1 Supporting scientific and Web 2.0 communities by desktop grids P. Kacsuk MTA SZTAKI (Univ. of Westminster) The EDGeS/EDGI projects receive Community research funding 1

2 The strength of communities Web 2.0 services provide frameworks for communities to put together contents Volunteer computing (VC) is a community activity to provide desktop resources for typically scientific communities -> Desktop Grids (DGs( DGs) Our goal is to bring together the two communities: Web 2.0 communities can help scientific projects to advertise their projects and attract volunteer donors Web 2.0 communities can extend the scope of their applications by using VC technology provided for science Web 2.0 service providers can increase their services without further resource investment 2

3 Goals of the EDGI and Web2Grid projects To support both scientific and Web 2.0 communities by desktop grids EDGI: enables scientific communities to extend the existing service grids (SGs( SGs) with DG resources Web2Grid enables Web 2.0 communities to create large computing infrastructure as community effort 3

4 Possible options to extend the infrastructure for communities Scientific U1 Community U2 Un U1 U2 Um Users Web 2.0 Community Users Grid Faster, more Cloud DG reliable but more expensive D1 D2 Donors Dj Web 2.0 Community Service Cloud DG D1 D2 Donors Dk Less expensive since uses the free cycles of existing PCs 4

5 EDGeS scope only for compute intensive applications for EGEE (glite) EDGI: Extending the grid infrastructure for scientific communities EDGI scope for both compute and data intensive applications for EMI/EGI (glite, ARC, Unicore) Extend Desktop Grids with Clouds for QoS 5

6 Extending the grid infrastructure for scientific communities U1 U2 Un Scientific Community Users Grid Faster, more Cloud DG reliable but more expensive D1 D2 Donors Dj Cloud Provides reliable donors from dedicated cloud resources 6

7 Extending the grid infrastructure for scientific communities U1 U2 Un Scientific Community Users Grid DG D1 D2 Donors Dj Cloud Provides reliable donors from dedicated cloud resources 7

8 Steps of the technical solution The starting state DG Project DG client submit glite grid Volunteer/ Institutional Resources 8

9 SG -> > DG direction Security issues In DG projects Applications are trusted DG server is trusted Clients are not trusted Therefore any SG application that is intended to run in a DG should be validated to make it trusted Therefore EDGI provides: Application validation service Application repository (AR) where trusted applications are stored EDGI bridge transfers only those applications to DGs that are stored in the AR 9

10 Step 1: Providing application repository metadata templates describe applications and their implementations to support browse and search operations access without registration for all users to browse and search the repository API to enable repo access for modified CEs 10 10

11 Step 2: Submit job from glite to DG project DG Project download 3GBridge DG client submit glite grid Volunteer/ Institutional Resources 11

17 Host A 3G Bridge 3G Bridge Extension for supporting Clouds Queue 1 BOINC Plugin BOINC Master Cloud Resource N (BOINC Worker) Queue 2 Cloud Plugin Amazon/ Eucalyptus Cloud Interface Cloud Resource 2 (BOINC Worker) Cloud Resource 1 (BOINC Worker) Scheduler 1. Job is submitted from MCE to 3G Bridge. 2. 3G Bridge submits the job to a BOINC DG using the BOINC Plugin 3. The Scheduler keeps track of the number of jobs in the BOINC queue (Queue 1) and of the number of the running Cloud Resources (workers). 4. If the BOINC DG is overloaded, the Scheduler starts new workers by submitting a job to the queue of the Cloud Plugin (Queue 2). 5. Each job in Queue 2 launches a new BOINC Worker in the Cloud. 6. If the cluster is underutilized, the Scheduler stops some workers (cloud resources) by sending cancel jobs into Queue 2. Legend Job Command Information 17

20 EDGI business model U1 U2 Un SC Users can ask QoS support (cloud resources) if they have collected credits Institutes of SC users can donate DG resources and can collect credits (by BOINC mechanism) Students and public can support universities by offering their credits Grid DG D1 D2 Donors Dj Cloud EDGI provides reliable donors from dedicated cloud resources After EDGI, IDGF members or cloud providers can provide cloud resources 20

21 EDGI business model U1 U2 Un DG Grid Universities can create local DGs (e.g. Univ. of Westminster, Univ. of Portsmouth, Univ. of Szeged, etc.) University level DG could be connected to the EDGI DG and collect credit for the univ. researchers DG D1 D2 Donors Dj Cloud D1 D2 Donors Dk 21

27 Possible business models Service provider provides the whole framework Supplier model: Service provider invites trusted individuals to connect clients Pays for the collected credits Volunteer model: Web 2.0 community members provide the clients They collect credits Credits are transferred to real money and offered to charity organizations 27

28 International Desktop Grid Federation (IDGF) Support those NGIs that want to extend their VO with volunteer or local DGs Support those universities, institutes, companies who want to set up local DG Run dissemination campaign to attract more volunteers to donate their computer resources Federation is open for organisations and individuals in research and industry. Current members: >100 individuals > 30 organizations (including companies) Introduction Author: Robert Lovas, Ad Emmen RI WP4 version:

29 Summary Volunteer DG resources can be provided for scientific and Web 2.0 communities as an inexpensive alternative to cloud resources EDGI and Web2Grid projects have developed the required technical solutions They also show possible business models Future task: to implement the business models 29
