A Prioritized User Deadline Based and Cost Effective Resource Scheduling in
Grid Computing
Abstract: A Grid represents a decentralized interconnected parallel system with multiple heterogeneous
resources. Grid computing is a collection of computing resources that are collected from multiple
administrative domains to reach a common goal. By focusing on grid resource sharing and coordination,
managing capabilities, and attaining high efficiency, grid computing has become an important
component of the computer industry. Resource scheduling in computational grids has an important role
in improving the efficiency. The grid environment is very dynamic, with the number of resources, their
availability, CPU loads, and the amount of unused

A grid can be a collection of machines, sometimes referred to as nodes, resources,
members, donors, clients and hosts. They all contribute a combination of resources to the grid as a whole.
Some resources may be used by all users of the grid, while others may have some restrictions.
By focusing on grid resource sharing and coordination, managing capabilities, and attaining high
efficiency, grid computing has become an important component of the computer industry. However, it is
still in the developmental stage, and several issues and challenges remain to be addressed.
Of these issues and challenges, resource scheduling in computational grids has an important role
in improving the efficiency. The grid environment is very dynamic, with the number of resources, their
availability, CPU loads, and the amount of unused memory constantly changing. In addition, different
tasks have different characteristics that require different schedules. For instance, some tasks require high
processing speeds and may require a great deal of coordination between their processes. Finally, one of
the most important distinctive requirements of grid scheduling compared with other scheduling (such

It includes searching multiple administrative domains to
use a single machine or scheduling a single job for multiple resources use at a single site or multiple sites.
Grid scheduling is a software framework which collects resource state information and
requirements for execution of jobs, selects appropriate resources, predicts the potential performance for
each candidate schedule and determines the best schedule for the tasks to be executed on a resource,
subject to some performance goals [4].
Schedulers are also responsible for management of jobs such as allocating resources for jobs,
partitioning of jobs to perform parallel execution, data management, event correlation and service level
management capabilities. These schedulers can be arranged in a hierarchical structure with meta-
schedulers and local schedulers. The functions of the scheduler include: (1) collecting information of jobs
submitted to the grid system (2) collecting available resource information (3) computation of the mapping
of jobs to selected resources (4) allocation of jobs according to mapping and (5) monitoring the status of
job execution. The goal of scheduling is to achieve highest possible system throughput and to match
‘Chubby’ is a unified lock service created by Google to synchronize client activity with loosely coupled distributed systems. The principle objective of Chubby is to provide reliability and availability where as providing performance and storage capacity are considered to be optional goals. Before Chubby Google was using ad-hoc for elections, Chubby improved the availability of systems and reduced manual assistance at the time of failure. Chubby cells usually consist of chubby files, directories and servers, which are also known as replicas. These replicas to select the master use a consensus protocol.
In network computing, DCE (Distributed Computing Environment) is a software that is set up to manage data which is going into and out of
Not only will these innovations improve network strength, but possibly the speeds at which a client can access information from an application server. This has the potential to make cloud computing even more prevalent than it already is today because it would become easier to keep up with mass traffic to the servers. Large server banks would be able to be downsized slightly compared to their current sizes. The computer science techniques used in created Marple show that it is possible to even make an old process useful in modern applications. The hardware of Marple is also programmable making it extremely useful for any network engineers because they will be able to write custom software for Marple-based
HPC uses several parallel processing techniques to solve advanced computational problems quickly and reliably. HPC is widely used in sciatic computing applications like weather forecasting, molecular modeling, complex system simulations, etc. Traditional supercomputers are custom made and very expensive. A cluster, on the other hand, consists of loosely coupled of the-shelf components. Special programming techniques are required to exploit HPC capabilities.

Project Concept and Strategy a. Was the Woody 2000 project well-conceived? Give reasons for your opinion. Ans. When a project is to be conceived, it broadly needs its planners to: - Lay down the objectives of the objectives of the project - Lay down the strategies, to achieve the objectives - Communicate these objectives to the staff - Break down the strategies into work activities - Assign members who would work on each of the activities - Decide the activities that will need outsourcing, and account for them - Assign timelines to each of the activities - Assign performance indicators/measurables to each of the activities - Estimate the cost of each activity, and thus the cost of the total project - Take into account the contingencies - Lastly,
Plant-wide allocation method - method of allocating costs that uses one cost pool, and therefore one predetermined overhead rate, to allocate overhead costs. Departmental allocation method – is very similar to a plant-wide allocation method, however in this method one cost is allocated to a particular department. Activity-based costing (ABC) method was created in 1980s. It uses several cost pools, organized by activity, to allocate overhead costs in contrast to previously popular models of allocation of overhead, e.g. plant wide allocation uses one cost pool for the whole plant, and department allocation uses one cost pool for each department (K.Heisenberg, J.B.Hoyle, n.d.). Let’s have a look at five basic steps used in activity-based costing:
Each Client can submit jobs to one or multiple schedulers. Each scheduler after getting the output can push it back to the client that requested it. Individual workers are created on the virtual machine created by the
The user owns the server or pays to use the server. The server does what the user wants it to do, and nothing else. These servers offer the possibility to reconstruct technology, and industry. Although these PIMS are a security risk, they are far less risky than today’s large,
The process starts with reviewing the current operations, past experiences and subsequently identifying what needs to be improved. Secondly, planning needs envisioning the results that the project wants to achieve, and the steps or activities required to arrive at success, i.e. fulfilling the mission of the project. Scheduling is a tool to plan and monitor the progress of the project. The case study, “The Boeing 767: From Concept to Production”, gives an overview of the planning efforts and how the team managed and controlled schedules using various techniques.
