## CS 5802 - Introduction to Parallel Programming and Algorithms

Akl computer science or computer engineering. While computer architectures to deal with this were devised such as systolic arrays , few applications that fit this class materialized. Multiple-instruction-multiple-data MIMD programs are by far the most common type of parallel programs. According to David A. Patterson and John L. Hennessy , "Some machines are hybrids of these categories, of course, but this classic model has survived because it is simple, easy to understand, and gives a good first approximation.

It is also—perhaps because of its understandability—the most widely used scheme. Historically, 4-bit microprocessors were replaced with 8-bit, then bit, then bit microprocessors. This trend generally came to an end with the introduction of bit processors, which has been a standard in general-purpose computing for two decades.

Not until the early s, with the advent of x architectures, did bit processors become commonplace. Main article: Instruction-level parallelism A canonical processor without pipeline.

A canonical five-stage pipelined processor. A computer program is, in essence, a stream of instructions executed by a processor. These processors are known as subscalar processors. These instructions can be re-ordered and combined into groups which are then executed in parallel without changing the result of the program.

This is known as instruction-level parallelism. Advances in instruction-level parallelism dominated computer architecture from the mids until the mids. These processors are known as scalar processors. The Pentium 4 processor had a stage pipeline.

## An Introduction to Parallel Programming

Most modern processors also have multiple execution units. These processors are known as superscalar processors.

Instructions can be grouped together only if there is no data dependency between them. Scoreboarding and the Tomasulo algorithm which is similar to scoreboarding but makes use of register renaming are two of the most common techniques for implementing out-of-order execution and instruction-level parallelism.

Main article: Task parallelism Task parallelisms is the characteristic of a parallel program that "entirely different calculations can be performed on either the same or different sets of data". Task parallelism involves the decomposition of a task into sub-tasks and then allocating each sub-task to a processor for execution. The processors would then execute these sub-tasks concurrently and often cooperatively.

Task parallelism does not usually scale with the size of a problem. Distributed shared memory and memory virtualization combine the two approaches, where the processing element has its own local memory and access to the memory on non-local processors. Accesses to local memory are typically faster than accesses to non-local memory.These types of problems are often called embarrassingly parallel - little or no communications are required.
