Multiple instances with prior runtime knowledge pattern

Unlike multiple instances with prior design-time knowledge, the number of multiple instances in this pattern is not known until the process is being performed and cannot be set ahead of time at design time. However, the number of multiple instances to be created is determined before the first instance of the multiple instances gets initiated. In this pattern, the pattern instances can be created in parallel and sequence.

The following table summarizes the details around multiple instances with runtime knowledge:

Signature	Multiple Instances With Prior Runtime Knowledge Pattern
Classification	Multi-instance Pattern
Intent	The number of concurrent threads is not known in advance at design time and is calculated at runtime. However, it's calculated before the first instance is created. Concurrent thread synchronization must be performed.
Motivation	The determination of the number of instances will be performed at runtime...
