Questions & Answers

Q: What are the advantages of using parallel systems?

Parallel systems offer benefits such as improved computation time, reduced storage requirements, and the ability to perform multiple tasks simultaneously. They allow for faster processing and increased efficiency.

Q: How do speed-up and scale-up relate to parallel systems?

Speed-up refers to the reduction in response time achieved by parallel systems. It is calculated by comparing the time taken by a task in a single processor system (TL) to the time taken in a parallel system (TS). Scale-up, on the other hand, refers to increasing the number of tasks that can be performed within a certain time frame using multiple processors.

Q: What are the different types of interconnection networks in parallel systems?

There are several types of interconnection networks, including bus, mesh, and hypercube architectures. A bus architecture involves a backbone network connecting all computers, while a mesh architecture connects adjacent nodes. Hypercube networks follow a binary numbering scheme, connecting computers with one-bit differences.

Q: How does parallel database architecture work?

Parallel database architecture can be implemented using shared memory, shared disk, shared nothing, or hybrid approaches. Shared memory architecture involves multiple processors sharing a common memory, while shared disk architecture allows for sharing of disks. Shared nothing architecture ensures that each processor has its own memory and disk. Hybrid architecture combines elements of shared memory and shared nothing.
