Computational input

The inputs give the user a bit more control over the computational aspects of FIAT.

Table 1: Computational FIAT input settings

Entry	Type	Default
[global]
threads	integer	1
[global.geom]
chunk	integer	-
[global.grid]
chunk	list	-

Warning

All settings that are not globally defined (e.g. settings chunk size via hazard.settings) are ill-advised. Please use the global chunking settings.

[global]

• threads: Set the number of threads of the calculations. If this number exceeds the cpu count, the amount of threads will be capped by the cpu count.

[global.geom]

• chunk: Set the chunk size of the geometry calculations. The calculations will then be done in vectors of these lengths in parallel. This settings will also be used for chunking when writing.

Tip

This input benefits from multiple threads.

Note

This input is only applicable to the GeomModel

[global.grid]

• chunk: Set the chunk size for the gridded calculations. This will chunk the data in rectangles with the goal of reducing the memory foodprint. An example would be [1024, 1024,].

Note

This input is only applicable to the GridModel
