QUESTION

How to fix "Buffer preloading failed" compute shader performance issue?

Asked 2018-Jun-20 at 17:14

When capturing a GPU frame from my application I see the following messages under Pipeline Statistics -> Remarks:

Buffer preloading failed

Make sure your data size is a multiple of 4 bytes and aligned to 4 bytes and try using a simple access pattern. For constant buffers, try using a fixed buffer size.

pointLightBufferCenterAndRadius could not be promoted - lightCuller.metal:light_culler

Here's my buffer initialisation:

This warning is usually not an indication of a catastrophic performance hit. So resolving this probably won't give you big gains and you may want to look at optimizing other parts of the kernel.

The main way to avoid getting this is by using a [[ stage_in ]] input in your vertex shader or compute kernel to get per vertex/thread data. This isn't always possible depending on the algorithm used since you may not be able to accessing data "in order" as a [[ stage_in ]] input does.

QUESTION

SPIR-V error with InterlockedMax after upgrading to LunarG SDK 1.0.68.0

Asked 2018-Feb-16 at 17:36

My compute shader (written in HLSL) compiled and worked with the earlier SDK 1.0.65.0. I updated to 1.0.68.0 and recompiled it, now I get this error when calling vkCreateShaderModule:

Vulkan error: [SC], code: 5: SPIR-V module not valid: AtomicSMax: expected Result Type to be int scalar type

I verified that the error comes from this function in my shader:

If the SPIR-V validator says that something generated by glslangValidator is invalid, then that is either a glslangValidator bug or a SPIR-V validator bug. Probably best to file a bug at https://github.com/KhronosGroup/glslang; if the maintainers there think they're doing the right thing, they'll follow up with the spirv-tools people.

Though looking at the HLSL InterlockedMax docs, isn't it supposed to have three parameters? The glslangValidator bug here may just be a failure to issue an error for invalid input. But I'm not an HLSL expert, maybe there some other variant with two parameters and a return value.
