Software & Applications

IT is currently setting up a new platform for high-performance and high-throughput computing. The system will be composed of dedicated and general-purpose resources.

For more detailed information on computing resources please consult the official IT pages.

Search the compute space

The Maxwell-Cluster is composed of a core partition, partitions with specific capabilities like GPUs, and groups specific partitions. Currently the core partition is small, but will be extended over time. Partitions can and will overlap. The entire cluster will be managed with SLURM. The SLURM scheduler on the core partition will essentially work on a "who comes first" basis, but using a "back-fill algorithm" (smaller jobs filling the gaps without delaying other jobs will be executed prior to scheduled big jobs). The group specific partitions however have slightly different rules: though everyone can run jobs on group specific nodes, member of the group will have a higher priority and will compete non-group jobs off the partition. See Groups and Partitions on Maxwell for details.

Like the IT-HPC cluster, Maxwell is intended for parallel computation making best use of the multi-core architectures, the infiniband low-latency network, fast storage and available memory. The cluster is hence not suited for single-core computations or embarrassingly parallel jobs like Monte-Carlo productions. Use BIRD, Grid or your groups WGS for this kind of tasks. 

  • The Maxwell-Cluster is in many respects different from other resources. Please consult with the Using Maxwell page(s) for details. 
  • If you are familiar with the batch farm BIRD you might find the Slurm SLURM Rosetta table translating between different batch systems helpful. 
  • The Maxwell Hardware page provides a list of currently available nodes & configurations.
