Detailed Description

Markers for categorizing performance measurements.

This utility provides an interface to the Caliper source-code annotation API. Regions of code are marked and annotations are recorded in Caliper depending on the CALIPER_DETAIL CMake option. Caliper's runtime configuration can then be used to control performance measurement and collection for the annotations.

Contents are in flecsi::util::annotation unless otherwise specified.

used for specifying what detail of annotations to collect.

Function Documentation

begin() [1/3]

template<class ctx , detail severity>

std::enable_if_t< std::is_base_of< context< ctx >, ctx >::value > begin

(

const char *

region_name

)

Tag beginning of a code region with runtime name.

This is used to mark code regions with a name at runtime in contrast to using a region type.

Template Parameters

ctx	annotation context for named code region.
detail	severity detail level to use for code region.

Deprecated

Use guard.

begin() [2/3]

template<class reg >

std::enable_if_t< std::is_base_of< context< typename reg::outer_context >, typename reg::outer_context >::value > begin

(

)

Tag beginning of code region with caliper annotation.

The region is only tagged if caliper is enabled and reg::detail_level is compatible with the current annotation detail level.

Template Parameters

reg	code region to tag (type inherits from annotation::region).

Deprecated

Use rguard.

begin() [3/3]

template<class reg >

std::enable_if_t< std::is_base_of< context< typename reg::outer_context >, typename reg::outer_context >::value && std::is_base_of< execute_task< reg >, reg >::value > begin

(

std::string_view

task_name

)

Tag beginning of an execute_task region.

The execute_task region has multiple phases and is associated with a named task.

Template Parameters

reg	code region to tag (must inherit from annotation::execute_task).

Parameters

task_name

name of task to tag.

Deprecated

Use rguard.

end() [1/2]

template<class ctx , detail severity>

std::enable_if_t< std::is_base_of< context< ctx >, ctx >::value > end

(

)

Tag end of a named code region.

This is used for runtime named code regions (in contrast using region types).

Template Parameters

ctx	annotation context for named code region.
detail	severity detail level to use for code region.

Deprecated

Use guard.

end() [2/2]

template<class reg >

std::enable_if_t< std::is_base_of< context< typename reg::outer_context >, typename reg::outer_context >::value > end

(

)

Tag end of code region using a region type.

The region is only tagged if caliper is enabled and reg::detail_level is compatible with the current annotation detail level.

Template Parameters

reg	code region to tag (type inherits from annotation::region).

Deprecated

Use rguard.
