Tamas Kiss – kisst@wmin.ac.uk EGEE ’09, Barcelona, 22 nd September 2009 – Application Porting and User Support 2 The problem we address Desktop grids (DGs) (volunteer DGs – home computers, organizational DGs – institutional desktops) Inexpensive, very large number of CPUs (~100K – 1M) Bag of task appls Cluster based service grids (SGs) (EGEE, OSG, etc.) Moderately expensive, moderate number of sites and CPUs any appls Supercomputer based SGs (DEISA, TeraGrid) Very expensive, small number of sites and large number of CPUs MPI appls OGF GIN EDGeS

5. Tamas Kiss – kisst@wmin.ac.uk EGEE ’09, Barcelona, 22 nd September 2009 – Application Porting and User Support 5 The EDGeS Application Support Service Aims and objectives: –facilitate the porting of applications to the EDGeS infrastructure by targeting user communities already associated with EGEE or DGs new user communities Activities: –develop a generic methodology for application porting –identify user communities that require the power of the EDGeS infrastructure –provide a service in order to aid the migration to and running of applications on the EDGeS infrastructure

6. Tamas Kiss – kisst@wmin.ac.uk EGEE ’09, Barcelona, 22 nd September 2009 – Application Porting and User Support 6 Why do we need a methodology? Motivations Grid application development is very often ad-hoc – –Developers do not follow any methodology – –Poorly documented systems – –User expectations not fulfilled Systems design and development methodologies are too generic – –Special focus is required when porting/developing an application to a SG/DG platform EADM: EDGeS Application Development Methodology

10. Tamas Kiss – kisst@wmin.ac.uk EGEE ’09, Barcelona, 22 nd September 2009 – Application Porting and User Support 10 What is an EDGeS application? An EDGeS application is capable using both Service (EGEE) and Desktop Grid resources EDGeS application scenarios: 1.Application runs on DG and uses EGEE resources via the DG to EGEE bridge 2.Application submitted to EGEE and uses DG resources via the EGEE to DG bridge 3.Application uses both SG and DG resources via an external scheduling and job submission system (not through the EDGeS bridges) EDGeS application

11. Tamas Kiss – kisst@wmin.ac.uk EGEE ’09, Barcelona, 22 nd September 2009 – Application Porting and User Support 11 Scenario 1 – DG to EGEE via bridge DG user Desktop Grid EGEE EDGeS VO WMS and other EGEE services DG->EGEE bridge User entry point is DG – using EGEE is completely transparent from user’s point of view

12. Tamas Kiss – kisst@wmin.ac.uk EGEE ’09, Barcelona, 22 nd September 2009 – Application Porting and User Support 12 BOINC Server BOINC workers UoW Local Desktop Grid Pulls work units Submits as job to EGEE BOINC to EGEE bridge EGEE EDGeS VO WMS Adds user credentials Define input parameters and number of work units End User gUSE WS P- GRADE portal G-USE DG Submitter submits jobs and retrieve results via 3G Bridge Workers: Download executable and input files Upload: result Protein Molecule Simulation on a BOINC based Desktop Grid

13. Tamas Kiss – kisst@wmin.ac.uk EGEE ’09, Barcelona, 22 nd September 2009 – Application Porting and User Support 13 Scenario 2 – EGEE to DG via bridge EGEE user (using EGEE UI machine or portal) Desktop Grid 1 EGEE VO WMS and other EGEE services − −User entry point is EGEE − −using DG is transparent from user’s point of view Desktop Grid n Edges Services DG CE + EDGeS AR

14. Tamas Kiss – kisst@wmin.ac.uk EGEE ’09, Barcelona, 22 nd September 2009 – Application Porting and User Support 14 Porting to EDGeS: 1. 1.Develop DG version of application 2. 2.Test DG version and write test report Use the EDGeS Development DG Use your own development DG Test report template downloadable from EDGeS website 3. 3.Have your application validated Validation is done by EDGeS Validation Team Outcome: validation document Validation includes tests via the EDGeS EGEE->DG test bridge 4. 4.Publish your application in EDGeS Application Repository EDGeS Services (AR and EDGeS CE) should be deployed by your EGEE VO as pre-requisite DG Admins can download your application from EDGeS AR if they are ready to support it Scenario 2 – EGEE to DG via bridge

15. Tamas Kiss – kisst@wmin.ac.uk EGEE ’09, Barcelona, 22 nd September 2009 – Application Porting and User Support 15 Which EGEE applications are suitable for EDGeS? EDGeS applications should run on both EGEE and DGs –EGEE supports a much wider scale of applications than DGs –We should assure that the application runs on DGs Requirements towards an EGEE application to be executable on DGs: –Parallelization: Only master/worker or parameter sweep parallelisation –No MPI or internal communication between worker nodes –Nodes can only use the results of other nodes through the server –Data handling: small or medium-sized (max. 100 MB per worker) inputs and outputs No shared data storage No confidential data (sent down to potentially un-trusted worker)

16. Tamas Kiss – kisst@wmin.ac.uk EGEE ’09, Barcelona, 22 nd September 2009 – Application Porting and User Support 16 Application examples – Scenario 2 EDGeS application examples: – –EMMIL E-marketplace application – run on SEE-Grid already – –VisIVO - Visualisation Interface to the Virtual Observatory – EGEE application by Astrophysical Observatory of Catania, currently ported to DG by UoW – –3D video rendering – application ported to EGEE (however, DG version already existed)

17. Tamas Kiss – kisst@wmin.ac.uk EGEE ’09, Barcelona, 22 nd September 2009 – Application Porting and User Support 17 Scenario 2 – an example EMMIL – E-Marketplace Model Integrated with Logistics three sided negotiation between buyers, sellers and third party logistics providers Aims to optimise the total coast Ported to EGEE as a parameter sweep application in the SEE Grid project Large matrix solving – matrix can be separated and solution parallelised Ported to EDGeS using GenWrapper

18. Tamas Kiss – kisst@wmin.ac.uk EGEE ’09, Barcelona, 22 nd September 2009 – Application Porting and User Support 18 Scenario 3 – SG/DG resources but not through EDGeS bridges Using external job submission and scheduling system to submit jobs to both EGEE and DG resources – –G-USE portal supports this scenario by default E.g.: – –CancerGrid application uses EGEE and DG resources via the g-USE portal (but not through the bridges - see presentation on Friday afternoon) – –Could be justified with specific user requirements E.g.: – –WISDOM project uses only pull jobs on EGEE that are unsuitable to be bridged to DG – –Both solutions use EDGeS technology: 3GBridge

Tamas Kiss – kisst@wmin.ac.uk EGEE ’09, Barcelona, 22 nd September 2009 – Application Porting and User Support 19 Scenario 3 – e.g. DG submitter for WISDOM WISDOM: Meta middleware to submit pull (pilot) jobs to EGEE The DG submitter: – –Submit push (direct) jobs to the DG when EGEE resources are overloaded WISDOMJobManager 3G Bridge WSSubmitter 3G Bridge Bridge UoWBOINC EDGeSSubmitter Push jobs WISDOMTaskManager WISDOM Desktop Grid EGEE Submitter Pull jobs EGEE EGEE
