Three forms of access are available:

Test access
Only a brief abstract is required explaining why you wish to use the platform. It is not necessary to fill in the "Project description" field. No previous experience with the platform is required. A fixed quota of 5000 core-hours (for the SpiNNaker system) and/or 0.1 wafer-hours (for the BrainScaleS system) will be allocated, together with temporary storage of 1 GB.
Preparatory access
Only a short technical motivation is required. Previous experience with the platform (through a test access) is expected. A fixed quota of 500000 core-hours (for the SpiNNaker system) and/or 10 wafer-hours (for the BrainScaleS system) will be allocated, subject to a brief technical review, together with temporary storage of 10 GB.
Project access
For projects requiring more than the test/preparatory quotas, a scientific motivation of about one page should be provided, and a request for resources (in core-hours, wafer-hours and/or GB of storage) should be specified, and justified with respect to the project's scientific goals. This proposal will receive both scientific and technical reviews.

Do not forget to specify which type of access you are requesting, and which of the Neuromorphic Computing Systems ("BrainScaleS", "Spikey" and/or "SpiNNaker") you wish to use.

Access is granted on a per-collab basis, not per-person. All members of this collab will be able to make use of the quota.
