How could we use struct including vector or array

jimbook_ — Sun, 07 May 2023 09:05:10 GMT

struct obj {
  int* arr;
  int size;
};

struct obj {
  vector<int> arr;
  int size;
};

I want to build a struct like above, but sycl may not allow these struct. The first struct contains a point, So these data to which the pointer points cannot be copied to device. The second struct contains a vector, but at code of device I am not able to get data using subscripts.
The quesition is how can I build a struct with same functional which can be used on the device.

Hi,

Thanks for posting in Intel Communities.

>>>The quesition is how can I build a struct with same functional which can be used on the device.

We can build structures with both array pointer member and vector member in SYCL code which can be used on device.

We've tried a sample code using structures with both array pointer and vector members and we received expected outputs.

Please refer to the attached zip file for the sample codes that we have tried.

Also please refer to the below screenshots for the results.

For structure with pointer array member:

For structure with vector member:
