Detailed Description

Task event class.

This class is used to record the task trace information, including submit, start, and stop times, as well as identification information.

Member Function Documentation

get_name()

std::string madness::profiling::TaskEvent::get_name ( ) const

inlineprivate

Get name of the function pointer.

Returns

The mangled function name.

References id_.

print_demangled()

static void madness::profiling::TaskEvent::print_demangled ( std::ostream &  os, const char *  symbol  )

inlinestaticprivate

Print demangled symbol name.

Add the demangled symbol name to os. If demangling fails, the unmodified symbol name is used instead. If symbol is NULL, "UNKNOWN" is used instead. A tab character is added after the symbol name.

Parameters

[in,out]	os	The output stream.
[in]	symbol	The symbol to add to the stream.

References madness::name(), and status.

start()

void madness::profiling::TaskEvent::start ( const std::pair< void *, unsigned short > &  id, const unsigned short  threads, const double  submit_time  )

inline

Record the start time of the task and collect task information.

Parameters

[in,out]	id	The task identifier (a function pointer or const char*) and an integer to differentiate the different types.
[in]	threads	The number of threads this task uses.
[in]	submit_time	The time that the task was submitted to the task queue.

References id_, threads_, times_, and madness::wall_time().

stop()

void madness::profiling::TaskEvent::stop ( )

inline

Record the stop time of the task.

References times_, and madness::wall_time().

operator<<

std::ostream& operator<< ( std::ostream &  os, const TaskEvent &  te  )

friend

Output the task data using a tab-separated list.

Output information includes

• the ID pointer
• the function, member function, and object type name
• the number of threads used by the task
• the submit time
• the start time
• the stop time.

Parameters

[in,out]	os	The output stream.
[in]	te	The task event to be output.

Returns

The os reference.
