Run-Length Base-Delta Encoding for High-Speed Compression

Autor: Ettore Tiotto, Kit Barton, José Nelson Amaral, Taylor Lloyd

Publikováno v: ICPP Workshops

In modern supercomputers, nodes are connected by networking hardware capable of up to 40 Gb/s. Data compression could allow for even higher effective bandwidth. However, data compression for such systems requires a unique tradeoff between the compres

Programs written in Partitioned Global Address Space (PGAS) languages can access any location of the entire address space via standard read/write operations. However, the compiler have to create the communication mechanisms and the runtime system to
