I/O Phase Plot

Once the dependencies and DXT Explorer have been installed:

dxt-explorer -i DARSHAN_FILE_COLLECTED_WITH_DXT_ENABLE.darshan

This will generate the base io-phase.html plot. The io-phase.html plot shows the different I/O Phases in the data. The plot also shows information regarding the number of I/O phases in each interface (MPIIO and POSIX) and the threshold value used to merge the phases. The threshold value is computed by summing the mean and standard deviation of all the intervals between the I/O phases. Contextual information link Fastest Rank, Fastest Rank Duration, Slowest Rank, Slowest Rank Duration can also be seen by hovering over a phase.

This is the expected console output when calling DXT Explorer:
