Getting Triton help¶
There are many ways to get help, and you should try them all. If you are just looking for the most important link, it is our issue tracker.
Whatever you do, these guidelines for making good support requests are very useful.
The Triton docs¶
In case you got to this page directly, you are now on the Triton and Science-IT (CS, NBE, PHYS at least) documentation site. See the main page for the index.
Science is a collaborative process, even if it doesn’t seem so. Academic courses don’t teach you everything you need to know, so it’s worth trying to work together and learn from each other - your group is the expert in it’s work, after all.
We keep track of cluster issues at https://version.aalto.fi/gitlab/AaltoScienceIT/triton/issues. Feel free to post your issue there. Either admins or other users can reply — and you should feel free to reply and help others, too. The system is accessible from anywhere in the world, but you need to login with HAKA (using the button). All newly created issues are reported to admins by email.
This is primary support channel and meant for general issues like general help, troubleshooting, problems with code, new software requests, problems that may affect several users.
If you get a message that you are blocked from version.aalto.fi, send the email to servicedesk. It’s not your fault: it automatically blocks people when their organizational unit changes. Yes, this is bad but it’s not in our control…
Email ticketing system¶
For private issues you can also contact us via our email alias (available from our Wiki page - login required). This is primarily intended for specific issues such as requesting new accounts, quotas, etc. Please avoid sending personal mails directly to admins, because it is best for all admins to be aware of issues, people may be absent, and personal emails are likely to be lost.
Most general issues should be reported to the issue tracker instead, not by email. Email is primarily for accounts related queries.
Users’ mailing list¶
All cluster users are on the triton-users mailing list (automagically kept in sync with those who have Triton access). It is for announcements and open discussions mainly, for problem solving please try the tracker.
If you do not receive list emails, you’d better check out with your local Triton admin that you are on the list. Otherwise you miss all the announcements including critical ones about maintenance breaks.
Come by one of the Scientific computing garages any week. It’s the best place to get problems solved fast.
You can also come and talk to us face-to-face, but of course we have to be in-office. This is especially useful when there is an open-ended question where we have to discuss what is the best solution. We may then ask you to open a ticket once there is an answer, so that we can track the progress and not forget.
Triton support team¶
Most of us are members of your department’s support teams, so can answer questions about balancing use of Triton and your department’s computers. We also like it when people drop by and talk with us, so that we can better plan our services. In general, don’t mail us directly - use either the issue tracker above or the support email address. You can address your request to a specific person.

We have regular training in topics relevant to HPC and scientific computing. In particular, each January and June we have a “kickstart” course which teaches you everything you need to know to do HPC work. Each Triton user should come to one of these. For the schedule, see our training page.
Getting a detailed bug report with triton-record-environment¶
We have a script named
triton-record-environment which will record
key environment variables, input, and output. This greatly helps in
To use it to run a single command that gives an error:
triton-record-environment YOUR_COMMAND Saving output to record-environment.out.txt ...
Then, just check the output of
shouldn’t have any confidential information, but make sure) and send
it to us/attach it to the bug report.
If you use Python, add the
-p option, matlab should use
and graphical programs should use
-x (these options have to go
before the command you execute).
