Table 5. Benchmarks for different grid sizes using NFTsim v.0.1.5.
| Nodes | Storage [GB] | Memory [MB] | Runtime Gno [s] | Runtime Gwo [s] |
|---|---|---|---|---|
| 144 | 1.1 | 5 | 24 | 44 |
| 256 | 1.9 | 6 | 40 | 79 |
| 1024 | 7.3 | 16 | 161 | 302 |

The value of Nodes is reported on the first column. The second column informs the storage size of the output file with all the model variables for each node (firing rate, voltages, fields, coupling strengths) sampled at 1/Δtout = 512 Hz for the group of simulations Gwo. The third column presents the total memory usage of the process. Reported runtimes on the fourth column and fifth columns are the time elapsed in seconds. The values on the fourth column correspond to simulations with no output (no) written to the output file. The fifth column corresponds to the running times of simulations for which all the model variables for every node of the grid are written to the output file (wo). The same corticothalamic model is used in every simulation with Tsim = 16 s, and Δt = 2−14 s.
