Cluster Computing: A Deeper Dive

Understanding Cluster Computing

Cluster computing involves the interconnection of multiple computers, or nodes, to work collaboratively on tasks. This approach boosts computational power and enables the handling of tasks that would be too resource-intensive for a single machine. Raspberry Pi 3’s affordability makes it an excellent choice for building a cluster, especially for educational purposes or small-scale projects.

Setting Up a Raspberry Pi 3 Cluster

Setting up a cluster using Raspberry Pi 3 units might seem complex, but it’s an exciting endeavor. Here’s a simplified step-by-step guide:

  1. Gathering the Hardware: Collect the required number of Raspberry Pi 3 units, SD cards, power adapters, and a network switch.
  2. Preparing the SD Cards: Flash the Raspbian operating system onto the SD cards using a computer.
  3. Initial Configuration: Configure the network settings and ensure each Pi has a unique hostname.
  4. Enabling SSH: Activate Secure Shell (SSH) for remote access to the Pi units.
  5. Master and Slave Nodes: Designate one Pi as the master node and the rest as slave nodes.
  6. MPI Installation: Install a message-passing interface (MPI) library for efficient communication between nodes.
  7. Testing and Execution: Run test programs to ensure seamless communication between nodes, and then execute parallel programs.
