Supercomputing resources are used in both interactive and batch computing modes. The interactive mode is typically used for software development and testing purposes, or for running various command-line tools that work in a user-guided manner. The batch mode is often used for running a large number of jobs simultaneously or for large-scale runs that do not require interaction with the users. We needed a gateway (a web-portal) that could support both interactive and batch computing modes. The interactive mode was required for using a command-line tool for code parallelization through a web browser, and the batch mode was required for compiling and running the programs parallelized using the tool on the production systems at open-science data centers. We are iteratively developing this gateway, and its current version is live at https://ipt.tacc.cloud. An overview of the design and implementation of this gateway is presented in this paper. With minimal modifications, the architecture of this gateway can be reused for supporting other similar projects.
