Compute Shader Vulkan Tutorial The number of work groups that a compute operation is executed with is defined by the user when they invoke the compute operation. the space of these groups is three dimensional, so it has a number of "x", "y", and "z" groups. Before we get into how a compute shader works and how we submit compute workloads to the gpu, we need to talk about two important compute concepts: work groups and invocations.
Overview Of A Compute Shader Dispatch The Top Figure Shows The Layout There are two key concepts to understand how threads are organized in webgpu: workgroup size and workgroup count. the workgroup size defines the number of threads that execute together. What is the point of having work groups? how are they useful, compared to just having nxm independent pixel calculations with a known (x,y) input parameter in the shader?. In compute shaders, there is a split beetween individual elements, and “work groups”, which are groups of individual elements. elements within the same workgroup can do some features such as access workgroup local memory in a fast way, which is useful for many operations. We’re going to start with some basic of compute shaders and then hopefully move on to examples of solving real world problems. in the previous article we made an extremely simple compute shader that doubled numbers in place.

For the best performance for a specific shader, you will need to profile different combinations of workgroup size and number of workgroups, but this articles might give you some more hints on how to determine sizes:. When compute shader work is dispatched from the cpu, it’s the number of groups that is specified in the command, which means that the granularity of work on the gpu is actually the group and not a single thread. Now we have the opportunity to compare the gpu load for our different versions. the first version has a high load on the gpu over a long time, in fact it extends beyond the length of the plot. While vertex and fragment shaders are used in a render pipeline, compute shaders can only be used in another type of pipeline, called a compute pipeline. this section discusses how to create and use compute shaders and compute pipelines.
