DPC++ Example
int* inputPtr = new int[N]; //host pointer q.submit([&](cl::sycl::handler &cgh) { cgh.parallel_for<class kernel1>(range, [=](cl::sycl::item<1> itemID) { size_t i = itemID.get_id(0); inputPtr[i] = i + 1; }); }).wait();
Possible Correction Strategies
Consider using buffers, shared memory pointers, or device pointers to avoid passing data using host pointers.
