.SH "NAME"
.LP
sh5util \- Tool for merging HDF5 files from the acct_gather_profile
plugin that gathers detailed data for jobs running under Slurm

.SH "SYNOPSIS"
.LP
sh5util

.SH "DESCRIPTION"
.LP
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.
.LP
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.
.LP
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.
.LP
\- Finds sample with maximum value of the item.
.LP
\- Write CSV file with min, ave, max, and item totals for each node for each
sample

.SH "PERFORMANCE"
.PP
Executing \fBsh5util\fR sends a remote procedure call to \fBslurmctld\fR. If
enough calls from \fBsh5util\fR or other Slurm client commands that send remote
procedure calls to the \fBslurmctld\fR daemon come in at once, it can result in
a degradation of performance of the \fBslurmctld\fR daemon, possibly resulting
in a denial of service.
.PP
Do not run \fBsh5util\fR or other Slurm client commands that send remote
procedure calls to \fBslurmctld\fR from loops in shell scripts or other
programs. Ensure that programs limit calls to \fBsh5util\fR to the minimum
necessary for the information you are trying to gather.

.SH "EXAMPLES"

.TP
Merge node\-step files (as part of a sbatch script):

.fi

.TP

.fi

.TP
