Shared Memory Multiprocessor System Performance
Simulating Shared Memory Multiprocessor System Performance
In simulating the performance of shared-memory microprocessors, the study Shared-Memory Multiprocessor Systems -- Hierarchical Task Queue (Serrazi, 2007) seeks to isolate the effects of parallel processing as it relates to memory and process resource allocations. The researcher who also wrote this analysis relied on a series of very precise simulations of multiprocessor performance that sought to define variables to quantify the allocation of memory and processor performance in centralized, distributed, and highly hierarchically-driven memory and application load performance across a standardized memory usage architecture (Serrazi, 2007). The researcher concludes that of the three approaches to testing shared-memory multiprocessor systems, hierarchically-based methodologies are the most effective in optimizing shared memory performance as they compensate for shared memory performance. The author and researcher concludes from this analysis that the hierarchical model is the best for equally balancing workloads across tasks queues and seeking an optimal performance level. This imbalance of tasks queues could easily be averted through the more use of more efficiently algorithms, yet the researcher reverts to a more hierarchically-based approach to allocating processing across the...
New Payroll Application Architecture One of the most commonly automated business processes and operations in the recent past is payroll, which is also the most often used human resource solution. The increased use and automation of payroll is attributable to the need to ease and reduce the time spent in payroll processes, which is one of the first applications in the working environment. Despite the increased automation of payroll, there are
system development life cycle (SDLC) approach to the development of Information Systems and/or software is provided. An explanation of SDLC is offered, with different models applied in implementing SDLC delineated. Advantages and disadvantages associated with each of the models will be identified. System Development Life Cycle According to Walsham (1993), system development life cycle (SDLC) is an approach to developing an information system or software product that is characterized by a
Evolution of System Performance: RISC, pipelining, cache memory, virtual memory Historically, improvements in computer system performance have encompassed two distinct factors: improvements in speed and also improvements in the number of applications which can be run by the system. Of course, the two are interlinked given that high levels of speed are linked to expansions of short-term memory and the ability of computers to use that memory to perform critical functions. One
From approximately 1930 until the 1980s, rectangular and functional spaces were the chief form of architecture around the world in general. The latter part of the 20th century -- the 1980s onward -- saw change once again, however (2008). For the most part, 20th century architecture, however, "focused on machine aesthetics or functionality and failed to incorporate any ornamental accents in the structure" (2008). The designs were, for the

Indeed, the first use of the term 'architect' as against 'master mason' in France dates from 1511 and reflects the increasing influence of Italian ideas" ( P88). Heller goes on to state that "…humanist learning in architecture not only raised the status of the architect, it also helped to foster a new division of labor in construction…"( Heller 88). 1.4. Significance The innovative design that was exhibited in this construction was
