Abstract
SciFloware is a middleware for the execution of scientific workflows in adistributed and parallel way. It capitalizes on our experience with the Shared-Data Overlay Network and aninnovative algebraic approach to the management of scientific workflows. SciFloware provides a developmentenvironment and a runtime environment for scientific workflows, interoperable with existing systems. Wevalidate SciFloware with workflows for analyzing biological data provided by our partners CIRAD, INRAand IRD.
