With this post we give some general information about the ideal contributor application from our point of view. The recommendations we give here hold for all of the proposed projects, but we will also try to give information specific to the respective projects in the corresponding neurostars threads. For a full list of Brian-related projects, see the end of this post.

It took us a while, but we are very happy to finally announce a new release, Brian 2.5 🎉. This release comes with a large number of bug fixes, various small improvements to the C++ code generation process, new examples and improved documentation, as well as a more powerful “generator syntax” for synapse generation. In particular, it is now possible to generate a fixed number of synapses randomly – either for each pre-synaptic or for each post-synaptic cell. We have also updated our build and testing infrastructure, and now provide binary pip-installable packages for all platforms, including the fancy new Apple hardware. Please let us know if you run into any issues!

We will experiment with running a Brian tutorial online. The first tutorial of this kind will take place on Friday, August 7th 2020 from 2pm-6pm BST (UTC+1, see here for other timezones). Free (but mandatory) registration here. We will run the tutorial as a Zoom meeting – registering with the link will give you the URL (please don’t share so we can avoid zoombombing). We will record the meeting and if everything goes reasonably well, we will upload the videos later.

Our paper on brian2genn was published today. It automatically translates Brian models into a format that can be read by the GPU-enhanced neural network simulator (GeNN) to allow it to run on GPU. Some simulations were 400x faster on GPU compared to a single CPU.
