HPC Community Cloud is a software system for aggregation of computing resources into a single entry service and provisioning of access to these resources for users through web-application and for external software systems through application programming interface. HPC Community Cloud encapsulates peculiarities of access to different computing systems, allows users to accumulate and share content such as applications, data and documents. The paper presents the architecture and prototype implementation of the HPC Community Cloud.
