Typedef Documentation

reaction_stats_t

Function Documentation

main()

int main	(	int	argc,
		const char *	argv[] )

process_args()

int process_args	(	int	argc,
		const char *	argv[],
		char **	root,
		instant_t *	start_time,
		instant_t *	end_time )

read_and_write_trace()

size_t read_and_write_trace	(	instant_t	trace_start_time,
		instant_t	trace_end_time )

Read a trace in the trace_file and write it to the output_file as CSV.

Returns

The number of records read or 0 upon seeing an EOF.

string_to_instant()

instant_t string_to_instant	(	const char *	time_spec,
		const char *	units )

usage()

void usage

(

)

Print a usage message.

write_summary_file()

void write_summary_file

(

)

Write the summary file.

Variable Documentation

latest_time

instant_t latest_time = 0LL

Largest timestamp seen.

output_file

FILE* output_file = NULL

File for writing the output data.

summary_file

FILE* summary_file = NULL

File for writing summary statistics.

summary_stats

summary_stats_t** summary_stats

Summary stats array. This array has the same size as the object table. Pointer in the array will be void if there are no stats for the object table item.

table_size

int table_size

Size of the stats table is object_table_size plus twice MAX_NUM_WORKERS.

trace_file

FILE* trace_file = NULL

File containing the trace binary data.
