Typedefs
using	DeviceTexture = void *
	Type of device texture object. In SYCL, that would be sycl::image, but it's not used.
using	CommandEvent = void *
	Single GPU call timing event, not used with SYCL.
using	Float4 = sycl::float4
	Convenience alias.
using	Float3 = gmx::RVec
	Convenience alias. Not using sycl::float3 due to alignment issues.
using	Float2 = sycl::float2
	Convenience alias for sycl::float2.

Macro Definition Documentation

#define c_canEmbedBuffers   true

Sets whether device code can use arrays that are embedded in structs.

That is not technically true for SYCL: the device code needs dedicated sycl::buffer/accessor objects. But our prepareGpuKernelArguments and launchGpuKernel functions deal with that, so we can pass embedded buffers to them, which is what this constant actually controls.
