The Smallest Cluster in the World
2 likes1,208 views
The document discusses the GA144, the smallest computer cluster in the world. It is a single-chip system with 144 processing nodes, each with 20KB of memory, capable of 96 billion operations per second while consuming only 14-650 milliwatts of power. It provides parallel processing capabilities on a small scale and is being used for applications like cryptography, signal processing, and neural networks.
