Resource usage

16 samples were used to benchmark MeSS and CAMISIM resources usage.

Samples were create by subsampling 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 20, 40, 80, 160, 320, 640 genomes from a total of 2000 complete bacterial genomes (downloaded with assembly_finder).

Each genome was covered at 1x using art_illumina with CAMISIM's custom MBARC error model.

See this nextflow pipeline to run the benchmark.

CPU time

Warning

To simulate a sample with 2.4G base pairs, using one CPU, CAMISIM takes 32 hours, while MeSS takes 3 hours.

Conclusions

MeSS vs CAMISIM on average:

• 5x more parallel (CPU usage)
• 10x faster using one CPU (CPU time)
• Uses 16.7x less memory (physical RAM)
