A task is typically a program or program-like set of instructions that is executed by a processor. The matrix below defines the 4 possible classifications according to Flynn:Ī logically discrete section of computational work.Each of these dimensions can have only one of two possible states: Single or Multiple. Flynn's taxonomy distinguishes multi-processor computer architectures according to how they can be classified along the two independent dimensions of Instruction Stream and Data Stream.One of the more widely used classifications, in use since 1966, is called Flynn's Taxonomy.Examples are available in the references. There are a number of different ways to classify parallel computers.More info on his other remarkable accomplishments: Flynn's Classical Taxonomy The basic, fundamental architecture remains the same. Parallel computers still follow this basic design, just multiplied in units. Input/Output is the interface to the human operator.Arithmetic Unit performs basic arithmetic operations.Control unit fetches instructions/data from memory, decodes the instructions and then sequentially coordinates operations to accomplish the programmed task.Data is simply information to be used by the program.Program instructions are coded data which tell the computer to do something.Read/write, random access memory is used to store both program instructions and data.Only one instruction may execute at any moment in time.Instructions are executed sequentially one after another.

A problem is broken into a discrete series of instructions.

The tutorial concludes with several examples of how to parallelize several simple problems. These topics are followed by a series of practical discussions on a number of the complex issues related to designing and running parallel programs. The topics of parallel memory architectures and programming models are then explored. The tutorial begins with a discussion on parallel computing - what it is and how it's used, followed by a discussion on concepts and terminology associated with parallel computing. It is not intended to cover Parallel Programming in depth, as this would require significantly more time. As such, it covers just the very basics of parallel computing, and is intended for someone who is just becoming acquainted with the subject and who is planning to attend one or more of the other tutorials in this workshop. It is intended to provide only a brief overview of the extensive and broad topic of Parallel Computing, as a lead-in for the tutorials that follow it. This is the first tutorial in the "Livermore Computing Getting Started" workshop.
