Real-time interaction is a necessary part of the modern high performance computing (HPC) environment, used for tasks such as development, debugging, visualization, and experimentation. However, HPC systems are remote by nature, and current solutions for remote user interaction generally rely on remote desktop software or bespoke client-server implementations combined with an existing user interface. This can be an inhibiting factor for a domain scientist looking to incorporate simple remote interaction to their research software. Furthermore, there are very few solutions that allow the user to interact via the web, which is fast becoming a crucial platform for accessible scientific HPC software. To address this, we present a framework to support remote interaction with HPC software through web-based technologies. This lightweight framework is intended to allow HPC developers to expose remote procedure calls and data streaming to application users through a web browser, and allow real-time interaction with the application while executing on a HPC system. We present a classification scheme for remote applications, detail our framework, and present an example use case within a HPC visualization application and real world performance for remote interaction with a HPC system over a Wide Area Network.
