Visualizing memory bandwidth utilization using memory bandwidth stack

A non-transitory computer-readable storage medium having stored thereon executable computer program instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:

• receiving, by the one or more processors, data corresponding to a memory cycle occurring during a total execution time of an application executed by the one or more processors;
• for the memory cycle, assigning the memory cycle to a component of components of a bandwidth stack based on analysis of the data and in accordance with a prioritization scheme that comprises a hierarchical accounting providing a priority to the components for assignment to the memory cycle, wherein the memory cycle is broken into cycle portions and each component is assigned to the cycle portions of the memory cycle based on the priority;
• for the component, determining a stack portion of the bandwidth stack to account to the component based at least in part on the assignment of a corresponding cycle portion of the cycle portions of the memory cycle to the component;
• and
• generating the bandwidth stack by at least representing the stack portion accounted to the component in the bandwidth stack.
