Question

Identify modern architectures and recent trends in computer architecture. (Hints: Parallel and Distributed Approaches, Pipelining, Multi-cores, etc.)

Describe about one in great detail.

Answer 1

VLSI era permits a big variety of additives to be accommodated on a unmarried chip and clock prices to increase. Therefore, greater operations may be accomplished at a time, in parallel.

Parallel processing is likewise related to information locality and information communication. Parallel Computer Architecture is the approach of organizing all of the sources to maximise the overall performance and the programmability withinside the limits given with the aid of using era and the value at any example of time.Parallel computer architecture uses  more and more number of processors. Performance achieved by utilizing large number of processors is higher than the performance of a single processor at a given point of time.

The conventional concepts of computer architecture is been enhanced with communication architecture by the paralle architecture. Computer architecture defines critical abstractions (like user-system boundary and hardware-software boundary) and organizational structure, whereas communication architecture defines the basic communication and synchronization operations. It also addresses the organizational structure.

With the advent of networks, distributed computing became feasible. A group of linked computers working cooperatively is known as distributed computing. Such computing usually requires a distributed operating system to manage the distributed resources. Important concerns are workload sharing, which attempts to take advantage of access to multiple computers to complete jobs faster; task migration, which supports workload sharing by efficiently distributing jobs among machines; and automatic task replication, which occurs at different sites for greater reliability.
