GPU version of interface-discontinuity-based wavefield injection (pull request 1706).

The script to run the small example is also updated to use the GPU version. Currently only forward simulation; adjoint simulation and kernel calculation will come soon.

I got an error during "test intel on ubuntu-22.04", and it looks like it's due to compilation error at line 797 of src/shared/read_parameter_file.f90. I couldn't understand the error so far, and no changes have been made near that line (the only change to this file is at line 1079. If I could get some help on what is potentially going wrong that would be great! Thanks!

[danielpeter]

no worries, the error seems to be some internal compiler hiccup with the Intel compiler (happening from time to time).

thanks a lot for the GPU support :)

[tianshi-liu]

Great! Thanks a lot for checking.
