gt4py v1 removes the Storage class and allow any __array_interface__ describing object to be bound. Unfortunately, the default cupy allocation used in our model has a bad stride (should have unit stride) leading to performance decrease in the backend.

Potential solution:

  • use gt4py provided allocator (and optimized for the backend)
  • make sure striding in our GPU allocation is unit
