Benchmarks¶
The following benchmarks represent typical use cases of Mirheo. They were performed on the Piz-Daint supercomputer for both strong and weak scaling. See in benchmarks/cases/ for more informations about the run scripts.
Bulk Solvent¶
Periodic Poiseuille flow in a periodic domain in every direction, with solvent only.
Timings are based on the average time-step wall time, measured from the createStats
plugin.
The weak scaling efficiency is very close to 1 thanks to the almost perfect overlapping of communication and computation.
Bulk Blood¶
Periodic Poiseuille flow for blood with 45% Hematocrite in a periodic domain in every direction.
Timings are based on the average time-step wall time, measured from the createStats
plugin.
The weak scaling efficiency is lower than in the solvent only case because of the complexity of the problem:
- Multiple solvents
- FSI interactions
- contact interactions
- Many objects
- Bounce back on membranes
The above induces a lot more communication than the simple solvent only case.
Poiseuille Flow¶
Poiseuille flow between two plates (walls), with solvent only.
Timings are based on the average time-step wall time, measured from the createStats
plugin.
Rigid Objects suspension¶
Periodic Poiseuille flow for rigid suspensions in a periodic domain.
Timings are based on the average time-step wall time, measured from the createStats
plugin.
I/O overlap with computation¶
Data dump every 100 steps for the periodic Poiseuille flow benchmark.
Computation timings are based on the average time-step wall time, measured from the createStats
plugin when no I/O is performed.
The I/O timings are extracted from the log files.
The total timings are based on the average time-step wall time when I/O is active.
