This PR fixes some warnings by GCC 12.3 about integer type mismatches. Note that we have a bit of a mess between `int` (e.g., `MPIManager::num_processes_`) and `size_t` (e.g., return type...

ConnBuilder loop_over_targets() does not work as intended

2

Following Ippen et al (2017, Sec 3.2), ConnBuilders should loop over local nodes instead of over targets when the number of local nodes is smaller than the target population. Unfortunately,...

This issue is based on a [recent post on the NEST User Mailing List](https://www.nest-simulator.org/mailinglist/hyperkitty/list/[email protected]/thread/F2QNSEAAUQP3E6IZADG7U2QU2MEXAQMW/). Thanks to Miriam Kempter for reporting it! A minimal reproducer with two different cases triggering errors...

Connecting nodes with spatial positions fails in corner case

1

In NEST master (355e52d121ff) `Connect()` fails in the following situation ```python l = nest.Create('parrot_neuron', n=20, positions=nest.spatial.free(pos=[(j+1, 0) for j in range(20)], edge_wrap=True)) nest.Connect(l, l, {"rule": "pairwise_bernoulli", "p": 1.0, "mask": {"circular":...

This PR makes sure that columns format nicely even if phase name become longer. Also switches to format strings.

Allow use of pairwise_bernoulli rule for connections to devices

1

#560 prohibited the use of probabilistic connection rules when connecting to devices to address #351. This rule is overly restrictive: Only connection rules that have a global constraint, such as...

Xcode instructions are outdated

1

Instructions for how to develop NEST with Xcode are badly outdated, especially wrt MPI versions and MacPorts.

Properly control validity of NodeCollections and SynapseCollections with hashes

1

`NodeCollection`s and `SynapseCollection`s remain existent in Python even after a `ResetKernel()`. We currently protect against failing C++ assertions on `set()`/`get()` on `SynapseCollection` by checking against an empty network, but that...

Refactor handling of timers to achieve simpler code in place of use and increase coverage

1

Currently, timers in NEST are typically started/stopped with code like this: ```c++ if ( tid == 0 ) { sw_communicate_prepare_.start(); } ``` or ```c++ #ifdef TIMER_DETAILED if ( tid ==...

aeif-model documentation does not point out peculiarities

1

The current documentation for the aeif models does not point out two peculiarities of these models: 1. The default refractory period to these models is *zero*. This is consistent with...
