oneapi::mkl::vm::status::success	VM function execution completed successfully
oneapi::mkl::vm::status::not_defined	VM status not defined
Warnings
oneapi::mkl::vm::status::accuracy_warning	VM function execution completed successfully in a different accuracy mode
Computational status codes
oneapi::mkl::vm::status::errdom	Values are out of a range of definition producing invalid (QNaN) result
oneapi::mkl::vm::status::sing	Values cause divide-by-zero (singularity) computational errors and produce and invalid (QNaN or Inf) result
oneapi::mkl::vm::status::overflow	An overflow happened during the calculation process
oneapi::mkl::vm::status::underflow	An underflow happened during the calculation process
