Study Notes
SIMD Architectures
- SIMD (Single Instruction, Multiple Data) architectures exploit significant data-level parallelism, allowing simultaneous execution of operations on multiple data points.
- SIMD is known for being more energy efficient than MIMD (Multiple Instruction, Multiple Data) architectures.
Vector Processing
- The Father of Vector Processing and Supercomputing is widely recognized as William Kahan, who contributed greatly to the field.
- Vector processors operate on linear arrays of numbers known as 'vectors', performing computations on these sets of data.
- Vector processors are designed to carry out operations such as addition, subtraction, multiplication, and division across elements in a vector, enhancing the speed of mathematical calculations.
SIMD Variations
- Major variations of SIMD include vector architectures, SIMD extensions found in modern CPUs, and Graphics Processing Units (GPUs), which are optimized for handling multiple data streams in parallel.
- SIMD architectures enable programmers to adopt a sequential thinking style, which is particularly beneficial in applications for personal mobile devices, where power efficiency and performance are crucial.
Supercomputing
- Cray supercomputers are historically associated with advanced Vector Processing and Supercomputing applications, pushing the boundaries of computation during their time.
