The SYCL vector class template (cl::sycl::vec) defined in SYCL 1.2.1 is designed to express data level parallelism inside each work-item. At the same time, cl::sycl::vec is mostly used a short vector container with a set of usefull built-in functions, while parallelism is primarily expressed via work-groups.
This extension introduces an alternative class template (cl::sycl::intel::marray) focused on containing an array of values of fixed size.
