In my previous post I described a GPU implementation of Smoldyn. In this post I'm going to describe a Web-Service that provides an internet access to it. Using this service a user can start a simulation just uploading a configuration file describing a model. The service executes this file and uploads screenshots and other output files to user's profile, so a user can access them. This allows users, who doesn't have access to high performance GPUs enjoy all benefits of GPU implementation (200x speedup for instance).
