Function Documentation

double get_time_of_day

(

)

Returns current time.

Returns

Current Unix time in seconds as a double-precision number.

Definition at line 66 of file svg_trace.c.

void svg_trace_init	(	int	num_cores,
		int	num_devices
	)

Initializes tracing.

Parameters

num_cores	– The number of cores.
num_devices	– The number of devices.

Definition at line 81 of file svg_trace.c.

void svg_trace_memory_device

(

long

delta)

Register device memory usage.

Parameters

delta

– The change of host memory usage in bytes.

Definition at line 243 of file svg_trace.c.

void svg_trace_memory_host

(

long

delta)

Registers host memory usage. The operation has to be atomic, because it can be invoked by a callback. Because there are two variables to keep track of, the level and the maximum, doing it with atomics is not worth it. Using a spinlock instead.

Parameters

delta

– The change of host memory usage in bytes.

Definition at line 228 of file svg_trace.c.

void svg_trace_start_cpu

(

int

thread_rank)

Starts tracing of a CPU event.

Parameters

thread_rank

– The rank of the thread.

Definition at line 125 of file svg_trace.c.

void svg_trace_start_dma

(

cudaStream_t

stream)

Starts tracing a DMA event.

Parameters

stream

– The stream of the event.

Definition at line 189 of file svg_trace.c.

void svg_trace_start_gpu

(

cudaStream_t

stream)

Starts tracing a GPU event.

Parameters

stream

– The stream of the event.

Definition at line 153 of file svg_trace.c.

void svg_trace_stop_cpu	(	int	thread_rank,
		int	color
	)

Stops tracing a CPU event.

Parameters

thread_rank	– The rank of the thread.
color	– The RGB color of the SVG box.

Definition at line 138 of file svg_trace.c.

void svg_trace_stop_dma	(	cudaStream_t	stream,
		int	color
	)

Stops tracing a DMA event.

Parameters

stream	– The stream of the event.
color	– The RGB color of the SVG box.

Definition at line 206 of file svg_trace.c.

void svg_trace_stop_gpu	(	cudaStream_t	stream,
		int	color
	)

Stops tracing a GPU event.

Parameters

stream	– The stream of the event.
color	– The RGB color of the SVG box.
