Attention: Due to an upgrade beginning on Friday, the 22nd August 2025, any new collabs, groups and any changes to teams will not be kept beyond the weekend. User creation will also be disabled during this time. The actual upgrade will take place on Wednesday, 27th August. On that day, any service requiring a Keycloak login will be unavailable for the duration of the upgrade. Thank you for your understanding as we complete this important work.

For the duration of the maintenance period, Collaboration and Group creation features will be temporarily disabled and will return HTTP 503 Service Unavailable errors until further notice.

1 == Getting access to the NMC systems BrainScaleS and SpiNNaker ==
2
3 To use the Neuromorphic computing platform (SpiNNaker and BrainScaleS machines, free of charge for tests and for accepted research projects):
4
5 1. [[Get an EBRAINS account>>https://ebrains.eu/register/]] (free of charge). Use the "Register today" link (near the bottom) on the registration page.
6 1. EITHER:
7 11. Send an email to [[neuromorphic@humanbrainproject.eu>>path:mailto:neuromorphic%40humanbrainproject.eu]] stating your EBRAINS account username
8 11. We will create a Collab for you, free of charge and complete with test quota and a few examples.
9 Only for large 'production runs' another quota request is needed via the "Job Manager" in your collab (upper right hand corner in the JobManager: "Quota").
10 1. OR, if you do not need the copied-in example notebooks or would like to fetch them yourself :
11 11. create a new Collab for yourself:
12 111. go to [[https:~~/~~/wiki.ebrains.eu/>>https://wiki.ebrains.eu/]] and click the "Log-in" link in the upper right hand corner, log in with your new EBRAINS account
13 111. Click the "Collabs" link in the menu bar at the top of the window
14 111. Click the "Create a collab" green button and create a private Collab for yourself. The process re-directs you into the new Collab.
15 111. In your new Collab click the "Lab" link in the left hand menu
16 111. Select any of the "Lab Execution Site" offered, then select the "Official EBRAINS Docker image", click start. (Click "Launch Server", if you get "Server not running")
17 111. This will start a Jupyter Lab session (the "Lab") for you.
18 111. Start a "Terminal" via the icon in the "Launcher window" shown. This opens a terminal in the "/mnt/user/shared/NAME_OF_YOUR_COLLAB/" directory. This is a location on the EBRAINS "Drive". Files stored in this location are stored persistently= will still be there, when you open your Collab again some days later 
19 (Note: If you use "File" > "New" > "Terminal" the opened terminal is in the directory "/opt/app-root/src". This location only exists while the Jupyter ("Lab") session is running and will be gone, when a new Lab session is started. Do not use this location, if you want to keep the files. To change into the persistent directory type "cd /mnt/user/shared/NAME_OF_YOUR_COLLAB" (without the " and the name of your your Collab instead of NAME_OF_YOUR_COLLAB)
20 111. fetch the files you would like to work with.
21 E.g. for the BrainScaleS-2 interactive notebooks use the command in the terminal window: 
22 //git clone https:~/~/github.com/electronicvisions/brainscales2-demos.git ~-~-branch jupyter-notebooks-experimental//
23 The command clones the BrainScaleS interactive notebooks into a directory "brainscales2-demos". This directory appears then in the files list on the left hand side of the window. Double click it to enter the freshly cloned directory with tutorial notebooks.
24 To see an overview, open the "tutorial.ipynb"
25 1. Run your own neuromorphic simulations/emulations interactively via Jupyter notebook (link "LAB" in your Collab) directly in your browser (or via the "Job Manager" link in your new collab) using your own [[PyNN>>url:http://neuralensemble.org/PyNN/]] described network and your own input data
26 1. If anything fails: see the [[getting help page>>url:https://electronicvisions.github.io/hbp-sp9-guidebook/getting_help.html]] in the guidebook or use the [[support@ebrains.eu>>mailto:support@ebrains.eu]] email contact.

30 The service has been created mainly by and during the Human Brain Project (HBP). See the page on [[Neuromorphic computing on the HBP website>>https://www.humanbrainproject.eu/en/silicon-brains/]] for project information and the [[EBRAINS neuromorphic computing service page>>https://ebrains.eu/service/neuromorphic-computing]] for the EBRAINS research infrastructure context.
