Activities and Work Packages


WP5 Objectives• To provide a Grid-aware infrastructure on which

the Health-e-Child applications can operate

• To develop appropriate APIs for applications to invoke Grid services

• To provide education to application developers on the use and operation of the Grid infrastructure

• To ensure that updates and releases of the Grid platform are available as the infrastructure evolves


Challenges

• Security:• Strong authentication

• VOMS based authorization to all Grid resources

• Fine-grained data sharing/access. Granularity:• File

• DB views, tables, table rows


Early Faced IssuesMainly Non-Functional since project has just started

• Selecting grid m/w services wrt project requirements• Lots of services/functionalities available• Different implementations with different levels of maturity

• Clustering grid m/w services• To reduce the h/w requirements & maintenance (1 server / Hospital)• To facilitate deployment (3 clinical sites + at least 5 institutional sites)

• Decentralisation of grid m/w services• Sites need to be as much as possible autonomous

• “Griddification” of Applications• Some of the HeC applications might be “gridified”

• Griddification has to be balanced against runtime and development complexity criteria


Current Investigations• Selecting grid m/w services wrt project requirements

=> Services selection based on URS + Grid Questionnaire

• Clustering grid m/w services=> “Xenification” of OSs + clustering services wrt functionality

• Decentralisation of Grid Services=> Dependent on gLite developments, but already some possibilities with Master/Slave

configurations

• “Griddification” of Applications=> Introduced a classification of applications. Grid Questionnaire will certainly help in

making decisions

• Grid Access=> Abstracting grid access through dedicated service


Remaining Challenges

• Data Integration in Hospitals (post phase 2)• What mechanisms to use? What will be the limitations (in particular with proprietary

systems?

• Patient Data Distribution & Sharing• What technology/implementation?

• Patient Image Files Sharing• Enabling the sharing of large files over the internet

• MRI @ GOSH = 500MB/patient• CT @ NECKER = 3.5GB/patient …raises bandwidth problems

• Griddification of Applications• Appears relevant for computation heavy algorithms or batch processing

• However many clinical algorithms have short runtime (e.g. image processing, since clinicians need almost instantaneous results)


Non-functional Requirements• Hospital Sites should be autonomousautonomous

• Sites should not depend on any central services• Hardware requirements remain too high for Hospitals

• Getting access to the grid through one boxone box would be ideal• e.g. 1 Server per Hospital1 Server per Hospital

• Fine-grained security mechanism for accessing data (at the record level?)

Functional Requirements• PseudonymisationPseudonymisation as a native middleware service?• Native StreamingStreaming facilities for sharing large DICOM files• [ Native patient-centricpatient-centric data model(s)

• (flexibility) Optionally data model could be selected from existing standards (e.g. HL7…) or even created from scratch

• (interoperability) Optionally a native commodity for exporting/exposing data through different data models would be nice (model-driven)

• (interoperability) Optionally a data model (schema) discovery mechanism could help• Native connectors to external backends for batch data integration ]

Clinician’sHeC Identity

Approach (1)


HeC Platform Centralized


HeC Platform DeCentralized


Approach (2)• An intermediary access layer: the HeC Gateway

• To decouple client applications from the complexity of the grid and other computing resources

• Towards a platform independent implementation• Domain Specific Functionality exposed in the HeC Gateway• Grid mainly used as a Distributed & Federated PACS

• Different modalities of images to be anonymised and shared • Clinical Reports• Misc. Files
