The aim of the workshop is to share knowledge about high-performance geocomputing. The morning session will concentrate on CSC Taito supercluster. First CSC computing resources are presented in general, and as example use case we will do a hands-on exercise using Python with DEM data.

In the afternoon different current geocomputing projects in Finland are presented. The day will end with an open discussion related to the topic.

Morning session:

• CSC computing resources for spatial analysis
• Zonal statistics exercise with Python in Taito. Materials.

Remote participation

It is possible to participate in the seminar also via teleconference with some limitations:

• The Taito hands-on exercise can be done only if you have your own account to Taito. University users and research insitute users can make themselves an account here.
• The seminar room is quite big, so it is possible that comments from last rows are difficult to hear.

Link to the teleconference room: https://cscfi.zoom.us/j/182498570

We use Zoom meeting rooms for the seminar. At the first time, Zoom asks you to download a launcher plug in. You can do this beforehand. After this, you should be able to open the seminar room from the link. The seminar room is timed, and will open when the seminar begins. When signing in, remember to click "join audio conference by computer". If you are using a headset, it is easiest to plug them in before opening Zoom.
