Grid Computing Projects

Grid Computing Projects Gridsim is a java toolkit based on simjava library. We offer gridsim projects for PhD to simulate heterogeneous resource with various user, application and local scheduler. We provide gridsim academic projects for PhD with centralized & decentralized resource broker use scheduling algorithm/policies mapping job resources to optimistic system or user objective based on goal. We support are research scholars those who interested to do research in network domain. We determine gridsim projects for PhD to implement thesis in network. We develop new methods based on research interest and requirements.

Gridsim toolkit:

We ensure toolkit as:

It provide feature for application composition, interface for assign application to resources and information service for resource discovery.
It is a java based discrete event grid simulation package. It ensures ability to model heterogeneous computation.

Gridsim in network model:

We implement gridsim network model from ACM papers as:

Generate background traffic.
Allow user to generate network topology.
Incorporate various level of service to send packets.
Packet data into smaller chunks to send over network.

Features of gridsim:

We endorse following features are:

Support reservation based mechanism for resource allocation
Provide clear & well define interface to implement various resource allocation algorithms
Allow modeling of different resource characteristics and types
Ability to schedule compute/data intensive jobs
Enable simulation of workload traces from real supercomputers
Allocate income job based on space or time shared mode

Gridsim in network projects:

We developed more than 95+ projects in gridsim by our team in an efficient way. The network components are:

Input and output:

Gridsim entities want to send/receive data and use as input and output entities.
I/O entities act as buffer to hold packets until a link is free.

Packet scheduler:

It is responsible to decide order when one or more packets will send downlink

Link:

We represent link in gridsim as abstract class link for extensible. We require information about propagation delay and MTU for packet delivery.

Packet:

Gridsim network packet represented as interface class packet.

Router:

We represent router in gridsim as abstract class router for flexibility it done by static table or dynamic method such as RIS & OSPF.

Quality of service and routing information:

We support requesting network status during runtime as number of hops to destination, bottleneck bandwidth and round trip time (RTT).

Simulation with background traffic:

We support gridsim with background traffic model. By class traffic generator we generate packet size, number of packets and inter arrival time.

Interadion among gridsim network components:

It is similar to user datagram protocol every entity in gridsim is attack to it and act as buffers. We use this to send packets in datagram oriented protocol.
