In the past few years, we have developed a web-based graphical user interface (GUI) for the NEST simulation code: NEST Desktop . This GUI enables the rapid construction, parametrization, and instrumentation of neuronal network models typically used in computational neuroscience. The primary objective was to create a tool of classroom strength that allows users to rapidly explore neuroscience concepts without the need to learn a simulator control language at the same time.
Currently, NEST Desktop requires a full NEST installation on the user’s machine, limiting uptake by a non-expert audience, and limiting the networks studied to such that can be simulated on a laptop or desktop machine. To ease the use of the app and the range of simulations possible with NEST Desktop, we want to separate the GUI from the simulation kernel, rendering the GUI in the web browser of the user, while the simulation kernel is running on a centrally maintained server.
NEST Desktop has a high potential to be successful as a widely used GUI for the NEST Simulator. To achieve this goal, in a first step all tools have to agree on a communication scheme and data format (using JSON) used to interact with a server-side running NEST instance in a session management, e.g. Docker or Singularity containers. Next, previously developed tools, namely the NEST Instrumentation App  and VIOLA , will be integrated as a plugin into the app to extend visual modeling and analysis functionalities. In the course of this work, the use of an in situ pipeline  developed for neuronal network simulators will be considered to also enable the app to receive larger data sets from NEST during a running simulation, enhancing the interactivity of the app also for large simulations on HPC facilities.
We plan to develop and maintain NEST desktop sustainably. Therefore, we intend to integrate NEST desktop into the HBP infrastructure. Additionally, the open-source code of NEST Desktop will be published as a standalone distribution for teaching and training.
