abstract = {NEST is a simulator for spiking neuronal networks that
commits to a general purpose approach: It allows for high
flexibility in the design of network models, and its
applications range from small-scale simulations on laptops
to brain-scale simulations on supercomputers. Hence,
developers need to test their code for various use cases and
ensure that changes to code do not impair scalability.
However, running a full set of benchmarks on a supercomputer
takes up precious compute-time resources and can entail long
queuing times. Here, we present the NEST dry-run mode, which
enables comprehensive dynamic code analysis without
requiring access to high-performance computing facilities. A
dry-run simulation is carried out by a single process, which
performs all simulation steps except communication as if it
was part of a parallel environment with many processes. We
show that measurements of memory usage and runtime of
neuronal network simulations closely match the corresponding
dry-run data. Furthermore, we demonstrate the successful
application of the dry-run mode in the areas of profiling
and performance modeling.},
