DPC++ Example
cl::sycl::queue queue_1(cl::sycl::cpu_selector{ } ); int* deviceData = (int*)sycl::malloc_device(sizeInBytes, queue_1.get_device(), queue_1.get_context()); memcpy(deviceData, hostData, sizeInBytes); //C++ memcpy function is applied to device pointer // it should be queue_1.memcpy(deviceData, hostData, sizeInBytes);
Possible Correction Strategies
Consider using host-based pointers.
If you use
memcpy
function, replace it with
queue.memcpy
to copy the pointer in the appropriate way.
