Examples described herein generally relate to reporting memory resource access by a graphics processing unit (GPU). A list of memory resources allocated for the GPU can be received by a memory tracking application. An indication of memory resource utilization based on the list of memory resources can be displayed on an interface. The memory tracking application can also receive, from the GPU, multiple indications that one or more of the memory resources allocated for the GPU are accessed, and can update the indication of memory resource utilization based at least in part on the multiple indications.

Techniques for tracking graphics processing resource utilization

The techniques and systems described herein are directed to capturing commands in a multi-engine graphics processing unit (GPU). Captured commands can be played back by a developer to optimize software, hardware, and drivers. To accurately capture commands and memory associated with the commands during execution, dependencies between command buffer segments associated with the various GPU engines may be determined and used to divide a command buffer segment into atomic elements (which may also be referred to as seglets). Command buffer segments are analyzed to identify synchronization commands, which may represent a point in a command buffer segment that relies on an operation to be completed in another command buffer segment. The command buffer segment can be recursively divided into seglets based on the synchronization commands. The resulting seglets represent command segments that, upon execution, operate without synchronization interference from other command buffer segments.
