The IEEE NPSS works with several different conference software products. All of them have the full functionality for a conference. The capability of the software may differ depending on the size of the conference. The tasks that need to be handled for a conference are:

For small and medium-size conferences the tool: “Indico” is very useful. For larger conferences, a new software tool, “Contxt/Eventclass,” is now in use (such as for NSS/MIC). A new tool is “ExOrdo” which is under test for the ICOPS21 and PPC21 conferences.

In general:


  • Maintained at CERN and heavily used in high energy physics community
  • Main features for conference easy to use included: abstracts, agenda, upload of talks, roles
  • Statistics of conference
  • Slide repository to cache files online and offline
  • Software free of charge for implemented features
  • New features discussed with Indico team at CERN and will be included
  • Mobile App (3rd party 150 Euro)
  • Contact person: Martin Grossmann

An example of use can be seen on the webpage of the Real time conference.
