Abstract—Data-parallel programming languages are an important component
in today's parallel computing landscape. Among those are domain-
specific languages like shading languages in graphics (HLSL, GLSL,
RenderMan, etc.) and "general-purpose" languages like CUDA or OpenCL.
Current implementations of those languages on CPUs solely rely on multi-
threading to implement parallelism and ignore the additional intra-core
parallelism provided by the SIMD instruction set of those processors
(like Intel's SSE and the upcoming AVX or Larrabee instruction sets).
In this paper, we discuss several aspects of implementing data-parallel
languages on machines with SIMD instruction sets. Our main contribution
is a language- and platform-independent code transformation that
performs whole-function vectorization on low-level intermediate code
given by a control flow graph in SSA form.
We evaluate our technique in two scenarios: First, incorporated in a
compiler for a domain-specific language used in real-time ray tracing.
Second, in a stand-alone OpenCL driver. We observe average speedup
factors of 3.9 for the ray tracer and factors between 0.6 and 5.2 for
different OpenCL kernels.

While a number of different shading languages have been developed,
their efficient integration into an existing renderer is notoriously
difficult, often boiling down to implementing an entire compiler
toolchain for each language. Furthermore, no shading language is
broadly supported across the variety of rendering systems.
AnySL attacks this issue from multiple directions: We compile shaders
from different languages into a common, portable representation, which
uses subroutine threaded code: Every language operator is translated to
a function call. Thus, the compiled shader is generic with respect to
the used types and operators.
The key component of our system is an embedded compiler that
instantiates this generic code in terms of the renderer's native types
and operations. It allows for flexible code transformations to match
the internal structure of the renderer and eliminates all overhead due
to the subroutine threaded code. For SIMD architectures we
automatically perform vectorization of scalar shaders which speeds up
rendering by a factor of 3.9 on average on SSE. The results are highly
optimized, parallel shaders that operate directly on the internal data
structures of a renderer. We show that both traditional shading
languages such as RenderMan, but also C/C++-based shading languages,
can be fully supported and deliver high performance across different
CPU renderers.

The polyhedral model provides a powerful mathematical abstraction to
enable effective optimization of loop nests with respect to a given
optimization goal, e.g., exploiting parallelism. Unexploited
reduction properties are a frequent reason for polyhedral optimizers
to assume parallelism prohibiting dependences. To our knowledge, no
polyhedral loop optimizer available in any production compiler
provides support for reductions. In this paper, we show that
leveraging the parallelism of reductions can lead to a significant
performance increase. We give a precise, dependence based, definition
of reductions and discuss ways to extend polyhedral optimization to
exploit the associativity and commutativity of reduction
computations. We have implemented a reduction-enabled scheduling
approach in the Polly polyhedral optimizer and evaluate it on the
standard Polybench 3.2 benchmark suite. We were able to detect and
model all 52 arithmetic reductions and achieve speedups up to 2.21×
on a quad core machine by exploiting the multidimensional reduction
in the BiCG benchmark.

The polyhedral model is only applicable to code regions that form static
control parts (SCoPs) or slight extensions thereof. To apply polyhedral
techniques to a piece of code, the compiler usually checks, by static
analysis, whether all SCoP conditions are fulfilled. However, in many
codes, the compiler fails to verify that this is the case. In this paper
we investigate the rejection causes as reported by Polly, the polyhedral
optimizer of a state-of-the-art compiler. We show that many rejections
follow from the conservative overapproximation of the employed static
analyses. In SPolly, a speculative extension of Polly, we employ the
knowledge of runtime features to supersede this overapproximation. All
speculatively generated variants form valid SCoPs and are optimizable by
the facilities of Polly. Our evaluation shows that SPolly is able to
effectively widen the applicability of polyhedral optimization. On the
SPEC 2000 suite, the number of optimizable code regions is increased by
131 percent. In 10 out of the 31 benchmarks of the PolyBench suite,
SPolly achieves speedups of up to 11-fold as compared to plain Polly.
