Method, device and computer program product for determining execution progress of task
Embodiments of the present disclosure relate to a method, a device, and a computer program product for determining an execution progress of tasks. The method includes determining, according to a determination that a task is executed, whether historical execution information of the task is available. The method further includes determining the expected execution duration of the task based on the historical execution information of the task according to a determination that the historical execution information of the task is available. The method further includes determining the duration of completed execution for the task based on the time point at which execution of the task begins and the current time point. The method further includes determining the execution progress of the task based on the expected execution duration and the completed execution duration.

determining that the number of times is above a threshold number;
selecting a predetermined number of historical execution durations from the set of historical execution durations in response to the number of times being above the threshold number; and
determining the expected execution duration by performing an operation on the predetermined number of historical execution durations;
determining a completed execution duration for the task based on a starting time point at which execution of the task began and a current time point;
determining an execution progress of the task based on the expected execution duration and the completed execution duration, wherein the execution progress is more accurate than a progress based solely on the completed execution; and
providing the execution progress to a user of the computing device.
2. The method of claim 1 , wherein determining the expected execution duration further comprises:
determining, based on the historical execution information, a second number of times the task has been executed and a second set of historical execution durations corresponding to respective executions;
determining that the second number of times is below a second threshold number;
determining the expected execution duration by performing a second operation on the second set of historical execution durations in response to the second number of times not being above the threshold number.
3. The method of claim 1 , further comprising:
determining a first number of sub-tasks comprised in a second task according to a determination that second historical execution information for the second task is not available;
determining a second number of completed sub-tasks in the second task;
determining a degree of completion of sub-tasks being executed in the second task; and
determining the execution progress of the second task based on the first number, the second number, and the degree of completion.
4. The method of claim 1 , further comprising:
determining whether the execution progress indicates that the task has been completed; and
according to a determination that the execution progress indicates the task has been completed, determining whether the task has actually been completed; and
setting the execution progress to a predetermined value according to a determination that the task has not actually been completed.
5. An electronic device, comprising:
a processor; and
a memory storing computer program instructions, the processor running the computer program instructions in the memory to control the electronic device to perform a method, the method comprising:
obtaining historical execution information of a task from a storage apparatus of a computing device;
determining an expected execution duration of the task based on the historical execution information of the task, wherein determining the expected execution duration comprises:
determining, based on the historical execution information, a number of times the task has been executed and a set of historical execution durations corresponding to respective executions;
determining that the number of times is above a threshold number;
selecting a predetermined number of historical execution durations from the set of historical execution durations in response to the number of times being above the threshold number; and
determining the expected execution duration by performing an operation on the predetermined number of historical execution durations;
determining a completed execution duration for the task based on a starting time point at which execution of the task began and a current time point;
determining an execution progress of the task based on the expected execution duration and the completed execution duration, wherein the execution progress is more accurate than a progress based solely on the completed execution; and
providing the execution progress to a user of the computing device.
6. The electronic device of claim 5 , wherein determining the expected execution duration further comprises:
determining, based on the historical execution information, a second number of times the task has been executed and a second set of historical execution durations corresponding to respective executions;
determining that the second number of times is below a second threshold number;
determining the expected execution duration by performing a second operation on the second set of historical execution durations in response to the second number of times not being above the threshold number.
7. The electronic device of claim 5 , wherein the method further comprises:
determining a first number of sub-tasks comprised in a second task according to a determination that second historical execution information for the second task is not available;
determining a second number of completed sub-tasks in the second task;
determining a degree of completion of sub-tasks being executed in the second task; and
determining the execution progress of the second task based on the first number, the second number, and the degree of completion.
8. The electronic device of claim 5 , wherein the method further comprises:
determining whether the execution progress indicates that the task has been completed; and
according to a determination that the execution progress indicates the task has been completed, determining whether the task has actually been completed; and
setting the execution progress to a predetermined value according to a determination that the task has not actually been completed.
9. A computer program product tangibly stored in a non-transitory computer-readable medium and comprising machine-executable instructions, wherein when executed, the machine-executable instructions cause a machine to perform a method comprising:
obtaining historical execution information of a task from a storage apparatus of a computing device;
determining an expected execution duration of the task based on the historical execution information of the task, wherein determining the expected execution duration comprises:
determining, based on the historical execution information, a number of times the task has been executed and a set of historical execution durations corresponding to respective executions;
determining that the number of times is above a threshold number;
selecting a predetermined number of historical execution durations from the set of historical execution durations in response to the number of times being above the threshold number; and
determining the expected execution duration by performing an operation on the predetermined number of historical execution durations;
determining a completed execution duration for the task based on a starting time point at which execution of the task began and a current time point;
determining an execution progress of the task based on the expected execution duration and the completed execution duration, wherein the execution progress is more accurate than a progress based solely on the completed execution; and
providing the execution progress to a user of the computing device.
10. The computer program product of claim 9 , wherein determining the expected execution duration further comprises:
determining, based on the historical execution information, a second number of times the task has been executed and a second set of historical execution durations corresponding to respective executions;
