TotalView allows access to the ROCm HIP built-in runtime variables, which are handled by TotalView like any other variables, except that you cannot change their values.

The supported ROCm HIP built-in runtime variables are as follows:

struct dim3_32 threadIdx;

struct dim3_32 blockIdx;

struct dim3_32 blockDim;

struct dim3_32 gridDim; // Grid sizes in work-group units

struct dim3_32 gridDimWorkItems; // Grid sizes in work-item units

int warpSize;

unsigned int hipThreadIdx_x, hipThreadIdx_y, hipThreadIdx_z;

unsigned int hipBlockIdx_x, hipBlockIdx_y, hipBlockIdx_z;

unsigned int hipBlockDim_x, hipBlockDim_y, hipBlockDim_z;

unsigned int hipGridDim_x, hipGridDim_y, hipGridDim_z;

The types of the built-in variables are defined as follows:

struct dim3_32 { unsigned int x, y, z; };
