Operation Plot

Once the dependencies and DXT Explorer have been installed:

dxt-explorer DARSHAN_FILE_COLLECTED_WITH_DXT_ENABLE.darshan
Operation Plot

This will generate the base operation.html plot. The operation.html plot shows the read and write operations performed by each rank throughout the runtime of the application. Contextual information link Rank, Operation, Duration, Size, Offset, Lustre OST can also be seen by hovering over a request.

This is the expected console output when calling DXT Explorer:

Interactive examples of DXT traces collected from FLASH, E2E, and OpenPMD are available in the companion repository of our PDSW’21 paper.
