S0407 A High Level Programming Environment for
Accelerated Computing
One of the critical hurdles for the widespread adoption of accelerated
computing in HPC is programming difficulty. Users need a simple
programming model that is portable and is not significantly different
from the approaches used on current multi-core x86 processors. In
this talk I will present Cray’s strategy to accelerator programming,
which is based on a high level programming environment with tightly
coupled compilers, libraries, and tools. Ease of use is possible with
compiler making it feasible for users to write applications in Fortran,
C, C++, tools to help users port and optimize for accelerators, and
auto-tuned scientific libraries.

S0413 Delivering 3D Professional Graphics from the
Cloud with Citrix XenDesktop
Recent technological advances have made it practical to deliver
3D professional graphics applications from the Cloud (private or
public) with a high quality user experience and at an attractive
cost. Organizations can keep their intellectual property safe in the
data center since only fully-rendered screen images are sent over
the network. Users in remote locations no longer have to wait for
large file transfers. And they can access 3D models from a wide
variety of devices, including iPads and Android tablets. Learn how
Citrix XenDesktop, XenServer and Receiver technologies have
made all of this a reality for many organizations today.

S0436 Integrated GPU Acceleration With Real Time
Visualization Of Terabyte Data
Computation and visualization doesn’t necessarily have to act as
two separate entities. This talk explains the integration of real-time
compute with real-time visualization. Industry and academia have
provided attractive solutions for compiler-directive optimized code
for computations. To support cases that involves massive yet ad-hoc
data I/O and computation with interactive visualization, Hue
developed a different model which bridges the gap between
“complete system rewrite” and “compiler directive optimized code”.
The talk explains how highly optimized data I/O mechanisms
coupled with predefined input and output definitions for kernels
provide excellent scalability and interactivity during runtime.

S0611 Edge-Aware Shaders for Real-Time
Computer Graphics
The most common approach in rendering is to define behavior at a
point in terms of material properties and incident illumination.
That approach works well when the geometry and material
properties are well-known, and the light physics are simulated
accurately. We present a technique to help situations where the
model and/or physics is incomplete. This technique augments
shaders with information about nearby edges, such as corners
and boundaries between materials, and makes it natural to add
richness procedurally near these visually critical regions.

S0620 VSIPL++: A High-Level Programming Model
for Productivity and Performance (Presented by
Mentor Graphics)
Learn how VSIPL++ can improve your productivity and provide
software portability, without sacrificing performance. We will
describe how VSIPL++’s open-standard high-level programming
model addresses the challenges of writing high-performance
embedded software on GP-GPUs and other heterogeneous
hardware, using advanced C++ techniques and data abstraction –
and how we make this work in the real world. We will also present
a comparison of performance results from various configurations
of CPU and GP-GPU processing engines for a signal processing
application developed using VSIPL++.

Graphics Corporation)

S0625 S3D Direct Numerical Simulation - Preparations
for the 10-100PF Era
The evolution of supercomputing into the mid-petaflop era has
been typified by heterogenous compute nodes with the majority of
the compute capability delivered by a large number of lightweight
cores. In order to prepare for the extension of this trend, the DNS
code S3D has been retooled in anticipation of a target architecture
offering 10s of thousands of heterogeneous nodes containing many
X86 cores as well as GPU derived accelerators. Movement of outer
loops to the highest level in the code facilitates hybrid MPI-OpenMP
performance and an elegant path to accelerated kernels using
OpenACC. It is anticipated that relevant scientific simulations at this
scale will have a per-node footprint that can be contained entirely
on the accelerator, so provision is made to maintain primary
solution variables in accelerator memory with specific regions
moved to the CPU for inter-node communication and workload
balancing. With the current performance it is estimated that the
new code will make it possible to meet early science goals with the
full build-out of the anticipated Titan system as well as provide a
platform to transition into the exascale software research space.
