Hei,

thank you so much for joining the Snakemake Hackathon today and asking your questions! And thanks also to all our instructors and helpers today :)
Do not worry if you could not join today after all, we might do this again in the future.

If you did join, please give us feedback on this event, either by adding it to the collaborative document(https://siili.rahtiapp.fi/snakemake_hack?view#-This-is-a-pilot-event) or answering this e-mail. It is very important to us, to further develop the materials and format.

All materials will stay available for the foreseeable future: https://coderefinery.github.io/snakemake_hackathon/
The Q&A document will also stay available for a while here: https://siili.rahtiapp.fi/snakemake_hack (but please do not add any new questions, as we might not see them there, use cluster support channels instead)

If you have any questions about running Snakemake on your cluster, please contact the respective support help line:
- CSC: servicedesk@csc.fi or Weekly research support coffees (https://ssl.eventilla.com/usersupportcoffee/EN), Wednesdays at 2 p.m. where you can directly discuss with our specialists!
- LUMI: Contact LUMI user support team: https://lumi-supercomputer.eu/user-support/need-help/
- UPPMAX: Support web interface: https://supr.naiss.se/support/

If you are a Puhti user were affected by the SLURM issues today: We are sorry for the inconvenience. You may contact us via above channels if you encounter any issues later, and we can also agree on a zoom session, if needed.

This event has been brought to you by Geoportti (https://www.geoportti.fi/) , CodeRefinery (https://www.coderefinery.org/) and partners.

Hope to see you again in future events!

Kind regards,
Samantha and Snakemake hackathon team

Participant e-mail draft

To be sent 14.5

Dear all,

thank you for your interest in the Snakemake hackathon.

Joining the event

This event will be fully online in Zoom.

Join Zoom Meeting: https://cscfi.zoom.us/j/61757837253
Meeting ID: 617 5783 7253

Agenda

All times in EEST (Helsinki time):

10-10.30 Supercomputing concept refresher Q&A
10.30-11.30 Intro to Snakemake
11.30-12 Snakemake on HPC (first general, then cluster specific)
12-13 Lunch break
13-15 Hackathon (cluster specific breakoutrooms for CSC Puhti + LUMI, UPPMAX and one general room)

You can join any session of interest to you.
Please note that due to the feedback during registration, we will not have a lecture on supercomputing concepts, but have a Q&A/discussion session about materials provided below in the morning.
The idea for the hackathon part is that you work on your own workflow and ask help from specialists where needed. You can also check out our toy example.

Requirements

  1. Please read this material as HPC concept refresher: https://coderefinery.github.io/TTT4HPC_resource_management/#

    • We have reserved 30 min in the beginning of the course for questions related to this material

  2. For the hands-on hackathon part, you need to be able to run stuff on a cluster:

    • For CSC clusters this means, that you need an account and a project with billing units.
      • If you do not have a project, please send us your CSC username until 20.5 by answering to this email.
    • For UPPMAX clusters this means, that you need an account.
      • You will be added to a course project in the beginning of the hackathon session

Note on support

For participants not using Aalto Triton, CSC Puhti/Mahti, LUMI, ENCCS or UPPMAX clusters, we unfortunately cannot provide cluster specific support.
You may still try it out on your cluster/own laptop and ask about Snakemake related stuff though :)

Interaction during the event

We will use a collaborative document to ask, answer and collect all questions and feedback during the event: https://siili.rahtiapp.fi/snakemake_hack?view

Further information

Please refer to the event page for general information about the event: https://ssl.eventilla.com/snakemake_hack

In case of any questions, please answer to this email.

Looking forward to virtually meet you on 22.5!

Kind regards,
Samantha and the Snakemake hackathon team
