DPCT1060
Message
SYCL range can only be a 1D, 2D, or 3D vector. Adjust the code.
Detailed Help
This warning is emitted when the number of dimensions of memory in the original
code exceeds 3. Since SYCL* range supports only 1, 2 or 3 dimensions, the resulting
code is not SYCL-compliant.
To fix the resulting code you can use the low-dimensional arrays to simulate
high-dimensional arrays.
The following fix example demonstrates how to use a 3D array to simulate a 4D array.
The following migrated DPC++ code:
// migrated DPC++ code:
dpct::constant_memory<int, 4> array(dimX, dimY, dimZ, dimW);
void kernel(sycl::id<1> idx,
dpct::accessor<int, dpct::constant, 4> const_array) {
...
... = const_array[x][y][z][w];
...
}is manually adjusted to:
// manually adjusted code:
dpct::constant_memory<int, 3> array(dimX, dimY, dimZ * dimW);
void kernel(sycl::id<1> idx,
dpct::accessor<int, dpct::constant, 3> const_array) {
... = const_array[x][y][w * dimZ + z];
...
}Suggestions to Fix
You may need to rewrite this code.
