This sample demonstrates the use of the Command Throttle Policy extension with a simple matrix multiplication compute shader kernel.
To validate the extension is working correctly, just build and run the sample. If you want to verify the performance difference with
the extension engaged vs. not engaged, run it one time without any parameters, and run it again with the additional flag
--disable-command-throttle-policy-extension.
The sample relies on an external dependency, DXSampleHelper.h from the DirectX SDK Samples available at https://github.com/microsoft/DirectX-Graphics-Samples/tree/master. Copy this to the project folder.
This sample relies on the Intel Extensions static library available at: https://github.com/GameTechDev/64-bit-Typed-Atomics-Extension/blob/main/INTC_Atomic_64bit_Max/bin/x64/Debug/igdext64.lib or https://github.com/GameTechDev/D3DExtensions_public. Copy this to ..\CmdThrottlePolicy\IntelExtension\lib.
Supported command line parameters:
-
--disable-command-throttle-policy-extension
Don't use the command throttle policy extension. By default we will set the command throttle
policy to MAX_PERFORMANCE with the Command Throttle Policy Extension. -
--check-gpu-result
Do matrix multiplication on CPU and compare the result with the one on GPU. -
-h
Print helper information.
