Table 5. Summary of the simulation times for different CRL models, from the most simple one (single lens equivalent) up to the more complex multi-slicing (MS) with figure errors.

Simulations were performed on an Intel(R) Xeon(R) CPU E5-2680 v4 @ 2.40 GHz cluster at the ESRF. Partially coherent calculations were carried out using 28 cores in parallel.

Model	Fully coherent	Partially coherent	Caustics
Single lens equivalent	33 s	2 h 44 min	1 h 32 min
Multi-slicing	58 s	5 h 12 min	1 h 33 min
MS + figure errors	2 min 48 s	5 h 42 min	1 h 35 min
