The OnlineHPC is a free public web service that supplies tools to deal with high performance computers and online workflow editor. OnlineHPC allows users to design and execute workflows using the online workflow designer and to work with high performance computers – clusters and clouds. Access to high performance resources is available as directly from the service user interface, as from workflow components. The workflow engine of the OnlineHPC service is Taverna which is traditionally used for scientific workflow execution in such domains, as bioinformatics,[1][2] cheminformatics,[3] medicine, astronomy,[4] social science, music, and digital preservation.[5]

History

OnlineHPC was started at the Institute for Information Transmission Problems in 2012 as a project for the institute’s researchers whose work need access to computer clusters and who are not professional programmers.

The project motivation is that there is a gap between researcher skills and competence level needed to run high performance computing. There are at least three barriers on the way to HPC:

The last requirement stops majority of even the stoutest researchers that passed first two levels. The service aims to reduce the barriers by providing a complete pre-configured set of tools required for work with computer clusters: in-browser terminal emulator, files system browser, credentials manager and massive task tool.

After a while it became obvious that engineering and scientific tasks require more elaborate tool suit that enables researchers to execute flow of tasks – workflows. Unless there is a number of scientific workflow implementations, they are almost all desktop applications and thus the aim was creating an online environment with a focus on simplicity and enhanced user experience.

For now the project is in use in bioinformatics,[6][7] human health,[8] telecommunications and other domains.

Capabilities

OnlineHPC has a workflow designer available online using major browsers (Firefox, Chrome and Internet Explorer) on desktops and tablets.

Workflows may include components for:

The service also has basic tools to prepare and run massive computational tasks on clusters - in-browser terminal emulator, file system browser and cluster status viewer. User may choose to operate existing hardware cluster or to start a configure a new cluster instance in the cloud.
