- Have included HPC cluster name in Zoom username,
e.g.
[Dardel] Sven Svensson
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?
The multiple ways to connect to your HPC cluster¶
You have an account at an HPC cluster (a prerequisite for this course) and you want to connect to your HPC cluster.
There are multiple ways to do so!
Here is an overview of the ways to login in this course:
| Feature | Desktop environment using a web browser | Console environment | Desktop environment using a remote desktop client |
|---|---|---|---|

| Environment | Desktop environment | Console environment | Desktop environment |
| Summary | Familiar to most | Less familiar to most | Familiar to most |
| Type of user interface | Graphical | Terminal | Graphical |
| Installation needed? | Unlikely | Likely | Most likely |
| Program used | A web browser | An SSH agent | A remote desktop client |
| Example programs | Firefox, Chromium, Chrome, Edge, Safari | Terminal, MobaXterm | ThinLinc, Remmina, krdp |
| Works on which clusters? | All except Dardel and Tetralith | All | All, except Bianca |
| Course session | Session | Session | Session |
Exercises¶
Exercise 1: rename yourself¶
Please change your Zoom name to start with your HPC cluster,
as [name_of_hpc_cluster] your_name, e.g. [Dardel] Sven Svensson.
Why the name of the HPC cluster first?
It will make Zoom sort your names in a way most convenient for the course, which helps the logistics of the course.
Exercise 2: be assigned a Zoom room¶
We will use breakout rooms, as this is best for interaction and learning. However, some prefer to work alone. In this course, we allow for both.
For a quick process, we follow the following procedure:
flowchart TD
prefer_work_alone(Prefer to work alone?)
raise_hand_in_round_1[Raise your hand in the first round]
wait_until_after_round_1[Wait until after the first round]
prefer_work_alone --> |Yes| raise_hand_in_round_1
prefer_work_alone --> |No| wait_until_after_round_1In your breakout rooms, start with the next exercise.
Good luck and enjoy!
Exercise 3: find your first way to login¶
Not all HPC clusters can do all ways to login.
Below an overview of the sessions and their relations.
flowchart TD
use_dardel_or_tetralith(Use Dardel or Tetralith?)
use_bianca(Use Bianca?)
account[Account for HPC cluster]
login_desktop_website_no[Login to desktop environment from a website]
login_console_no[Login to console environment]
login_desktop_tool_no[Optional: login to desktop environment using a remote desktop client]
login_console_yes[Login to console environment]
login_desktop_tool_yes[Login to desktop environment using remote desktop client]
account --> use_dardel_or_tetralith
use_dardel_or_tetralith--> |No| login_desktop_website_no
login_desktop_website_no --> login_console_no
login_console_no --> use_bianca
use_bianca --> |No| login_desktop_tool_no
use_dardel_or_tetralith--> |Yes| login_desktop_tool_yes
login_desktop_tool_yes --> login_console_yesDecision tree to find out which sessions to follow in which order. The same information is shown in the table below.
Done?
Then it is time to start your first file transfer :-) !
