Research direction

Start by reviewing the tile-reduce documentation and the map.js operations described in the report. Determine whether CPU and memory allocation for a 32-core, 400-tile run is documented, and identify what evidence is needed to explain the change from many active cores to one. Done means the documented behavior and any confirmed cause answer the reporter's questions.

Description

Is there any documentation on how CPU and memory allocation is done for a tile-reduce script?

A tile-reduce script which is running in a 32 CPU core machines uses all the cores to process 400 tiles uses all the cores initially for 4-5 tiles and then only one CPU is allocated till the end.

What might be the issue here? Is this the issue with cached memory or because of too many operation happening inside map.js?
