Summer is beginning for real now, and we know that the Triton cluster is still important for research. We have some support availability over the summer, and will keep an eye on the cluster too. See our email/help channels for more detail on summer support.
We are beginning day 2 of our course (see thread^):
- What is a cluster and what is the queuing system?
- Basics of running jobs (nice and slow: basic interactive, batch jobs, monitoring, to prepare for more complex stuff tomorrow)
- A quick survey of applications and data on the cluster
- A long Q&A.
There is a disruption in the broadcaster's internet connection. Hopefully we are back by 15:00 EEST when we should resume.
We are live! Currently the Intro to #SciComp that talks about resources needed for computing. Check out this behind the scenes view...
Update: The course starts today at 11:00 CEST and 12:00 EEST. I got the CEST time conversion wrong...
#SciComp / #HPC Kickstart day 1 is for a broad audience. (livestream starting today at 12:00, times in EEST):
- 11:50: icebreakers
- 12:00 intro
- 12:10: From data storage to your science
- 12:25: Computational reproducibility and open science
- 13:00: Interview, "Humans of SciComp"
- 13:25: What can you do with a cluster?
- 14:00: Connecting to a cluster
- 15:00: How to ask for help with (super)computers
- 15:25: VS Code on HPC

Our #SciComp / #HPC kickstart course starts tomorrow at 12:00 EEST / 11:00 CEST. It is livestream, so anyone can watch with no questions asked. Register for the Q&A document, even if you aren't at #AaltoUniversity (and we teach so that it's useful to others too).
Day 1: basic background and examples. Day 2-3: Using a cluster.

#ScientificComputing #teaching
Note to users: The older version of the Triton HPC cluster will be unavailable on 9:00 30.may. See email or Triton issue 1593 for more info.
How the livestream courses work:
- We have livestream with co-teaching and demos
- There is a "Notes doc" for async and anonymous questions. We have experts answering through the whole course, both basic and advance questions are welcome
- There are "exercise breaks" where stream is muted and people work locally on what we just did. You can use the time to help your local attendees.
We do comment on differences between clusters. You are welcome to help us organize the course too. #HPC
Our "#HPC Summer Kickstart" course is 4-6 June 2024 (EU afternoons). Everyone is invited: it's #livestream so yes, *you* can attend.
- Day 1: general #SciComp concepts and practices
- Day 2-3: Running stuff on a cluster (Slurm, batch jobs, interactive, parallel, etc).
It's a first course that everyone should be able to follow. You can re-advertise to your colleagues and be their local guide to your own cluster.

Triton cluster jobs will be suspended at 9:00 on Wednesday (2024 May 15) for maintenance. After it is over, please verify all jobs are OK. This is to avoid having to reserve all nodes and stop all calculations, which we would normally do. See Triton issue tracker /email for details.
Migration to the new cluster has gone OK: we've worked out most of big UI things, so we are back to daily garage only between 13-14. There are plenty of ongoing software installation issues; for these please make a Triton issue in Gitlab so it can be properly tracked. We remain available by chat.
All-day garage to help with the Triton cluster update continues today (Wed, May 8). Tomorrow is a holiday and we may not continue on Friday/next week (back to normal one-hour-a-day).
TTT4HPC today was excellent, and we had a great presentation on containers (and one of our best lessons, period): If you've wondered what they are and how to use them for #SciComp / #RSEng on #HPC/desktop, this is the starting point you need.

Tuesday Tools and Techniques for #HPC is now live on #livestream. Today's lesson are about containers on clusters, and lasts about two hours starting from now (with exercises in the afternoon).

All-day SciComp garage continues today to help with migrating to the new Triton (working hours only, and we'll stop if there are not enough visitors). If it's relevant to you, you should have links in your email or know how to find it. #AaltoUniversity
We updated the alias triton.aalto.fi to the new Triton (see email for info).

#AaltoUniversity
More than 99% of the performance of a modern computer comes from parallelism. How to exploit it in practice?
Aalto University course "Programming Parallel Computers" is starting on Monday, with close to 400 students already enrolled! All material freely available online!
https://ppc.cs.aalto.fi
"Tuesday Tools and Techniques for HPC" (with @coderefinery people) is starting: it's not a basic course but more advanced cool stories about how we actually use and think about #HPC clusters. As usual, it's a #livestream so anyone can watch: https://scicomp.aalto.fi/training/scip/kickstart-2024/ (and register for interaction) #teaching #SciComp #RSEng #carpentries #CodeRefinery
AI Day 🇫🇮 is joining forces with #NordicAIMeet this year, Oct. 21-22 at the University of Helsinki. Save the date and submit your scientific abstract by April 30!
