Table 1.
CPU time and maximum memory for each simulator
| Simulator | CPU time (s) | Maximum memory (Gb) |
|---|---|---|
| PBSIM | 5 | 0.2 |
| PBSIM2 (this work) | 7 | 0.2 |
| LongISLND | 565 | 26.7 |
| NPBSS | 1024 | 0.1 |
| DeepSimulator1.5 | 113 344 | 15.3 |
| PaSS | 14 | 0.8 |
| Badread | 1498 | 3.5 |
Note: CPU time and maximum memory usage were measured for generating a total of 100 Mb of reads. NPBSS was executed on a Windows system equipped with Intel(R) Core(TM) CPU(i7-8565U@1.80 GHz). The others were executed on the National Institute of Genetics supercomputer system. The execution of DeepSimulator1.5 included basecalling by Guppy and assessing read accuracy by Minimap2; when using ‘-c 8’ option (CPU number), wall-clock time was 20 662 s.
