hpcprof
analyzes call path profile performance measurements,
attributes them to static source code structure,
and generates an experiment database for use with hpcviewer(1)
.
For analyzing and attributing the performance of large-scale executions,
use hpcprof-mpi(1)
, a parallel version of hpcprof.
hpcprof
expects a list of measurement groups,
each of which is either a call path profile directory or an individual profile file.
For best results, two other options should be given:
-I
to specify search directories for source code files
and -S
to provide a source code structure file generated by hpcstruct(1)
.
If no search directory arguments are given,
hpcprof
will find only those source files that are specified via
either an absolute path still preseent in the file system
or a relative path w.r.t. the current working directory.
- measurement-group...
- A sequence of file system paths,
each speciufying a call path profile directory or an individual profile file.
Default values for an option's optional arguments are shown in {}.
- -v [n], --verbose [n]
-
Print progress messages to stderr at verbosity level n.
{1}
- -V, --version
-
Print version information.
- -h, --help
-
Print help.
- --debug [n]
-
Print debugging messages at level n.
{1}
- --name name, --title name
-
Set the database's name (title) to name.
- -I dir, --include dir
-
Use dir
as a search directory to find source files.
For a recursive search, append a '+' after the last slash, e.g., /mypath/+.
This option may be given multiple times.
If a file appears in more than one search directory,
the ambiguity is resolved in favor of the search directory which occurred first on the command line.
- -S file, --structure file
-
Use the structure file file
produced by hpcstruct(1)
to identify source code elements for attribution of performance.
This option may be given multiple times,
e.g. to provide structure for shared libraries in addition to the application executable.
- -R 'old-path=new-path', --replace-path 'old-path=new-path'
-
Replace every instance of old-path
by new-path
in all paths for which old-path
is a prefix (e.g., in a profile's load map and source code).
Use '\' to escape instances of '=' within a path.
This option may be given multiple times.
Use this option when a profile or binary contains references to files that have been relocated,
such as might occur with a file system change.
- -M metric, --metric metric
-
Compute the specified metrics, where metric
is one of the following:
- sum
- Sum over threads/processes
- stats
- Sum, Mean, StdDev (standard deviation), CoefVar (coefficient of variation),
Min, Max over threads/processes
- thread
- per-thread/process metrics
Note that hpcprof-mpi(1)
cannot compute thread.
The default metric is sum.
This option may be given multiple times.
- --force-metric
-
Show all thread-level metrics regardless of their number.
- --normalize all | none
-
If this option is all,
normalize call paths in profiles to hide implementation details;
if none,
do not normalize.
If not given, the default is all..
- -o db-path, --db db-path, --output db-path
-
Write the computed experiment database to db-path.
The default path is ./hpctoolkit-<application>-database.
- --remove-redundancy
-
Eliminate procedure name redundancy in output file experiment.xml.
- --struct-id
-
Add 'str=nnn' field to profile data with the hpcstruct node id.
The default is no.
