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`

It is possible to come across some precision issues when running tests that stem from using faster
instructions, which can be circumvented by passing the `-fno-fast-math` flag to the compiler.
