This repo contains notes on building and programming a cluster comprised of multiple Raspberry Pi computers. It assumes relatively little prior knowledge, but does notably assume basic knowledge of the C programming language. Solutions to some exercises are provided.

The document is split into five sections:

1. Assembly of the Raspberry Pi cluster, including installing necessary software on each node. The section ends by running the xhpl benchmark on the cluster to determine its processing power.
2. Distributed C programming on the cluster using MPI (Message Passing Interface).
3. Parallel C programming using multiple cores of a single cluster node using OpenMP (Open Multi-Processing).
4. Hybrid parallel C programming using both MPI and OpenMP.
5. An additional section on CUDA programming, which can't be completed on the Raspberry Pi cluster.

Each section is precompiled in its own directory as main.pdf.
