Declaration

var requiredThreadsPerThreadgroup: MTLSize { get set }

Discussion

This value is typically optional, except in the cases where the tile function that tileFunctionDescriptor references uses CooperativeTensors. In this case, you need to provide a non-zero value to this property.

Additionally, when you set this value, the threadsPerTile argument of any tile dispatch needs to match it.

Setting this value to a size of 0 in every dimension disables this property.
