DPCT1051

Message

SYCL does not support a device property functionally compatible with <property name>. It was migrated to <migrated token>. You may need to adjust the value of <migrated token> for the specific device.

Detailed Help

Not all CUDA* device properties currently have functionally compatible equivalents in SYCL*. If such a property is detected and it is the integer type, it will be migrated to -1. If it is the Boolean type, it will be migrated to false or true depending on the context.

Suggestions to Fix

Review the logic and adjust it manually.

Visit the Migrating to SYCL forum for additional help.

For example, this original CUDA code:

 void foo(cudaDeviceProp deviceProp) {
   size_t a = deviceProp.totalConstMem;
   ...
 }

results in the following migrated SYCL code:

 void foo(dpct::device_info deviceProp) {
   /*
   DPCT1051:0: SYCL does not support a device property functionally compatible
   with totalConstMem. It was migrated to get_global_mem_size. You may need to
   adjust the value of get_global_mem_size for the specific device.
   */
   size_t a = deviceProp.get_global_mem_size();
   ...
 }

which is rewritten to:

 void foo(dpct::device_info deviceProp) {
   size_t a = deviceProp.get_global_mem_size();
   ...
 }
