Abstract

A system is configured to: conduct asynchronous updates, of a display, based on a fixed rate when operating in an asynchronous state; determine whether to switch to a synchronous state from the asynchronous state based on the asynchronous updates; conduct synchronous updates, of the display, after switching to the synchronous state; receive a lock request, and conduct updating of the display based on the lock request. The synchronous updates may be performed independent of the fixed rate.

First claim

What is claimed is:

1. One or more non-transitory computer-readable media storing instructions, the instructions comprising:
one or more instructions that, when executed by one or more processors, cause the one or more processors to:
receive, during a first period of time and at a first frequency, a first set of data generated during an execution of a model;
determine that the first frequency is less than a threshold frequency for receiving data generated during the execution of the model,
the threshold frequency being based on an ability to perceive changes to a visual representation;

perform, during the first period of time and based on the first frequency being less than the threshold frequency, a synchronous update of a display of the visual representation of the execution of the model using the first set of data;
receive, during a second period of time and at a second frequency, a second set of data generated during the execution of the model;
determine that the second frequency is not less than the threshold frequency; and
perform, during the second period of time and based on the second frequency not being less than the threshold frequency, an asynchronous update of the visual representation,
the one or more instructions to perform the asynchronous update of the visual representation including:
one or more instructions that, when executed by the one or more processors, cause the one or more processors to:
 buffer the second set of data in a memory, and
 update the display of the visual representation at a third frequency, that is less than the threshold frequency, using the buffered second set of data.

2. The one or more non-transitory computer-readable media of claim 1 , where the threshold frequency is set at or above 20 Hz.

3. The one or more non-transitory computer-readable media of claim 1 , where the instructions further comprise:
one or more instructions that, when executed by the one or more processors, cause the one or more processors to:
receive, during a third period of time and at a fourth frequency, a third set of data generated during the execution of the model;
determine that the fourth frequency is less than the threshold frequency;
determine whether the memory includes additional data for updating the visual representation; and
perform the synchronous update of the display of the visual representation using the third set of data when the memory does not include the additional data.

4. The one or more non-transitory computer-readable media of claim 3 , where the instructions further comprise:
one or more instructions that, when executed by the one or more processors, cause the one or more processors to:
perform the asynchronous update of the display of the visual representation using the third set of data when the memory includes the additional data.

5. The one or more non-transitory computer-readable media of claim 1 , where the instructions further comprise:
one or more instructions that, when executed by the one or more processors, cause the one or more processors to:
receive a request to switch to a synchronous lock state;
switch to the synchronous lock state based on the request;
receive a third set of data at the second frequency; and
perform the synchronous update of the display of the visual representation using the third set of data based on switching to the synchronous lock state.

6. The one or more non-transitory computer-readable media of claim 1 , where the visual representation includes a graph,
where the one or more instructions to receive the first set of data include:
one or more instructions that, when executed by the one or more processors, cause the one or more processors to:
receive information identifying coordinates corresponding to a series of points; and

where the one or more instructions to perform the synchronous update include:
one or more instructions that, when executed by the one or more processors, cause the one or more processors to:
cause a plot of the series of points to be displayed on the graph based on the coordinates.

7. The one or more non-transitory computer-readable media of claim 1 , where the one or more processors are included in a first computing device; and
where the one or more instructions to receive the first set of data include:
one or more instructions that, when executed by the one or more processors, cause the one or more processors to:
receive, from a second computing device and via a network, the first set of data,
the second computing device executing the model to generate the first set of data.

8. The one or more non-transitory computer-readable media of claim 1 , where the one or more instructions to update the display of the visual representation at the third frequency include:
one or more instructions that, when executed by the one or more processors, cause the one or more processors to:
measure a wait time from when a last update of the display of the visual representation was performed,
determine whether the wait time corresponds to the third frequency, and
update the display of the visual representation when the wait time corresponds to the third frequency.

9. A device comprising:
one or more processors to:
obtain, during a first period of time and at a first frequency, a first set of data generated during an execution of a model;
determine that the first frequency is less than or equal to a threshold frequency associated with updating a display of a visual representation of the execution of the model,
the threshold frequency being based on an ability to perceive changes to a visual representation;

perform, during the first period of time and based on the first frequency being less than or equal to the threshold frequency, a synchronous update of the display of the visual representation using the first set of data;
obtain, during a second period of time and at a second frequency, a second set of data generated during the execution of the model;
determine that the second frequency is greater than the threshold frequency; and
perform, during the second period of time and based on the second frequency being greater than the threshold frequency, an asynchronous update of the visual representation,
when performing the asynchronous update of the visual representation, the one or more processors being to:
buffer the second set of data in a memory, and
update the display of the visual representation at a third frequency using the buffered second set of data.

10. The device of claim 9 , where the threshold frequency is set at or above 20 Hz.

11. The device of claim 9 , where the one or more processors are further to:
receive, during a third period of time and at a fourth frequency, a third set of data generated during the execution of the model;
determine that the fourth frequency is less than or equal to the threshold frequency;
determine whether the memory includes additional data for updating the visual representation; and
perform the synchronous update of the display of the visual representation using the third set of data when the memory does not include the additional data.

12. The device of claim 11 , where the one or more processors are further to:
perform the asynchronous update of the display of the visual representation using the third set of data when the memory includes the additional data.

13. The device of claim 9 , where the one or more processors are further to:
receive a request to switch to a synchronous lock state;
switch to the synchronous lock state based on the request;
receive a third set of data at the second frequency; and
perform the synchronous
