Synopsis

hpcprof [options] measurement-group...

Description

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, where a group is a call path profile directory or an individual profile file. For best results, two other options should be used: -I to provide search directories for source code and -S to provide source code structure from hpcstruct(1) . (Note that without any search-directory argument, hpcprof will only find source files that either (1) have absolute paths (and that still exist on the file system) or (2) are relative to the current working directory.)

Arguments

measurement-group...

A list of measurement-groups, where a group is a call path profile directory or an individual profile file.

Default values for an option's optional arguments are shown in {}.

Options: Informational

-v [n], --verbose [n]

Verbose: generate progress messages to stderr at verbosity level n. {1}

-V, --version

Print version information.

-h, --help

Print help.

--debug [n]

Debug: use debug level n. {1}

Options: Source Code and Static Structure

--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/+. May pass -I multiple times.

Note: With multiple search-directory arguments, it may be the case that file f exists within more than one search directory. In this case, the ambiguity is resolved in favor of the search directory that appears first on the command line.

-S file, --structure file

Use hpcstruct(1) structure file file for correlation. May pass multiple times (e.g., for shared libraries).

-R 'old-path=new-path', --replace-path 'old-path=new-path'

Substitute instances of old-path with new-path; apply to all paths (e.g., a profile's load map and source code) for which old-path is a prefix. Use '\' to escape instances of '=' within a path. May pass 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.

Options: Metrics

-M metric, --metric metric

Specify the set of metrics to compute, 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

Default is 'sum'. May pass multiple times. (hpcprof-mpi(1) does not compute 'thread'.)

Options: Output

-o db-path, --db db-path, --output db-path

Specify Experiment database name db-path. {./hpctoolkit-<application>-database}
