Fundamentals of Input and Output Performance

The I/O subsystem is a component of computer system design that uses buses to assist communication between the Central Processing Unit, Computer Memory/Storage, and Input and Output Devices (that is known as peripheral devices). The I/O subsystem includes disc controllers, tape drives, discs, system buses, and other devices. The I/O database application reads and writes drives using the operating system windows I/O.

Although most of your programming courses have focused on writing sequential programs, using lots of parallelism is the way to faster execution. We talked about two different basic execution models that can support massively-parallel execution: MIMD and SIMD. One of the easiest ways to get some speedup by parallel processing is to simultaneously execute multiple copies of the same sequential program with different input data. For example, if you need to convert thousands of images from color to black & white, simultaneously running 32 copies of a sequential program that converts a single image at a time could easily get you nearly 32X speedup over running one copy of the program at a time to process each image. Is that type of parallel execution essentially MIMD, SIMD, or equally suited to both MIMD and SIMD? Why?
Write an openMP program that calculates the integration of the following function F(x) = 2 x° - x? +2 x For the interval 0 to 5. Processor will be assigned equal parts of the interval to calculate its integration. Let the user enter the number of trapezoids for each interval. Time your execution for different number of processors (2-8). Report your findings.
Consider the two versions of Quicksort that are based on the following: (i) Median selection algorithm using the linear-time select method; (ii) The randomized pivot selection algorithm Which of the two algorithms has a faster worst-case asymptotic behavior? Which of the two algorithms has a faster average-case performance? Provide empirical evidence of your answer by writing the corresponding programs for each and conducting experimental evaluation. Your experimental results should provide evidence of your answer. For this you need to run an adequate number of experiments on a variety of array/list sizes (use large randomly generated lists of integers).
Instructions per second is a measure of a computer's processor speed. For complex instruction set computers, different instructions take different amounts of time, so the value measured depends on the instruction. Evaluate the statement below and show how to compile it by using an instruction set machine of three-address, two-address, and one- address. A*B Y = C+D
