11 * Batch mode (accessing these Jupyter notebooks requires to log in with an EBRAINS account. For your own experiments you will also need an own collab + test quota. Please see the [[getting access page>>doc:Collabs.neuromorphic.Getting access.WebHome]] for the how-to. The [[dashboard page>>https://nmpi.hbpneuromorphic.eu/dashboard/]] shows the system queue status and usage)
12 ** Example: [[synfire chain>>https://lab.ebrains.eu/user-redirect/lab/tree/shared/NMC%20Collab%20copy%20template/BrainScaleS/BrainScaleS_01_Chain.ipynb]] on BrainScaleS-1 wafer scale system
13 ** Example: [[single membrane experiments>>https://lab.ebrains.eu/user-redirect/lab/tree/shared/NMC%20Collab%20copy%20template/BrainScaleS/BSS-2_singleNeuron.ipynb]] on BrainScaleS-2 single chip system
14 * Interactive mode: since November 2021 it is possible to use the BrainScaleS-2 single chip system also interactively from the EBRAINS collab (please use the "EBRAINS_release_..." kernel for running interactive scripts. See the "BrainScaleS-2 interactive demo does not work with error message "ModuleNotFoundError: No module named 'pynn_brainscales'"" entry on the troubleshooting page for a description how to select the kernel)
15 BrainScaleS-2 interactive examples are [[documented here>>https://electronicvisions.github.io/documentation-brainscales2/brainscales2-demos/0-welcome.html]] and the latest version can be downloaded from the [[Jupyter notebook branch in this github repository>>https://github.com/electronicvisions/brainscales2-demos/tree/jupyter-notebooks]] (use the "Raw" button at the file you want to download) or [[git clone the whole examples part>>doc:Collabs.neuromorphic.HowToUse.Git clone from a notebook.WebHome]].

17 * Via direct access: we can also provide direct ssh access to the system control servers. Please request this type of access via support@ebrains.eu

21 For BrainScaleS three different system types are currently available via the EBRAINS Collaboratory ("Collab"):
22
23 * BrainScaleS-2: the 2nd generation system. Currently available are single chip systems, accessible via Collab since June 2020 for low-level access and since March 2021 also for access using PyNN.
24 For a system introduction / overview and some experiment examples see e.g. "[[The BrainScaleS-2 accelerated neuromorphic system with hybrid plasticity>>https://arxiv.org/abs/2201.11063]]." (arXiv, published 26 January 2022)
