Hybrid in-situ processing

Definition

Hybrid in-situ processing refers to a method that combines both in-situ and in-transit data processing to enhance the efficiency and effectiveness of data analysis during high-performance computing tasks. This approach allows for real-time data analysis at the source (in-situ) while also utilizing additional resources for data processing as it moves between nodes or systems (in-transit). By leveraging both strategies, hybrid in-situ processing can provide faster insights and minimize data movement, which is crucial for handling large datasets typically encountered in exascale computing.
