SYNOPSIS

sh5util

DESCRIPTION

sh5util merges HDF5 files produced on each node for each step of a job into one HDF5 file for the job. The resulting file can be viewed and manipulated by common HDF5 tools such as HDF5View, h5dump, h5edit, or h5ls.

sh5util also has two extract modes. The first, writes a limited set of data for specific nodes, steps, and data series in "comma separated value" form to a file which can be imported into other analysis tools such as spreadsheets.

The second, (Item-Extract) extracts one data time from one time series for all the samples on all the nodes from a jobs HDF5 profile.

- Finds sample with maximum value of the item.

- Write CSV file with min, ave, max, and item totals for each node for each

sample

OPTIONS

-E, --extract

Extract data series from a merged job file.

Extract mode options

-i, --input=path

merged file to extract from (default ./job_$jobid.h5)

-N, --node=nodename

Node name to extract (default is all)

-l, --level=[Node:Totals|Node:TimeSeries]

Level to which series is attached. (default Node:Totals)

-s, --series=[Energy | Lustre | Network | Tasks | Task_#]

Tasks is all tasks, Task_# (# is a task id) (default is everything)

-I, --item-extract

Extract one data item from all samples of one data series from all nodes in a merged job file.

Item-Extract mode options

-s, --series=[Energy | Lustre | Network | Task]

-d, --data

Name of data item in series (See note below).

-j, --jobs=<job(.step)>

Format is <job(.step)>. Merge this job/step (or a comma-separated list of job steps). This option is required. Not specifying a step will result in all steps found to be processed.

-h, --help

Print this description of use.

-o, --output=path

Path to a file into which to write.
Default for merge is ./job_$jobid.h5
Default for extract is ./extract_$jobid.csv

-p, --profiledir=dir

Directory location where node-step files exist default is set in acct_gather.conf.

-S, --savefiles

Instead of removing node-step files after merging them into the job file, keep them around.

--user=user

User who profiled job. (Handy for root user, defaults to user running this command.)

--usage

Display brief usage message.

Examples

Merge node-step files (as part of a sbatch script)

sbatch -n1 -d$SLURM_JOB_ID --wrap="sh5util --savefiles -j $SLURM_JOB_ID"

Extract all task data from a node

sh5util -j 42 -N snowflake01 --level=Node:TimeSeries --series=Tasks

Extract all energy data

sh5util -j 42 --series=Energy --data=power
