DIstributed Computing Environments (DICE) Team
We are a group of computer scientists and IT experts from the Department of Computer Science AGH and ACC Cyfronet AGH. We are a curiosity- and research-driven team, specializing in large-scale distributed computing, HPC, Web and Cloud technologies. We develop new methods, tools and environments and we apply these solutions in e-Science, healthcare and industrial domains.

HyperFlow

HypeFlow_logo.pngHyperFlow is a lightweight tool that enables orchestration of scientific applications into complex pipelines, or scientific workflows. HyperFlow aids users in composing their applications into workflows, deploying them in the cloud, and executing them. A workflow in HyperFlow is described as a graph of workflow activities (called processes) using a simple JSON-based data structure. The activities can either be implemented in JavaScript or mapped to executable programs. In the latter case, the workflow developer only needs to associate each workflow activity with a previously prepared Virtual Machine image where appropriate programs are installed. This approach makes HyperFlow equally suitable for experienced programmers who desire low-level programming capabilities, and domain specialists who only wish to construct pipelines out of existing module. HyperFlow also automates workflow deployment and execution in the cloud. More information about HyperFlow including its source code and manuals can be found at https://github.com/dice-cyfronet/hyperflow.
