Title
Description
Parallella is a single-board computer roughly the size of a credit card or Raspberry Pi. Parallella runs Linux. It has 18 cores (2 ARM, 16 RISC) and you can buy it online for about $150. This talk will explore two questions: (1) How parallel execution differs from serial, and (2) Why we care about parallelism. This talk is the sequel to Ray's Parallella talk from 2015.

The video titled *Get Ready for Parallel Programming, Featuring Parallela*, presented by Ray Hightower at the Ancient City Ruby 2016 event, introduces the Parallella single-board computer and emphasizes the importance of parallel programming in modern development. Key points include: - **Introduction to Parallella**: Parallella is a compact single-board computer, approximately the size of a credit card, equipped with 18 cores (2 ARM, 16 RISC), allowing for significant parallel processing capabilities. - **Significance of Parallelism**: The talk explores how parallelism differs from serial execution and why it is relevant for developers today, especially as Moore's Law approaches its limits, necessitating new methods for performance enhancement. - **Historical Context**: The concept of parallelism is grounded in earlier computing practices, illustrated by Admiral Grace Hopper's analogy about using multiple oxen to share a load instead of relying on a single powerful one. - **Concurrency vs. Parallelism**: A clear distinction is made between concurrency and parallelism. While concurrency allows multiple threads to progress, parallelism enables simultaneous execution of threads, which Hightower illustrates through programming examples. - **Energy Efficiency**: Parallella is highlighted for its low power consumption (5 watts) compared to traditional supercomputers, making it an attractive option for energy-conscious computing. - **Computer Architecture Insights**: The talk delves into the RISC and ARM architectures of Parallella, explaining their roles in efficient processing and potential scalability. - **Practical Demonstrations**: Hightower conducts performance comparisons, revealing that Parallella can attain competitive speeds in tasks like prime number calculations, performing on par with much more expensive MacBook Pro systems when utilizing its parallel processing capabilities. - **Applications of Parallelism**: Real-world applications like weather forecasting and finite element analysis are discussed to highlight how parallel processing can improve efficiency and accuracy in computations. Additionally, Hightower showcases a Ruby chat application that utilizes parallel computing features of Parallella. - **Field-Programmable Gate Array (FPGA) Functionality**: The FPGA capabilities of Parallella allow flexible and rapid reconfiguration for various tasks, enhancing its utility in different computing scenarios. - **Future of Parallel Computing**: Hightower mentions upcoming technologies like Pine64, a potential competitor to Parallella, and encourages exploration of parallel programming due to its innovative potential. In conclusion, the talk emphasizes that understanding and utilizing parallel programming is crucial for future development, given the limits of current computing advancements. Hightower invites the audience to ask questions and further explore this engaging topic.
