VIP: design and implementation of the portal and execution service
Goal: Self-Healing vs No-Healing Cope with recoverable errors
Metrics Makespan of the activity execution
Resource waste
For w < 0: self-healing consumed less resources
For w > 0: self-healing wasted resources €
w =(CPU + data) self −healing(CPU + data)no−healing
−1
Self-Healing process reduced resource consumption up to 26% when compared
to the No-Healing execution R. Ferreira da Silva, T. Glatard, F. Desprez, Self-healing of operational workflow incidents on distributed computing infrastructures, IEEE/ACM International Symposium on Cluster, Cloud and Grid Computing (CCGrid), Ottawa, Canada, 2012.
VIP – Facts 321 registered users, from
38 countries
Most used portal certificate in EGI (August 2012) https://wiki.egi.eu/wiki/EGI_robot_certificate_users
Consumed 379 CPU years from January 2011 to August 2012 http://accounting.egi.eu
1/10 of the total activity of the biomed international VO. One of the most active users

Repartition of application executions in VIP (Nov 2011 – Oct 2012)
1155 executed simulations during the last year (~3/day)
Applications
Repartition of portal users on EGI (August 2012) (source: https://wiki.egi.eu/wiki/EGI_robot_certificate_users)
Users
Concluding remarks VIP is an openly-accessible web portal for multi-modality
medical image simulators MRI, US, CT and PET and other tools Workflow execution on EGI Access to storage resources High–level interface for non-experts
No IT required (Software as a Service)
Facts 321 registered users from 38 countries Consumed about 400 CPU years / year
Limits and perspectives Fair resource allocation among workflows User support Heavy data transfers
