Unable to work with 4 Dimensional data for batch2d program in dpc++

[Pranathi_R]

Hello team, 

I was trying to run my codes parallelly using dpcpp, but I am facing some issues, my input data is 4 dimension but while using buffer it is not accepting 4D data and throwing following error,  static_assert failed due to requirement '4 >= 1 && 4 <= 3' "range can only be 1, 2, or 3 dimensional." . So, Do you have any alternative to work on 4D data.

Thank you,
Pranathi R

Hi,

Thanks for reaching out to us.

Could you please provide us with a sample reproducer and compiler version?

Also, please provide the OS details so that we can try it from our end.

Thanks & Regards,

Noorjahan.

There are a number of ways one can process 4 dimensional data even despite buffers being limited to three dimensions.

It all is a matter of understanding what you are trying to do, and designing an algorithm which achieves this.

For example, you could store all your data in a 1 dimensional array, but index it in a way to simulate four dimensions.

More details on that here: 4d-position-from-1d-index 

Another way is to store the data in a 1D list of 4D tuples.

I have provided an example of this using DPC++ in the attached file.
