Exam 2: Performance Issues

The __________ Mean gives consistent results regardless of which system is used as a reference.

The use of multiple processors on the same chip is referred to as __________ and provides the potential to increase performance without increasing the clock rate.

The IAS is the prototype of all subsequent general-purpose computers.

_________ metric are required for all reported results and have strict guidelines for compilation.

__________ enables a processor to work simultaneously on multiple instructions by performing a different phase for each of the multiple instructions at the same time.

The desktop application(s)that require the great power of today's microprocessor-based systems include___________.

The cache holds recently accessed data.

The raw speed of the microprocessor will not achieve its potential unless it is fed a constant stream of work to do in the form of computer instructions.

Workstation systems cannot support highly sophisticated engineering and scientific applications.

A _________ suite is a collection of programs,defined in a high-level language,that together attempt to provide a representative test of a computer in a particular application or system programming area.

The interface between processor and ___________ is the most crucial pathway in the entire computer because it is responsible for carrying a constant flow of program instructions and data between memory chips and the processor.

A(n)__________ Mean is a good candidate for comparing the execution time performance of several systems.

__________ enables the processor to keep its execution engines as busy as possible by executing instructions that are likely to be needed.

Traditionally found on a plug-in graphics card,a _________ is used to encode and render 2D and 3D graphics as well as process video.

The three common formulas used for calculating a mean are arithmetic,harmonic,and __________ .

__________ law deals with the potential speedup of a program using multiple processors compared to a single processor.

A __________ is a core designed to perform parallel operations on graphics data.

With __________ the processor looks ahead in the instruction code fetched from memory and predicts which branches,or groups of instructions,are likely to be processed next.

Cloud service providers use massive high-performance banks of servers to satisfy high-volume,high-transaction-rate applications for a broad spectrum of clients.

A common measure of performance for a processor is the rate at which instructions are executed,expressed as millions of instructions per second (MIPS).
