In Situ Analysis and Visualization with SENSEI (2-days) & Advanced Visualization Techniques (1-day)

The Swiss National Supercomputing Centre is pleased to announce the two-day workshopIn Situ Analysis and Visualization with SENSEI,” followed by the one-day workshopAdvanced Visualization Techniques“. The two events will take place from March 21-23, 2018 at CSCS in Lugano, Switzerland.

Interested participants may decide whether registering for both events or exclusively for one of them.


In Situ Analysis and Visualization with SENSEI (two days) (March 21-22, 2018)

Extreme-scale computer simulations are faced with a constantly widening gap between computational and I/O rates; one alternative to overcome this challenge is based on the idea of in situ processing, where visualization and analysis processing is performed while data is still resident in memory. The SENSEI in situ Data Interface is an API that promotes code portability and reusability. From the simulation view, a developer can instrument their code with the SENSEI API and then make use of any number of in situ infrastructures, such as ADIOS, ParaView Catalyst, GLEAN and VisIt Libsim. This tutorial presents the fundamentals of in situ data analysis and visualization leveraging this generic interface. Attendees will learn the basics of in situ analysis and visualization while being exposed to advanced analysis such as time-dependent autocorrelation and interactive monitoring and steering. We demonstrate the infrastructure coupling of mini-apps using ADIOS, ParaView Catalyst, and VisIt Libsim.


Advanced Visualization Techniques (, (one day) (March 23, 2018)

VTK is a software system for 3D computer graphics, image processing and visualization with world-class usage. We will demonstrate many of the recent additions to the toolkit, covering interactive ray-tracing and photo-realistic renderings, volume rendering, parallel processing, visualization in a Web browser, Qt5-based mini-apps. In concert with the upcoming release of ParaView 5.5, we will put in practice many of the new features in this release with special tuning for the Piz Daint hardware. All demonstrations will be driven by Python scripts to encourage re-use for the participants’ own simulations results.


Introductory-level usage of ParaView or VTK.



The agenda will follow closer to the meeting dates.


All participants must register for the above mentioned events (separately or to both of them). The registration fee includes coffee breaks and lunches throughout the three day course.

Further information on the workshop, including information on registration are available on the event page.

Course Fees:

  •  In Situ Analysis and Visualization with SENSEI & Advanced Visualization Techniques: CHF 240
