How to estimate the CPU resource required to execute certain number of tasks on data. Is there any method or formula to estimate how many (nodes/servers) will be required, given number of tasks and data size. In my scenario, IoT data sources are emitting data and I have to select group of nodes (fog nodes) to execute some tasks (tasks can be sum/min/max/count/AVG)on the data. Prior to group selection, I have to estimate how many nodes should be selected in a group that are enough to execute the tasks on the input data.(Nodes are heterogeneous in terms of CPU resource (compute resource )and network resource)
Given the two metrics (data size and number of tasks), is there any formula or method for the estimation of required CPU resource.
