Applying OO Techniques

• Service activity is a special object of type
  Exertion
• Exertions are executed by network objects/service
  providers of type Servicer
• Service providers form P2P environment
• Service is requested by calling the method
  service(Exertion)
• Service providers are identified by a type with
  methods
• public ServiceContext selector(ServiceContext)

4
Exertion Interface

• All service activities implement this interface

public interface Exertion // Apply this
exertion method to the specified context public
Exertion exert() throws RemoteException,
ExertionException
5
Service Peer Interface Servicer

• All services implement this interface

public interface Servicer // Put into action
the specified exertion public Exertion
service(Exertion exertion) throws
RemoteException, ExertionException //

Self-Aware Grid

• A grid federation knows what is doing
• Learn from experience and adapt to surprises
• Is aware of its behavior and explain itself
• Is able to anticipate different scenarios and
  predict and plan for novel futures
• It would learn, not crash, when faced with a new
  situation
• Self-testing, self-debugging, and self-explaining
  within a federation

48
What is Rio?

• A Dynamic Service Delivery architecture based on
  the capability to provision services through the
  network using Qualitative and Quantitative QoS
  attributes
• Addresses essential issues for the development of
  a dynamic self healing services environment

49
RIO Autonomous Computing

• Dynamic, Distributed systems
• - Capability to adapt to unforeseen changes on
  the network
• - Driven by increasing componentization,
  distribution heterogeneity
• Scale to orders of magnitude
• Dynamic Policy driven systems
• - Injecting rules policies into the service
  fabric allowing greater automation, scalability
  and controlled behavior
• Telemetry
• - Being able to monitor, meter, gauge and observe
  stimulus through the system
• - Not just machine based, but network-wide

50
Rio Architecture Overview
51
Jini Service Bean Basics

• Jini Service Beans (JSBs) are the fundamental
  domain specific computational entities on the
  network
• JSBs are Java objects
• JSBs can encapsulate access to NDI (legacy)
  components
• Provides an easy to use programming model while
  maintaining access to low-level APIs
• Are provisionable based on their QoS attribute

52
Cybernode

• Jini Service Beans are instantiated by Cybernodes
• Cybernodes run on computational resources
• Cybernodes can contain multiple service beans
• Address lifecycle issues, including development,
  deployment, and runtime
• Provides the basic infrastructure to load,
  instantiate and destroy Jini Service Beans

54
Operational String

• Aggregated collection of application and/or
  infrastructure software assets that when put
  together provide a specific service on the
  network
• An Operational String is an object graph
  composed of objects that provide context on how
  to provision and instantiate services
• Can be created by referencing an LDAP
  repository, serialized objects, or from
  structuredXML documents (there can be many
  other sources as well)

Quality of Service

• Approach
• Software components need to run on most
  appropriate compute resource based on definable
  criteria
• Compute resources have capabilities
• CPU, Disk, Connectivity, Bandwidth,
• Rio provides an extensible model allowing the
  declarative association of QoS

56
Provision Manager

• Provide a provisioning model to dynamically
  deploy, monitor manage service components as
  described in an Operational String
• Implement a Fault Direction and Recovery strategy
  for service components
• Provide pluggable load distribution and Resource
  Cost analysis mechanisms to effectively take use
  of resources on the network

57
Dynamic Provisioning
discover
Discover/join
Load an Operational String from disk or via
remote method invocation
notify
Register/update for provision notifications with
QoS attribute
Service Instantiator
Provision Manager
Notify ServiceInstantiation resources with a
ServiceProvisionEvent based on the assignability
of the JSBs QoS to the ServiceInstantiation
resources QoS
Start a monitor for each service in an
Operational String
Service Bean Instantiator
Fire notification events to event registrants for
added, removed, updated Operational String
actions as well as failed Provision attempts
As needed download JSB class files
Instantiate initialize JSB

SGrid Dispatcher UI

• Choose the Application to run (For example Proth)
• Specify the Job Size for the jobs
• Set the Arguments, Attributes and Executables for
  the application

75
Arguments

• Specify Arguments, Input Files, Output Files for
  the Application
• Can be added above or below the selected option
• Can be reordered according to users requirement
  (Up, Down, Delete buttons)

76
Executable Attributes

• Specify which caller to use for execution,
  depending upon its
• Location (HPCC, SORCER)
• Host Name (129.118.56.61)
• Operating System
• Node Name (Amber)
• is the default option which indicates that
  the application can be run by any caller in the
  Federation

77
Executables - Windows

• Specify Windows Executables and Library Files
• The files can be dynamically downloaded from File
  Store

78
Grid Provider

• A Grid Provider is responsible for
• SGrid Publishing ServiceUI
• Accepting user inputs and creating a Job
• Submitting the Job to Jobber
• Receiving results, notifying client, getting
  inputs and storing results in the File Store
• Advantages of such a design
• User friendly with respect to the Job Editor UI
• Zero install with a Jini service browser and a
  web-based File Store user agent

79
Caller Provider

• A Caller receives a caller service context that
  abstracts any system call across different
  platforms (Solaris/Linux/Windows)
• Callers are capable of
• Downloading platform specific executable binaries
  and libraries
• Downloading source and compile it on-the-fly
• Make system calls with arguments specified in the
  service context
• Callers download/upload files from/to the SORCER
  File Store Provider

Distributed BLAST in SORCER

• Introduction
• BLAST (Basic Local Alignment Search Tool) is a
  sophisticated software package used in
  Bioinformatics and Sequence Analysis for rapid
  searching of nucleotide and protein databases
• BLAST is powerful and has been optimized for
  performance however the public sequence
  databases are big and growing rapidly . Thus, it
  takes a huge amount of computer resources to
  search sequence queries in a large database
• As a solution to this problem we provide an
  implementation of BLAST in a distributed
  environment using SORCER
• Goals
• To increase performance by making the BLAST
  Process Distributed and sharing idle CPU and
  other resources
• Focus on high throughput of large numbers of
  submissions instead of high performance on any
  single job
• Provide a working system that is easy to Install
  and Use
• Heterogeneous network- provide a portable system
  that can be installed on different Compute
  devices
• The Business Logic is separate from the whole
  framework. All Libraries and Business Logic Code
  is Downloaded.
• Self-healing environment, can overcome crashes
  i.e. fault detection and recovery
• Enable large batch BLAST processes distributed
  over regular WAN or LAN
