For transferring data via Globus, you should use the endpoint <code>computecanada#beluga-dtn</code>, while for tools like rsync and scp you can use a login node. | For transferring data via Globus, you should use the endpoint <code>computecanada#beluga-dtn</code>, while for tools like rsync and scp you can use a login node. | ||

A Mellanox Infiniband EDR (100 Gb/s) network connects together all the nodes of the cluster. A central switch of 324 ports links the cluster's island topology with a maximum blocking factor of 5:1. The storage servers are networked with a non-blocking connection. The architecture permits multiple parallel jobs with up to 640 cores (or more) thanks to a non-blocking network. For jobs requiring greater parallelism, the blocking factor is 5:1 but even for jobs executed across several islands, the interconnection is high-performance. | A Mellanox Infiniband EDR (100 Gb/s) network connects together all the nodes of the cluster.
