1 Raspberry Pi HPC Testbed By Bradford W. Bazemore Georgia Southern University

2 The Goal All in one cluster Energy efficient Cost effective Foundation for future work Multipurpose System

3 HPC Computing Centers  Mainframes  Supercomputers PC  Computing Centers to Computer Labs  HPC is still needed

4 Clusters Used in many fields  Engineering  Physics  Economics Complicated to design and build

5 MPI and Linux MPI the main tool for cluster programming Linux is the main OS of clusters Both inefficient Linux Kernel 15.9 million lines of code

6 Raspberry Pi Very small computer Cheap $$$ Energy Efficient Reusable 3D printed modular system

7 The Cluster Custom built 3D printed parts Modular Expandable Cost effective Energy efficient W

8 System Design Node i Node i+n Network Switch Power Supply Internet Main Power

9 Metrics Amdahl's Law

10 Conclusion VERY complex, VERY simple solution This is just the start Numerous applications
