Adjusting execution of tasks in a dispersed storage network

A computer readable storage medium comprises:

• at least one memory section that stores operational instructions that, when executed by one or more processing modules of one or more computing devices of a dispersed storage network (DSN), causes the one or more computing devices to:
• receive, over time and by a set of execution units of the DSN, a plurality of sets of sub-task requests from a computing device of the DSN, wherein the computing device generates a plurality of task requests, wherein a task request of the plurality of task requests includes a set of sub-task requests and wherein the computing device sends corresponding sets of sub-task requests to the set of execution units when task requests of the plurality of task requests are generated;
• store, by the set of execution units, the corresponding sets of sub-task requests, wherein each of a first, a second, and a third execution unit of the set of execution unit stores, respectively, a first, a second, and a third sub-task request of each of the corresponding sets of sub-task requests to produce, respectively, a first, a second, and a third plurality of sub-task requests;
• respectively generate first, second, and third sub-task estimation data for the first, the second, and the third plurality of sub-task requests by the first, the second, and the third execution units;
• and
• respectively adjust timing, sequencing, or processing of the first, the second, and the third plurality of sub-task requests by the first, the second, and the third execution units based on the first, the second, and the third sub-task estimation data to produce a first, a second, and a third plurality of partial results, wherein, due to one or more difference factors from a list of difference factors, the first, the second, and the third execution units process the first, the second, and the third plurality of sub-task requests at difference paces, wherein the list of difference factors includes differences in amounts of data to be processed per sub-task request, processing capabilities, memory storage capabilities, and networking capabilities.

An execution unit of a dispersed storage network (DSN), the execution unit comprises:

• an interface;
• a memory;
• and
• a processing module operably coupled to the interface and the memory, wherein the processing module functions to:
• receive, over time via the interface, a plurality of sub-task requests from a computing device of the DSN, wherein a plurality of sets of sub-task requests includes the plurality of sub-task requests, wherein the computing device generates a plurality of task requests, wherein a task request of the plurality of task requests includes a set of sub-task requests, wherein the computing device sends corresponding sets of sub-task requests to a set of execution units of the DSN when task requests of the plurality of task requests are generated and wherein the set of execution units includes the execution unit;
• store, in the memory, a corresponding sub-task request of each of the corresponding sets of sub-task requests to produce the plurality of sub-task requests;
• generate sub-task estimation data for the plurality of sub-task requests;
• and
• adjust timing, sequencing, or processing of the plurality of sub-task requests based on the estimation data to produce a plurality of partial results, wherein, due to one or more difference factors from a list of difference factors, the execution unit process the plurality of sub-task requests at difference paces, wherein the list of difference factors includes differences in amounts of data to be processed per sub-task request, processing capabilities, memory storage capabilities, and networking capabilities.
