User-oriented partial result evaluation in workflow-based science gateways

Content Provider ACM Digital Library
Author Olabarriaga, Silvia D. Ramezani, Sara Jaghoori, Mohammad Mahdi
Abstract Scientific workflow management systems provide a useful layer for defining and executing applications supported by science gateways. In various optimization or simulation applications that need to run for a long time, the users may be satisfied with an incomplete execution. The system should, therefore, allow users to evaluate partial results of the workflow execution. This entails performing a consolidation step, that would normally run only at the end of the workflow. In this paper, we present two new workflow patterns that formally define how the consolidation step should be executed (on partial inputs) whenever the user pro-actively requests evaluation of the partial results. This changes the traditional workflow behavior, in which every step runs once, when all its data dependencies are satisfied. We evaluate implementing these patterns in various workflow management systems and finally present a DIRAC-based implementation of this feature for the use case of a molecular docking gateway.

About National Digital Library of India (NDLI)
NDLI logo

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
