The caller must set both the colorType and color field. The payload attribute can be used to provide additional data for markers and ranges. Range events can only specify values at the beginning of a range. The caller must specify valid values for both payloadType and payload. Zeroing the structure sets all the event attributes types and values to the default value.

The version and size field are used by the Tools Extension implementation to handle multiple versions of the attributes structure. It is recommended that the caller use one of the following to methods to initialize the event attributes structure:. The version and size field are used by the Tools Extension implementation to handle multiple versions of the attributes structures. This example shows how to initialize the structure for forwards compatibility.

This example shows how to initialize the structure to a specific version of the library. If the caller uses Method 1 it is critical that the entire binary layout of the structure be configured to 0 so that all fields are initialized to the default value. Using a mix of the two methods will likely cause either source level incompatibility or binary incompatibility in the future. A marker can contain a text message or specify additional information using the event attributes structure. These attributes include a text message, color, category, and a payload.

Each of the attributes is optional and can only be sent out using the nvtxMarkEx function. If nvtxMarkA or nvtxMarkW are used to specify the marker, or if an attribute is unspecified, then a default value will be used. A marker created using nvtxMarkA or nvtxMarkW contains only a text message. The duration of each range is defined by the corresponding pair of nvtxRangePush and nvtxRangePop calls in the application's source code.

Nested ranges are handled automatically on a per-CPU thread basis, and no special developer code is necessary. Marks the start of a nested range. Returns the 0 based level of range being started. If an error occurs, a negative value is returned. Marks the end of a nested range. If an error occurs, a negative value is returned on the current thread. Marks the start of a range.

Categories and threads are used to group sets of events. Allows the user to name an active thread of the current process. If an invalid thread ID is provided, or a thread ID from a different process is used, the behavior of the tool is implementation-dependent.

Each of these functions combines the object handle and the name that should be assigned to the object. The namable resources in this case include: devices, context, command queues, memory objects, samplers, programs, and events. Parameters: sampler — The handle of the OpenCL sampler to name.

Both the header files and the library files themselves. In order to compile your project with NVTX support in Visual Studio, use the following steps to setup your project accordingly:. In case you use NVTX to annotate code in. It is recommended that you copy the NVTX headers and library files into your own source tree prior to integrating this API into your application. The NVTX. When linking, you may either link using the stub.

Instead, make sure to deploy the. Do not rename the. In the Trace Settings area, select the Tools Extension checkbox. Once finished configuring the activity to capture NVTX data, optionally choose any other domains or sub-options you would like to trace. Launch your application using the launch controls at the bottom of the activity page in order to run your application and capture all the specified data, including the NVTX events.

The NVTX markers and ranges are displayed in two different areas of the row hierarchy. This allows the thread to be presented:. Besides the Timeline Report, you can also select the Tools Extension Events report to view the data from a different angle. The parent row includes all nvtxMark events specified on the thread. Each category row consists of multiple stacked range graphs.

The timeline view will attempt to show the minimal number of Range rows. The ranges are not displayed as a stack. The Tools Extension Events Page provides a table view of the events. This table contains every NVTX event that was sent during the capture period. The user can use sorting and filtering to analyze the data. The data is displayed in the 'Tools Extension Events' report table as illustrated below. Parameters: category - The category ID to name.

Allows the user to name an active thread of the current process. If an invalid thread ID is provided, or a thread ID from a different process is used, the behavior of the tool is implementation-dependent. Parameters: threadId - The ID of the thread to name. Each of these functions combines the object handle and the name that should be assigned to the object. Allows the user to associate a CUDA device with a user-provided name. Allows the user to associate a CUDA context with a user-provided name.

Allows the user to associate a CUDA stream with a user-provided name. The namable resources in this case include: devices, context, command queues, memory objects, samplers, programs, and events.

Allows the association of an OpenCL device with a user-provided name. Parameters: device - The handle of the OpenCL device to name. Allows the association of an OpenCL context with a user-provided name. Parameters: context - The handle of the OpenCL context to name. Allows the association of an OpenCL command queue with a user-provided name. Allows the association of an OpenCL memory object with a user-provided name. Parameters: memobj - The handle of the OpenCL memory object to name.

Allows the association of an OpenCL sampler with a user-provided name. Parameters: sampler - The handle of the OpenCL sampler to name. Allows the association of an OpenCL program with a user-provided name. Parameters: program - The handle of the OpenCL program to name. Allows the association of an OpenCL event with a user-provided name.

Installing from source You can build and install the package from source: python setup. Building the documentation The documentation is built by running: cd docs pip install -r requirements. Quick start guide Adding markers to the graph Markers are added by wrapping parts of the computation graph with start and end operations.

Disclaimer The project is in beta stage, breaking changes are to be expected in the future.
