Historical Background and Evolution of Parallel and Distributed Computing
Parallel and distributed computing have revolutionized the way we process vast amounts of data and execute complex computations. This tutorial provides a detailed overview of their historical background and evolution, tracing their development from early beginnings to modern advancements.
Early Foundations
- Parallel computing traces back to the 1940s with pioneers like Konrad Zuse and Alan Turing laying the groundwork.
- Advancements in the 1950s and 1960s led to systems like ILLIAC IV and CDC 6600, featuring multiple processors for parallel processing.
Emergence of Distributed Computing
- Distributed computing began in the 1960s with time-sharing systems allowing multiple users simultaneous access to a single computer.
- The ARPANET project in the late 1960s was pivotal, connecting remote computers and enabling distributed communication.
Supercomputing and Parallelism
- Supercomputers like Cray-1 and Cray-2 in the 1970s and 1980s employed parallel processing for high-performance computing.
- Parallel computing found applications in scientific fields like weather forecasting and computational fluid dynamics.
Rise of Cluster Computing
- Cluster computing emerged in the late 20th century as a cost-effective alternative to traditional supercomputers.
