secede()

This opens up a new scheduling slot and a new thread for a new task. This enables the client to schedule tasks on this node, which is especially useful while waiting for other jobs to finish (e.g., with client.gather ).

Have this task secede from the worker's thread pool

Examples

This example is valid syntax, but we were not able to check execution
>>> def mytask(x):
...  # do some work
...  client = get_client()
...  futures = client.map(...) # do some remote work
...  secede() # while that work happens, remove ourself from the pool
...  return client.gather(futures) # return gathered results

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
