INFSO-RI Enabling Grids for E-sciencE User Survey Objectives and Results F.Jacq CNRS-IN2P3 EGEE Conference - Athens 21 th April 2005

Enabling Grids for E-sciencE INFSO-RI User Survey:Objectives and results 2 User Survey : Objectives To evaluate user satisfaction for milestone MNA4.3. This is a specific request of the reviewers. User Survey Content –Parameters for survey analysis : User identification, User and application profile –User satisfaction : Benefits in using EGEE, Quality of the grid, Quality of the user support, Quality of the documentation User Survey available on line :

Enabling Grids for E-sciencE INFSO-RI User Survey:Objectives and results 3 The population of users What was the target ? –All users of the grid were invited to fill the user survey – to mailing list community : Biomed and Generics –We have also some reply of dteam members, infngrid (word of mouth ! ) Expectations of reply –Biomed Community : estimation of 35 active users –Generics Community : estimation of 40 active users

Enabling Grids for E-sciencE INFSO-RI User Survey:Objectives and results 4 Global Results : User identification (1/2) 39 Replies with 33 from Biomed and Generics : Who are they ? NA4 application management NA4 user support Dteam members (Test team, End User Support, Site Administrator) Response Rate of Biomed 63% Response Rate of Generics 27%

Enabling Grids for E-sciencE INFSO-RI User Survey:Objectives and results 5 Global Results : User identification (2/2) How do they use the grid ? –Writing application themselves : 94 % –Launching jobs themselves : 86 % –Using Genius : 18 % (induced by the low replies of generics application) –They launch jobs per month :  Average : 170  Minimum : 1  Maximum : 1200  Duration of a job :

Enabling Grids for E-sciencE INFSO-RI User Survey:Objectives and results 7 Service Grid Satisfaction Global Satisfaction with use of grid Estimated of jobs failure : 18% 46%

Enabling Grids for E-sciencE INFSO-RI User Survey:Objectives and results 8 User Support Satisfaction 67% 62% 72% => Quality Support good satisfaction for > 65 % Global Satisfaction of the user support

Enabling Grids for E-sciencE INFSO-RI User Survey:Objectives and results 9 Global Satisfaction of the documentation Documentation Satisfaction => Except System manual documentation, the satisfaction is intermediate 33% 63% 30% 27%

Enabling Grids for E-sciencE INFSO-RI User Survey:Objectives and results 10 Users Expectations Users are mainly waiting for :

Enabling Grids for E-sciencE INFSO-RI User Survey:Objectives and results 11 Grid added value Is it possible to do the same work without EGEE ? Real Benefits of functionality with EGEE : –Job management : Resource broker, reduction of execution time for a large number of jobs, requirements attributes –Pervasive and transparent access to large scale and distributed resources –Data management : registration, file access, virtualization of storage –Secure environment

Enabling Grids for E-sciencE INFSO-RI User Survey:Objectives and results 12 Improvement of EGEE Major requirements for EGEE improvement: –Stability : Resources, nodes, RB, RM –Job management :  Collection of jobs  System priority of jobs  Automatic management of thousands jobs  Reduction of the waiting time  Capability to "chain" RBs and then suppress SPOF –Data management :  Shared file  Avoid the files and space number limitations on nodes  Management of Relational DataBases –Security :  Data, jobs and users,  Secure access to external (meta-) databases,  Fine granular security, ACLs –MPI on more sites support for MPI-based parallel execution –Integrated and standard debugging facilities for all commands –Co allocation of CPUs for interactive jobs

Enabling Grids for E-sciencE INFSO-RI User Survey:Objectives and results 13 Conclusions and Roadmap Conclusions –Satisfaction  Support : quite good  Grid Service : intermediate satisfaction  Documentation : has to be improved –Diversity of applications => complexities, benefits and requirements are heteroclites. Roadmap –Improvement of the user survey –HEP community
