobs running on the queue. To access this webserver, use your browser to navigate to https://bluegem.acrc.bris.ac.uk. This link will only work from within the University firewall (i.e. on University computers), and you will need to log in using your BlueGem username and password. Please ignore any "invalid certificate" errors that your browser may report when you first connect to BlueGem.
