This document proposes a fair scheduling algorithm with dynamic load balancing for grid computing. It begins by introducing grid computing and the need for efficient load balancing algorithms to distribute tasks. It then describes dynamic load balancing approaches, including information, triggering, resource type, location, and selection policies. The proposed algorithm uses a fair scheduling approach that assigns tasks to processors based on their estimated fair completion times to ensure tasks receive equal shares of computing resources. It also includes a dynamic load balancing component that migrates tasks between processors to maintain balanced loads across all resources. Simulation results demonstrated the algorithm achieved balanced loads across processors and reduced overall task completion times.
This document proposes a new task scheduling algorithm called Dynamic Heterogeneous Shortest Job First (DHSJF) for heterogeneous cloud computing systems. DHSJF aims to improve performance metrics like reduced makespan and low energy consumption by considering the heterogeneity of resources and workloads. It discusses existing scheduling algorithms like Round Robin, First Come First Serve and their limitations. The proposed DHSJF algorithm prioritizes tasks with the shortest estimated completion time to optimize resource utilization and improve overall performance of the cloud computing system. Simulation results show that DHSJF provides better results for metrics like average waiting time and turnaround time as compared to Round Robin and First Come First Serve scheduling algorithms.
Modified Active Monitoring Load Balancing with Cloud Computingijsrd.com
Cloud computing is internet-based computing in which large groups of remote servers are networked to allow the centralized data storage, and online access to computer services or resources. Load Balancing is essential for efficient operations in distributed environments. As Cloud Computing is growing rapidly and clients are demanding more services and better results, load balancing for the Cloud has become a very interesting and important research area. In the absence of proper load balancing strategy/technique the growth of CC will never go as per predictions. The main focus of this paper is to verify the approach that has been proposed in the model paper [3]. An efficient load balancing algorithm has the ability to reduce the data center processing time, overall response time and to cope with the dynamic changes of cloud computing environments. The traditional load balancing Active Monitoring algorithm has been modified to achieve better data center processing time and overall response time. The algorithm presented in this paper efficiently distributes the requests to all the VMs for their execution, considering the CPU utilization of all VMs.

LOAD BALANCING ALGORITHM TO IMPROVE RESPONSE TIME ON CLOUD COMPUTINGijccsa
Load balancing techniques in cloud computing can be applied at different levels. There are two main
levels: load balancing on physical server and load balancing on virtual servers. Load balancing on a
physical server is policy of allocating physical servers to virtual machines. And load balancing on virtual
machines is a policy of allocating resources from physical server to virtual machines for tasks or
applications running on them. Depending on the requests of the user on cloud computing is SaaS (Software
as a Service), PaaS (Platform as a Service) or IaaS (Infrastructure as a Service) that has a proper load
balancing policy. When receiving the task, the cloud data center will have to allocate these tasks efficiently
so that the response time is minimized to avoid congestion. Load balancing should also be performed
between different datacenters in the cloud to ensure minimum transfer time. In this paper, we propose a
virtual machine-level load balancing algorithm that aims to improve the average response time and
average processing time of the system in the cloud environment. The proposed algorithm is compared to the
algorithms of Avoid Deadlocks [5], Maxmin [6], Throttled [8] and the results show that our algorithms
have optimized response times.

Enhanced equally distributed load balancing algorithm for cloud computingeSAT Journals
Abstract Cloud Computing as the name suggests, it is a style of computing where different users uses the resources on the go i.e. over the Internet. In the recent era, this technology has emerged as a strong option for not only large scale organizations but also for small scale organizations that only access/use the resources what they want. In recent research study, many organizations lose significant part of their revenues in handling the requests given by the clients over the web servers i.e. unable to balance the load for web servers which results in loss of data, delay in time and increased costs. This Paper gives a new enhanced load balancing algorithm by which the performance of their web application can be increased. This Algorithm works on the major drawbacks such as delay in time, response to request ratio etc.
This document discusses load balancing in distributed systems. It provides definitions of static and dynamic load balancing, compares their approaches, and describes several dynamic load balancing algorithms. Static load balancing assigns tasks at compile time without migration, while dynamic approaches migrate tasks at runtime based on current system state. Dynamic approaches have overhead from migration but better utilize resources. Specific dynamic algorithms discussed include nearest neighbor, random, adaptive contracting with neighbor, and centralized information approaches.
A survey of various scheduling algorithm in cloud computing environmenteSAT Journals
Abstract Cloud computing is known as a provider of dynamic services using very large scalable and virtualized resources over the Internet. Due to novelty of cloud computing field, there is no many standard task scheduling algorithm used in cloud environment. Especially that in cloud, there is a high communication cost that prevents well known task schedulers to be applied in large scale distributed environment. Today, researchers attempt to build job scheduling algorithms that are compatible and applicable in Cloud Computing environment Job scheduling is most important task in cloud computing environment because user have to pay for resources used based upon time. Hence efficient utilization of resources must be important and for that scheduling plays a vital role to get maximum benefit from the resources. In this paper we are studying various scheduling algorithm and issues related to them in cloud computing. Index Terms: cloud computing, scheduling, algorithm
Load Balancing Algorithm to Improve Response Time on Cloud Computingneirew J
Load balancing techniques in cloud computing can be applied at different levels. There are two main
levels: load balancing on physical server and load balancing on virtual servers. Load balancing on a
physical server is policy of allocating physical servers to virtual machines. And load balancing on virtual
machines is a policy of allocating resources from physical server to virtual machines for tasks or
applications running on them. Depending on the requests of the user on cloud computing is SaaS (Software
as a Service), PaaS (Platform as a Service) or IaaS (Infrastructure as a Service) that has a proper load
balancing policy. When receiving the task, the cloud data center will have to allocate these tasks efficiently
so that the response time is minimized to avoid congestion. Load balancing should also be performed
between different datacenters in the cloud to ensure minimum transfer time. In this paper, we propose a
virtual machine-level load balancing algorithm that aims to improve the average response time and
average processing time of the system in the cloud environment. The proposed algorithm is compared to the
algorithms of Avoid Deadlocks [5], Maxmin [6], Throttled [8] and the results show that our algorithms
have optimized response times.

An adaptive algorithm for task scheduling for computational grideSAT Journals
Abstract
Grid Computing is a collection of computing and storage resources that are collected from multiple administrative domains. Grid resources can be applied to reach a common goal. Since computational grids enable the sharing and aggregation of a wide variety of geographically distributed computational resources, an effective task scheduling is vital for managing the tasks. Efficient scheduling algorithms are the need of the hour to achieve efficient utilization of the unused CPU cycles distributed geographically in various locations. The existing job scheduling algorithms in grid computing are mainly concentrated on the system’s performance rather than the user satisfaction. This research work presents a new algorithm that mainly focuses on better meeting the deadlines of the statically available jobs as expected by the users. This algorithm also concentrates on the better utilization of the available heterogeneous resources.

This document discusses using a particle swarm algorithm to enhance dynamic load balancing in a cloud computing environment. It begins with introducing centralized and decentralized load balancing approaches. It then describes using a particle swarm optimization technique, which identifies the least loaded, available virtual machine to distribute workload to in order to minimize energy usage and processing time. The document reviews several related works applying genetic algorithms, particle swarms, ant colony optimization and other approaches to optimize load balancing. It suggests a particle swarm algorithm can distribute load more efficiently compared to centralized and simple decentralized methods.
This document discusses different approaches to resource management in distributed systems, including task assignment, load balancing, and load sharing. The task assignment approach views each process as a collection of tasks and schedules the tasks across nodes to improve performance. The load balancing approach distributes processes across nodes to equalize workloads. The load sharing approach aims to ensure no nodes are idle while processes wait. Effective resource management requires algorithms that make quick decisions with minimal overhead while optimizing resource usage and response times.

Scalable Distributed Job Processing with Dynamic Load Balancingijdpsjournal
We present here a cost effective framework for a robust scalable and distributed job processing system that
adapts to the dynamic computing needs easily with efficient load balancing for heterogeneous systems. The
design is such that each of the components are self contained and do not depend on each other. Yet, they
are still interconnected through an enterprise message bus so as to ensure safe, secure and reliable
communication based on transactional features to avoid duplication as well as data loss. The load
balancing, fault-tolerance and failover recovery are built into the system through a mechanism of health
check facility and a queue based load balancing. The system has a centralized repository with central
monitors to keep track of the progress of various job executions as well as status of processors in real-time.
The basic requirement of assigning a priority and processing as per priority is built into the framework.
The most important aspect of the framework is that it avoids the need for job migration by computing the
target processors based on the current load and the various cost factors. The framework will have the
capability to scale horizontally as well as vertically to achieve the required performance, thus effectively
minimizing the total cost of ownership
Hybrid Scheduling Algorithm for Efficient Load Balancing In Cloud ComputingEswar Publications
This document presents a hybrid scheduling algorithm for efficient load balancing in cloud computing. The algorithm uses both round robin and priority-based scheduling approaches. It first assigns priorities to incoming job requests and then executes them in a round robin fashion. The algorithm aims to minimize overall response time and data center processing time. It is evaluated through simulation and found to perform better than round robin, priority-based, and equally spread current execution algorithms alone in terms of optimized response time and data center service time.
A Prolific Scheme for Load Balancing Relying on Task Completion Time IJECEIAES
In networks with lot of computation, load balancing gains increasing significance. To offer various resources, services and applications, the ultimate aim is to facilitate the sharing of services and resources on the network over the Internet. A key issue to be focused and addressed in networks with large amount of computation is load balancing. Load is the number of tasks„t‟ performed by a computation system. The load can be categorized as network load and CPU load. For an efficient load balancing strategy, the process of assigning the load between the nodes should enhance the resource utilization and minimize the computation time. This can be accomplished by a uniform distribution of load of to all the nodes. A Load balancing method should guarantee that, each node in a network performs almost equal amount of work pertinent to their capacity and availability of resources. Relying on task subtraction, this work has presented a pioneering algorithm termed as E-TS (Efficient-Task Subtraction). This algorithm has selected appropriate nodes for each task. The proposed algorithm has improved the utilization of computing resources and has preserved the neutrality in assigning the load to the nodes in the network.
This document discusses load balancing in cloud computing. It begins with an introduction to cloud computing and discusses how load balancing can improve user satisfaction and resource utilization by evenly distributing tasks across resources. It then describes different types of load balancing algorithms like round robin, equally spread current execution, min-min, and max-min algorithms. It also covers dynamic load balancing approaches like ant colony optimization and honeybee foraging behavior algorithms. The document concludes by comparing various load balancing algorithms based on metrics like throughput, fault tolerance, response time, overhead, and scalability. Load balancing is important for cloud computing to efficiently allocate dynamic workloads across nodes and improve performance.

The typical problem in product engineering is not bad strategy, so much as “no strategy”. This leads to confusion, lack of motivation, and incoherent action. The next time you look for a strategy and find an empty space, instead of waiting for it to be filled, I will show you how to fill it in yourself. If you’re wrong, it forces a correction. If you’re right, it helps create focus. I’ll share how I’ve approached this in the past, both what works and lessons for what didn’t work so well.
Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.

Abstract : Grid computing is new emerging technology which can be used to increase the performance of
Distributed Computing. It has emerged a new technology focusing on the resource sharing, utilizing
parallelism, and exploiting throughput managing and to reduce response time through proper distribution of the
application. Grid computing is a replica of distributed computing that uses geographically and disperses
resources. To increase performance and efficiency, the Grid system needs competent load balancing algorithms
for the distribution of tasks. The main goal of load balancing is to provide a distributed, low cost scheme that
balances the load across all the processors. In this seminar, the algorithm describes multiple aspects of load
balancing algorithm and introduced number of concepts which explains its broad capabilities. It also fulfils the
objectives of the grid environment to achieve high performance computing by optimal usage of geographically
distributed and heterogeneous resources.
Keywords: Grid Computing, Reliability, Resources etc.
I. INTRODUCTION
The rapid development in computing resources has enhanced the performance of computers and
reduced their costs. This availability of low cost powerful computers coupled with the popularity of the Internet
and high-speed networks has led the computing environment to be mapped from distributed to Grid
environments. In fact, recent researches on computing architectures are allowed the emergence of a new
computing paradigm known as Grid computing. Grid is a type of distributed system which supports the sharing
and coordinated use of geographically distributed and multi owner Resources , independently from their
physical type and location, in dynamic virtual organizations that share the same goal of solving large-scale
applications. In order to fulfil the user expectations in terms of performance and efficiency, the Grid system
needs efficient load balancing algorithms for the distribution of tasks. A load balancing algorithm attempts to
improve the response time of user’s submitted applications by ensuring maximal utilization of available
resources. The main goal is to prevent, if possible, the condition where some processors are overloaded with a
set of tasks while others are lightly loaded or even idle[1,4].
Grid computing, individual users can retrieve computers and data, transparently, without taking into
account the location, operating system, account administration, and other details. In Grid computing, the details
are abstracted, and the resources are virtualized. Grid Computing should enable the job in question to be run on
an idle machine elsewhere on the network. Grids functionally bring together globally distributed computers and
information systems for creating a universal source of computing power and information. A key characteristic of
Grids is that resources (e.g., CPU cycles and network capacities) are shared among various applications, and
therefore, the amount of resources available to any given application highly fluctuates over time. Load balancing
is a technique to enhance resources, utilizing parallelism, exploiting throughput improvisation, and to reduce
response time through an appropriate distribution of the application . Load balancing algorithm are two type
static and dynamic, Static load balancing algorithms allocate the tasks of a parallel program to workstations
based on either the load at the time nodes are allocated to some task, or based on an average load of our
workstation cluster. The decisions related to load balance are made at compile time[2,3].
II. DYNAMIC LOAD BALANCING
Load balancing is a technique to enhance resources, utilizing parallelism, exploiting throughput
improvisation, and to reduce response time through an appropriate distribution of the application. Load
balancing algorithms can be defined by their implementation of the following policies [1]:
Information policy: It states the workload of task information to be collected, when it is to be collected and
from where.
2. Fair Scheduling Algorithm With Dynamic...
54
Triggering policy: It determines the appropriate period to start a load balancing operation.
Resource type policy: It orders a resource as server or receiver of tasks according to its availability status.
Location policy: It uses the results of the resource type policy to find a suitable partner for a server or
receiver.
Selection policy: defines the tasks that should be migrated from overloaded resources (source) to most idle
resources (receiver).
Load balancing algorithms are defined by two types such as static and dynamic load balancing algorithms to
allocate the tasks of a parallel program to workstations. Multicomputer with dynamic load balancing allocate or
reallocate resources at runtime based on task information, which may determine when and whose tasks can be
migrated. In this seminar Dynamic Load Balancing Algorithm is implemented to multicomputer based on
resource type policy [1]. Load balancing feature can prove invaluable for handling occasional peak loads of
activity in parts of a larger organization. These are important issues in Load Balancing [1,4]:
• An unexpected peak can be routed to relatively idle machines in the Grid.
• If the Grid is already fully utilized, the lowest priority work being performed on the Grid can be temporarily
suspended or even cancelled and performed again later to make room for the higher priority work.
Load balancing should take place when the scheduler schedules the task to all processors. There are some
particular activities which change the load configuration in Grid environment. The activities can be categorized
as following:
• Arrival of any new job and queuing of that job to any particular node.
• Scheduler schedules the job to particular processor.
• Reschedule the jobs if load is not balanced
• Allocate the job to processor when it’s free.
• Release the processor after it complete the whole job
III. LOAD BALANCING APPROACHES
Load balancing problem has been discussed in traditional distributed systems literature for more than
two decades. Various algorithms, strategies and policies have been proposed, implemented and classified.
Algorithms can be classified into two categories: static or dynamic.
3.1 Static Load Balancing Algorithm
Fig.3.2: Static Load Balancing
Static load balancing algorithms allocate the tasks of a parallel program to workstations based on either
the load at the time nodes are allocated to some task, or based on an average load of our workstation cluster. The
decisions related to load balance are made at compile time when resource requirements are estimated. The
advantage in this sort of algorithm is the simplicity in terms of both implementation as well as overhead, since
there is no need to constantly monitor the workstations for performance statistics. However, static algorithms
only work well when there is not much variation in the load on the workstations. Clearly, static load balancing
algorithms aren’t well suited to a Grid environment, where loads may vary significantly at various times [1,2,4].

3.2 Dynamic Load Balancing Algorithm
Fig.3.3: Dynamic Load Balancing
Dynamic load balancing algorithms make changes to the distribution of work among workstations at
run-time; they use current or recent load information when making distribution decisions. Multicomputers with
dynamic load balancing allocate/reallocate resources at runtime based on no a priori task information, which
may determine when and whose tasks can be migrated. As a result, dynamic load balancing algorithms can
provide a significant improvement in performance over static algorithms. However, this comes at the additional
cost of collecting and maintaining load information, so it is important to keep these overheads within reasonable
limits [1,2,4].
IV. SCHEDULING AND LOAD BALANCING
4.1 Fair Scheduling
The scheduling algorithms do not adequately address congestion, and they do not take fairness
considerations into account. Fairness is most essential for scheduling of task. In Fair Scheduling, the tasks are
allocated to multiple processors so that the task with unsatisfied demand get equal shares of time is as follows :
• Tasks are queued for scheduling according to their fair completion times.
• The fair completion time of a task is estimated by its fair task rates using a max min fair sharing algorithm.
• The tasks are assigned to processor by increasing order of fair completion time.
In this algorithm, tasks with a higher order are completed first which means that tasks are taken a higher priority
than the others which leads to starvation that increases the completion time of tasks and load balance is not
guaranteed. For this issue we propose a Load Balance (LB) Algorithm to give uniform load to the resources so
that all tasks are fairly allocated to processor based on balanced fair rates. The main objective of this algorithm
is to reduce the overall make span [1,5,6].

V. RESULTS AND DISCUSSION
When we started a work on our project, our main aim was to evaluate performance of various resources
with various scenarios, the concept lies when evaluating performance is to have various scheduling algorithm
and various resources with different characteristics. As the grid has become very popular in its short period of its
emergence, the usage of performing scheduling operation is not up to the mark because the scheduling process
exists as of now is only minimal i.e., when anyone trying to perform a operation he should make the system or
scheduler to know the jobs which it has to be scheduled in advance. So this is not a permanent solution in this
kind of environment. After having done a extreme literature survey we have started working on evaluating
performance of the system with various scheduling algorithms such as FCFS, Earliest Deadline First, Easy Back
filling and so on., our work is not only performing scheduling process though evaluating the performance is the
major issue in our project but before that we have found a way to create a Jobs and Resource, after creating Jobs
and resource with various characteristics, these has been used as the input for our processing. Finally each and
every jobs has been given to the resources in order of not keeping any of machines idle i.e., jobs will be
allocated to the machines based on their availability.
The GridSim toolkit provides a comprehensive facility for simulation of different classes of
heterogeneous resources, users, applications, resource brokers, and schedulers. It can be used to simulate
application schedulers for single or multiple administrative domains distributed computing systems such as
clusters and Grids. Application schedulers in the Grid environment, called resource brokers, perform resource
discovery, selection, and aggregation of a diverse set of distributed resources for an individual user. This means
that each user has his or her own private resource broker and hence it can be targeted to optimize for the
requirements and objectives of its owner. In contrast, schedulers, managing resources such as clusters in a single
administrative domain, have complete control over the policy used for allocation of resources. This means that
all users need to submit their jobs to the central scheduler, which can be targeted to perform global optimization
such as higher system utilization and overall user satisfaction depending on resource allocation policy or
optimize for high priority users.
VI. CONCLUSION
This algorithm has proved the best results in terms of makespan and Execution Cost In particular the
algorithm allocates the task to the available processors so that all requesting task get equal amount of time that
satisfied their demand. Through this proposed algorithm, we have described multiple aspects of load balancing
algorithm and introduced numerous concepts which illustrate its broad capabilities. Proposed algorithm is
definitely a promising tendency to solve high demanding applications and all kinds of problems. Objective of
the grid environment is to achieve high performance computing by optimal usage of geographically distributed
and But grid application performance remains a challenge in dynamic grid environment. Resources can be
submitted to Grid and can be withdrawn from Grid at any moment.
