Cluster Overview¶
The Dalek cluster is composed of two complementary families of compute nodes,
separated in two different racks, all managed by a single SLURM instance from
the frontend node front.dalek.
To connect to the cluster, refer to the SSH access page.
Dalek Topology¶
The following picture gives an overview of the Dalek cluster:
Dalek Rack — x86 / GPU¶
Four partitions of high-performance MoDT motherboards / mini-PCs equipped with consumer-grade CPUs and GPUs (Nvidia, AMD, Intel). Designed for rapid software prototyping and energy-efficiency measurements at scale.
