Question

3. A) Explain the infrastructure requirements for grid computing.

B) What is the usage of Globus?

Answer 1

A Solution

Infrastructure requirements for grid Computing:

• Grid Computing:- It is the federation of computer resources from multiple administrative domains to reach a common goal.
• "Computational of the grid is a hardware and software infrastructure that provides independent pervasive and inexpensive access to high-end computational capabilities".
• Computational Grids are 1. Homogeneous (e.g., Clusters), 2. Heterogeneous (e.g., with one-of-a-kind instruments)
• Each user A network of geographically distributed resources including computers, peripherals, switches, instruments, and data.
• should have a single login account to access all resources. Resources may be owned by diverse organizations.
• Grid ware can be viewed as a special type of middleware that enables sharing and manage grid components based on user requirements and resource attributes (e.g., capacity, performance, availability…)

Methods of Grid Computing:

1. Distributed Supercomputing:- Combining multiple high-capacity resources on a computational grid into a single, virtual distributed supercomputer. Tackle problems that cannot be solved on a single system
2. High-Throughput Computing:-Uses the grid to schedule large numbers of loosely coupled or independent tasks, to put unused processor cycles to work
3. On-Demand Computing:- Uses grid capabilities to meet short-term requirements for resources that are not locally accessible. Models real-time computing demands.
4. Collaborative Computing:- Concerned primarily with enabling and enhancing human-to-human interactions. Applications are often structured in terms of a virtual shared space.
5. Logistical Networking:- Global scheduling and optimization of data movement. Contrasts with traditional networking, which does not explicitly model storage resources in the network are called Logistical

B Solution

Usage of Globus:-

• Globus is software with components and capabilities that includes: A set of service Implementations that Indicate resource management, data alterations service find, and relevant issue.
• Tools for building web services. Powerful standards-based security prerequisites for authentication and authorization.
• Various services in java,c, and python for clients of API and command-line programs.
• It is Architecture to give security to the software Application that likes information security and Resources
