The workshop aims to discuss the use of High-Performance Computing (HPC) to support monitoring the world for any nuclear explosions on the ground, in the ocean and in the atmosphere.

Participants Profile:

The target audience for the workshop will consist of scientists, engineers, and other persons with expertise in High‑Performance Computing, Machine Learning, and Seismic, Hydroacoustic, Infrasound, Atmospheric Transport, and radionuclide simulation and data analysis.

Please be informed that the Provisional Technical Secretariat (PTS) solicits presentations and posters from participants on the topics of the Workshop for travel funding applications.

Financial Information

Financial support may be available to a limited number of participants. Such assistance must be requested at the time of registration (by selecting the relevant box during online registration) and no later than 1 March 2023.

Financial support will be considered only for those who have submitted an abstract which will be accepted. Participants are strongly encouraged to first seek travel and participation funds from non-CTBTO sources.

In accordance with the Staff regulations and rules and Administrative Directives, the PTS will provide to funded participants the following:

  • A Daily Subsistence Allowance (DSA) that is sufficient to cover the related expenses during the workshop program will be granted to funded participants;
  • The PTS travel agent will reserve, issue and forward the flight ticket to the participants for the most direct and economic route;
  • Funded participants are not allowed to purchase their own tickets unless, under exceptional circumstances, when authorized to do so and only if this proves to be the most cost efficient for the PTS;
  • The PTS will book a hotel and cover the costs of accommodation; and
  • Health insurance for the duration of the workshop.


The International Data Centre is constantly trying to enhance its technical capabilities as experience is gained in the operation of the International Monitoring System (IMS). To this end it will hold the HPC workshop for nuclear explosion monitoring to identify and discuss solutions that will improve seismic, hydroacoustic, infrasound, and radionuclide modelling and data analysis, atmospheric transport modelling and other needs of the CTBTO. The workshop includes but is not limited to the following topics:

  • Numerical modelling applied to seismic, hydroacoustic, infrasound, atmospheric transport, and radionuclide simulations;
  • Deep learning and machine learning applied to data analysis, the accuracy of event locations and characterization of uncertainty, data fusion, and physics-informed networks.

Other Pertinent Information

  • Visas: All participants should apply for visas, if needed, at the corresponding consular office upon receipt of an acceptance letter from the Secretariat, in order to ensure timely processing.
  • Health/Accident Insurance: It is strongly recommended that prior to departure all non-funded participants should acquire health and accident insurance for the duration of the workshop.
