Abstract

A visualization system may receive first data indicating a first occurrence of a first event. The first event may be associated with a first kernel at a first time. The second event may relate to a processor operation, a memory operation, a disk operation, and the like. The visualization system may receive second data indicating a second occurrence of a second event. The second event may be associated with a second kernel at a second time. The second event may relate to an operation of the second kernel. The first kernel may correspond to a central processing unit, and the second kernel may correspond to a graphic processing unit. The visualization system may provide, based on the first and second data, a human-perceptible representation of the duration between the first time and the second time. The visualization system may provide a timeline that represents the first data and the second data.

Claims

1. A method comprising:

receiving first data indicating a first occurrence of a first event associated with a first kernel at a first time;

receiving second data indicating a second occurrence of a second event associated with a second kernel at a second time;

providing, based on the first data and the second data, a human-perceptible representation of the duration between the first time and the second time.

2. The method of claim 1, wherein the first kernel corresponds to a central processing unit.

3. The method of claim 2, wherein receiving first data comprises receiving the first data from a log file.

4. The method of claim 1, wherein the second kernel corresponds to a graphics processing unit.

5. The method of claim 4, further comprising providing a graph, the graph representing a queue corresponding to the second kernel.

6. The method of claim 1, wherein receiving a first kernel event comprising receiving a first kernel event from a circular buffer.

7. The method of claim 6, further comprising determining a start state from an end state and a plurality of kernel events.

8. The method of claim 1, wherein the first event records at least one of a processor operation, a memory operation, and a disk operation.

9. The method of claim 1, further wherein the human-perceptible representation comprises third data indicative of a vertical synchronization interval.

10. The method of claim 1, further comprising identifying a serialization of processing between the first kernel and the second kernel.

11. A computer readable storage medium having stored thereon computer executable instructions for performing a method comprising:

mapping to a timeline first data indicative of a first event that is associated with a first kernel;

mapping to the timeline second data indicative of a second event that is associated with a second kernel; and

providing a human-perceptible representation of the timeline.

12. The computer readable storage medium of claim 11, wherein the first kernel corresponds to a central processing unit.

13. The computer readable storage medium of claim 11, wherein the first event are stored in a log file.

14. The computer readable storage medium of claim 11, wherein the second kernel corresponds a graphics processing unit.

15. The computer readable storage medium of claim 11, wherein the first event records at least one of a processor operation, a memory operation, and a disk operation.

16. The computer readable storage medium of claim 11, further comprising identifying a serialization of processing between the first kernel and the second kernel based on the first data and the second data.

17. A visualization system comprising:

an event processor that receives a first and second data, the first data indicating a first occurrence of a first event associated with a first kernel at a first time and the second data indicating a second occurrence of a second event associated with a second kernel at a second time; and

a display module that provides, based on the first and second data, a human-perceptible representation of the duration between the first time and the second time.

18. The system of claim 17, wherein the first kernel corresponds to a central processing unit.

19. The system of claim 17, wherein the second kernel corresponds to a graphics processing unit.

20. The system of claim 17, wherein the display module is adapted to identify a serialization of processing between the first kernel and the second kernel from the timeline.
