class Volk(CMakePackage):
"""VOLK is the Vector-Optimized Library of Kernels. It is a
library that contains kernels of hand-written SIMD code for
different mathematical operations. Since each SIMD architecture
can be very different and no compiler has yet come along to handle
vectorization properly or highly efficiently, VOLK approaches the
problem differently.
For each architecture or platform that a developer wishes to
vectorize for, a new proto-kernel is added to VOLK. At runtime,
VOLK will select the correct proto-kernel. In this way, the users
of VOLK call a kernel for performing the operation that is
platform/architecture agnostic. This allows us to write portable
SIMD code."""
