Get Galaxy cluster

Warning

Currently, this feature is under beta testing. Galaxy and tools are installed on-the-fly starting from a bare CentOS 7 image. The whole process, i.e. install Galaxy and tools, may take time. We will soon add the possibility to exploit images with tools to speed-up the configuration.

It is possible to deploy a Galaxy cluster, using SLURM as Resource Manager, with or without automatic elasticity support.

1. Galaxy cluster section: all working nodes are deployed with the Galaxy server and are always available.
2. Galaxy elastic cluster serciont: automatic elasticity enables dynamic cluster resources scaling, deploying and powering on new working nodes depending on the workload of the cluster and powering-off them when no longer needed. This provides an efficient use of the resources, making them available only when really needed.

The two sections provide the same configuration options.

Warning

Each node takes 12 minutes or more to be instantiated. Therefore, the job needs the same time to start. On the contrary if the node is already deployed the job will start immediately.
