Peregrine is the university compute cluster. The cluster has been delivered by Dell.

The peregrine falcon is the fastest animal on the planet. It can reach a speed of more than 320 km/h when stooping down on its prey.

The cluster can be used by scientists from the university. It is useful for solving computational problems for which a single PC is not powerful enough. For these problems the 4368 core Peregrine cluster can be used.

Specifications

Compute nodes

The cluster nodes come in three variants. There are 210 'standard' nodes with

  • 24 or 28 Intel Xeon 2.5 GHz cores
  • 128 GB internal memory

Furthermore 6 nodes with special accelerator cards are available. The other specifications are the same as above

  • 6 with 2 Nvidia K40 GPU cards

For jobs that need extra memory 7 nodes are available with

  • 48 Intel Xeon 2.6 GHz cores
  • 1024 or 2048 GB internal memory
Storage

Attached to the cluster is 463TB of disk space. Each node also has internal disk space of about 1 TB.

Network

The nodes are coupled using an 56 Gb/s Infiniband network. This network has both a high bandwidth (large amounts of data per second) and a low latency (minimal amount of time needed for sending small messages). This makes this network especially suited for tasks using more than one machine.

The system is also equipped with a 10 Gb/s Ethernet network, which is useful when accessing external data.

Parallel computing

The machines can be used to submit a large number of jobs. It is also possible to make use of the fast network between the nodes to submit a large parallel job. These jobs can run much faster than when running on a single core. In order to make use of this option programs often need to be adapted, for example by adding adding MPI calls. The CIT can assist you in making your program parallel.

Courses

The CIT also offers a beginners course for using the cluster. More information can be found on the course page.
