Outline

• WS-PGRADE/gUSE in a nutshell• Flexibility of:

– Parallelism– Compute infrastructure access– Data storage access– Customization possibilities

• Customized gateway examples• Interested in the details?

WS-PGRADE/gUSE Generic-purpose gateway framework

• Based on Liferay• General purpose• Workflow-oriented gateway framework• Supports the development and execution of

workflow-based applications• Supports the fast development of domain-

specific gateways by a customization technology• Most important design aspect is flexibility

Flexibility in exploiting parallelism

Each job can be a parallel program

– Parallel execution inside a workflow node

– Parallel execution among workflow nodes

Multiple jobs run parallel

– Parameter study execution of the workflow

Multiple instances of the same workflow with different data files

Flexibility of using compute infrastructures

• Flexible management of Security: – Individual users’ certificate (X.509, SAML, pubkey, …)– Robot certificates

• Flexible access to various types of DCIs:• Clusters (PBS, LSF, MOAB, SGE)• Cluster grids (ARC, gLite, GT2, GT4, GT5, UNICORE)• Supercomputers (e.g. via UNICORE)• Desktop grids (BOINC)• Clouds (Direct Access, EGI FedCloud, CloudBroker

Platform)• XSEDE

Flexibility in data storage access• Use Data Avenue Blacktop service

– To access data storages in different DCIs– To transfer files among the storages of different DCIs– To upload/download files to/from the storages of different

DCIs• Data Avenue Liferay portlet to access the data transfer

services of Data Avenue Blacktop• See details: https://data-avenue.eu/• Currently supported protocols:

– HTTP(s), SFTP, GSIFTP, SRM, iRODS, S3

The Data Avenue Blacktop services are available not only by the Data Avenue portlet but also by the nodes

of a WS-PGRADE workflow

Generic data transfer among WS-PGRADE workflow nodes

Data Avenue in WS-PGRADE/gUSE

• Data sources and destinations of jobs can be selected• gUSE automatically manages data transfers using

Blacktop• Actual transfer delegated up to the worker node

wherever possible, bypassing the Blacktop service if the middleware is capable of handling the protocol

Flexibility of gateway types and user views

1. Generic purpose gateways (workflow view)– Core WS-PGRADE/gUSE (e.g. Greek NGI)

2. Generic purpose gateway for specific technologies (workflow view)– SHIWA gateway for workflow sharing and interoperation

3. Domain-specific science gateway instance – Autodock gateway (end-user view)– Swiss proteomics portal (customized GUI using ASM API)– VisIVO Mobile (use of Remote API)

WS-PGRADE/gUSE customization possibilities

• Application Specific Module: ASM API• Remote API• End User View• Job submission
