It is possible to come across some precision issues when running tests that stem from using faster
instructions, which can be circumvented by setting the environment variable `SYCL_PROGRAM_COMPILE_OPTIONS`
as `-cl-fp32-correctly-rounded-divide-sqrt`

The SYCL backend depends on [oneMath](https://github.com/uxlfoundation/oneMath) for Nvidia and AMD devices.
