2 Is a Grid Scheduler or Grid Metascheduler capable of Scheduling jobs to physical resources Creating virtual machines in a remote potential physical resource to meet the CPU requirement of an application Creating Virtual Cluster in a remote potential physical resource to meet applications platform requirement 22/6/2014

3 On the fly creation of execution environment using appropriate VM images Dynamically create grid/cluster environment by automating globus installation and configuration Can create virtual machine and attach it to a existing cluster 32/6/2014

4 Motivation Application often requires number of CPUs that cannot be met by a single cluster Create virtual machines to meet the additional requirements of CPUs to execute the application Connect them to the selected cluster Application often requires a completely different software environment that no cluster in the grid can provide Create virtual clusters dynamically, deploy grid middleware, deploy necessary OS and software, execute the application Users CRB Resource A Resource N … 42/6/2014

6 Controller takes decision on scheduling strategies, initiates appropriate services to create VMs and Virtual Cluster,Selecting suitable resource for application execution. Monitors the status of physical and virtual resources, implements necessary services for creating virtual machines and virtual clusters, monitors application execution in it. These are services implemented in every physical resource for creating virtual clusters, VMs, and VM information aggregation 62/6/2014

9 M.I.T, Anna Univ The resource brokering is purely depends on the resource ontology in which relationship between all concepts of Grid/Cloud domain is represented and established with the help of properties. Resource Description – The descriptions should be added with resources for better discovery in a Grid/Cloud environment. Resource Description Language (RDL) should follow the standards like Resource Description Framework (RDF) and Web Ontology Language (OWL) that has been used for Semantic web & Semantic Cloud as well. Resource Discovery 92/6/2014

11 M.I.T, Anna Univ The core component of the semantic component is Grid Resource Ontology template. An ontology template is a domain specific ontology it provides hierarchy of concepts along with properties to define their characteristics. Ontology is used for understanding the domain information. It describe the concepts in the domain and also relationships that grip between those concepts. OWL (web ontology language) has been widely used for creating the ontology.

15 GROningen MAchine for Chemical Simulation (GROMACS) is a very powerful toolbox in modern molecular modeling. It was originally developed at the University of Groningen, and it is mainly designed for testing of biochemical molecules like lipids, proteins and nucleic acids, which has lot of complex bonded interactions. It is mainly used to understand the structure, dynamics and motion of individual atoms. The two most commonly used methods are energy minimization and molecular dynamics that optimize the structure and simulate the natural motion of biological macromolecules. It converts molecular coordinates from a Protein Data Bank (PDB) file into its internal format. 2/6/201415

16 The whole simulation process consists of seven steps as given below: Creation of topology files using Protein Data Bank (PDB) file Solvating the protein Energy Minimization Equilibration run Performing MD simulation Viewing Trajectory files Viewing MD simulation results 2/6/201416

20 Supports JSDL specification for job submission. Provides a graphical user interface for job submission, monitoring and viewing resource information. Semantic Description and Discovery of Grid and Cloud resources – solving interoperability problem. Supports DAG, MPI and Batch jobs. Creation of virtual cluster formation with either PBS or SGE as local resource manager in Grid as well as Cloud resources. Its capability to create virtual machines on the fly will also improve the scalability. This feature can also be applied to cloud resources while hosting a server application in which one has to increase the hardware resources dynamically depending on the need. 202/6/2014
