Compare the weaknesses of Shared-Disk (SD) and Shared-Nothing (SN) parallel architectures

Solutions

Expert Solution

Shared-Disk Architecture:
This type of architecture is used in distributed computing in which the nodes shared same disk and disk is accessible from all the cluster nodes. But each nodes also have their private memories and will be used in case of failure of shared disk.

Shared Nothing Parallel Architecture :
It is an architecture in which each node is independent and different nodes are interconnected by a network. Each node is made of a processor, main memory and disk. By using this network , the contention among nodes can be managed efficiently. In this architecture node do not share any memory. This architecture works effectively on high volume and read write operations.

Following are some difference in the form for table:

Shared Nothing Architecture	Shared Disk Architecture
Nodes do not share memory or storage.	Nodes share memory as well as the storage.
It is a cheaper hardware.	It is comparitively expensive hardware.
Data is parttioned.	Data is not partioned.
Load balancing is fixed.	Load balancing is dynamic.

A disk-shaped parallel plate capacitor is made with a radius of 2 cm and a plate separation distance of 2/π millimeters. The dielectric is in two layers, each of thickness 1/π mm. The first layer is all composed of a material with dielectric constant 9. The second layer is actually made of two materials in a bullseye pattern. The inner circle has radius 1 cm and dielectric constant 6. The annular ring around it has dielectric constant 4. The entire...
