Large scale experimentations on models
Methods
Design of experiments on a space of parameters. |
 |
Calibration. |
 |
Methods
Genetic algorithms. |
 |
 |
Sensitivity analysis. |
Naturally parallel algorithms => leverage parallelism.
What does OpenMOLE do ?
It implements exploration algorithms. |
 |
It transparently delegates computational loads to massively parallel environments. |
 |
Upscaling
Prototype small
Experiment large
A naturally parallel formalism to design experiments.
