Nikhef Grid Computing Cluster (NDPF)
Aim: Provide an overview of the Nikhef Grid Computing Cluster (NDPF).
Target audience: Users of the NDPF.
Introduction
The Grid computing cluster (commonly referred to as NDPF, or the Nikhef Data Processing Facility) is the distributed computing facility at Nikhef.
The NDPF is comprised of approximately 15000 CPU cores. All nodes are running a Debian 12 for its base operating system, however, all jobs run in a container either defined by the user (or collaboration's job submission script) or given the default container (Alma Linux 9).
Usage
Access and Use
The Grid cluster can be accessed from the interactive Stoomboot nodes, but submitting jobs to it is usually handled by a collaboration's Grid production system. As a user, you'll typically submit jobs to your collaboration's production system, which will then run some of them at Nikhef.
