Distributed In-memory Data Management for Workflow Executions

Autor: Souza, Renan, Silva, Vítor, Lima, Alexandre A. B., de Oliveira, Daniel, Valduriez, Patrick, Mattoso, Marta

Complex scientific experiments from various domains are typically modeled as workflows and executed on large-scale machines using a Parallel Workflow Management System (WMS). Since such executions usually last for hours or days, some WMSs provide use

Scientific workflow management systems (SWfMS) are powerful tools in the automation of scientific experiments. Several workflow executions are necessary to accomplish one scientific experiment. Data provenance, typically collected by SWfMS during wor

International audience; Distributed Hash Tables (DHTs) provide an efficient solution for data location and lookup in large-scale P2P systems. However, it is up to the applications to deal with the availability of the data they store in the DHT, e.g.
