Introduction 'Connect'

Learning outcomes

  • Can find an overview of the course

For teachers

Teaching goals are:

  • Learners can find an overview of the course
  • Learners can find the schedule
  • Learners have seen the ways to connect at this course
  • Learners have seen where to put anonymous feedback during the day
  • Learners have included their HPC cluster name in Zoom username

Prior questions:

  • What is a file tranfer?
  • What does one need to do, to be able to do a file transfer?
  • How does it look like to do a file transfer?
  • Can you name some programs that can do file transfer?

Exercises

Exercise 0: rename yourself

Please change your Zoom name to start with your HPC cluster, e.g. Sven [Rackham]. Put your name first: it is the more important information here :-)

Exercise 1: remember a Zoom room

We will use breakout rooms, as this is best for learning. Ideally, each breakout room has 2 learners for the same HPC cluster.

HPC cluster name Main breakout room
Alvis Room 1
Bianca Room 2
COSMOS Room 3
Dardel Room 4
Kebnekaise Room 5
Tetralith 1 Room 6
Tetralith 2 Room 7
Tetralith 3 Room 8
Vera Room 9
Other 1 Room 10
Other 2 Room 11
  • When your first breakout room reaches 4 learners, decide upon 2 to move to the next breakout room. Repeat until the group size is below 4.
  • When you are the only one in your main breakout room, the teachers will let you decide to either work in silence or to join another group. You will be taken care of well :-)
