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.
