distributed 2021.10.0

Parameters
adapt(self, *args, minimum=0, maximum=inf, minimum_cores: 'int' = None, maximum_cores: 'int' = None, minimum_memory: 'str' = None, maximum_memory: 'str' = None, **kwargs) -> 'Adaptive'

This scales Dask clusters automatically based on scheduler activity.

Parameters

minimum : int

Minimum number of workers

maximum : int

Maximum number of workers

minimum_cores : int

Minimum number of cores/threads to keep around in the cluster

maximum_cores : int

Maximum number of cores/threads to keep around in the cluster

minimum_memory : str

Minimum amount of memory to keep around in the cluster Expressed as a string like "100 GiB"

maximum_memory : str

Maximum amount of memory to keep around in the cluster Expressed as a string like "100 GiB"

Turn on adaptivity

Examples

This example is valid syntax, but we were not able to check execution
>>> cluster.adapt(minimum=0, maximum_memory="100 GiB", interval='500ms')

Local connectivity graph

Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.

Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)

SVG is more flexible but power hungry; and does not scale well to 50 + nodes.

All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
