Figures 3 and 4 in "A Year in the Life of a Parallel File System" show mislabeled dates for the Mira (mira-fs1) dataset. For example, Fig. 4 shows no data for Sept 15, 17, and 20 when in fact these blank dates should be Sept 12, 14, and 17. This error does not affect any numerical results presented in the paper.
In addition, the specific _datetime_start and _datetime_end timestamps
contained in the summaries/mira-summaries_2017-02-14_2018-02-15.csv.gz
dataset, as of October 16, 2018, do not match the epoch timestamps of the
darshan_start_time feature. The value stored in darshan_start_time is the
ground-truth correct timestamp, and this can be verified using the Darshan logs
included in the full year-long dataset.
The incorrect values for _datetime_start and _datetime_end resulted from
converting the string representation of the jobs' start/end times (e.g.,
2017-08-01 02:33:53) into UTC-based timestamps assuming the strings were
localized to the America/Los_Angeles time zone instead of America/Chicago
time zone where those datetime strings were actually encoded. This has no
effect on the numerical results presented in the paper and only affects the
specific way in which the Mira (mira-fs1) dataset was visualized in Figures 3
and 4.
