  1. WS-PGRADE/gUSESupporting e-Science communities in Europe Zoltan Farkas MTA SZTAKI LPDS, Hungary

  2. 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?

  3. 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

  4. Parallel execution inside a workflow node • Parallel execution among workflow nodes Multiple jobs run parallel Each job can be a parallel program Flexibility in exploiting parallelism Multiple instances of the same workflow with different data files • Parameter study execution of the workflow

  5. 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

  6. 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: • Currently supported protocols: • HTTP(s), SFTP, GSIFTP, SRM, iRODS, S3

  7. FS1 FS2 FS3 FSn Data Avenue services Data Avenue @ XY Data Avenue Portlet DataAvenue @ SZTAKI WS-PGRADE gateway Data Avenue Blacktop service Amazon Openstack gLite GT5

  8. FS2 FS5 FS1 FS3 Generic data transfer among WS-PGRADE workflow nodes DCI1 DCI2 WS-PGRADE Workflow J1 J3 J2 J4 J5 The Data Avenue Blacktop services are available not only by the Data Avenue portlet but also by the nodes of a WS-PGRADE workflow J: Job FS: File storage system, e.g. gsiftp, iRODS, SRM

  9. 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

  10. Flexibility of gateway types and user views • Generic purpose gateways (workflow view) • Core WS-PGRADE/gUSE (e.g. Greek NGI) • Generic purpose gateway for specific technologies (workflow view) • SHIWA gateway for workflow sharing and interoperation • Domain-specific science gateway instance • Autodock gateway (end-user view) • Swiss proteomics portal (customized GUI using ASM API) • VisIVO Mobile (use of Remote API)

  11. WS-PGRADE/gUSE customization possibilities • Application Specific Module: ASM API • Remote API • End User View • Job submission

  12. Some examples of SCI-BUS domain-specific gateways

  13. VisIVO Astrophysics Science Gateway Architecture
