The routine use of electronic structures in many chemical simulation applications calls for
efficient and easy ways to access electronic structure programs. We describe how the
graphics processing unit (GPU) accelerated electronic structure program TeraChem can be
set up as an electronic structure server, to be easily accessed by third-party client programs.
We exploit Google's protocol buffer framework for data serialization and communication. The
client interface, called TeraChem protocol buffers (TCPB), has been designed for ease of …
