Plenary Talk Abstract
"The development of
an exascale computing capability with
machines capable of executing
O(1018)
operations per second
in the 2018 time frame
will be characterized by
significant and dramatic changes in
computing hardware architecture from
current (2010)
petascale high-performance computers.
From the perspective of computational science,
this will be at least as disruptive as
the transition from vector supercomputing to
parallel supercomputing
that occurred in the 1990s."
This was one of the findings of
a recent workshop on
crosscutting technologies for
exascale computing.
The impact of these architectural changes on
future applications development
for the computational sciences community
can now be anticipated in very general terms.
In this talk,
I will summarize what I believe will be
the major changes in the next decade
for applications development.

"Cycles for Competitiveness:
A View of the Future HPC Landscape"
Slides:
PDF
Talk Abstract
The High Performance Computing (HPC)
market segment
has been trending
towards a $10B/yr scale
with a historical
Compound Annual Growth Rate (CAGR)
greater than Enterprise in general.
Nevertheless,
it continues to be a space
perceived by many/most as a niche.
With analyst data
now supporting HPC as having
20% (or more) share of enterprise,
more strategic attention
is being given to the segment.
Ironically,
it is a segment showing signs of post maturity:
in particular,
the vibrancy of the ecosystem
is on a downward trend,
margins are thin for the
Original Equipment Manufacturers (OEMs),
and procurement complexities
are described as onerous.
Yet new data
derived over the past several years
is showing that there is
a substantial unserved/underserved component
to the market.
This is the space referred to as
the "Missing Middle";
it is those that would use HPC if they could.
It is possible that
a much necessary revitalization
of the HPC segment is at hand.
I will first present
the definition of and data around
the Missing Middle,
covering the scope,
the barriers,
and the "so what".
Then I will describe
the activities of
the Alliance for High Performance
Digital Manufacturing,
a multi-party gathering of entities
having come together
with the expressed intention
of resolving the Missing Middle.
I will also touch on
what is happening around the world
with respect to national competitiveness,
and computational methods for economic growth.
I will finish the talk with
a brief review of
what we call the Digital Supply Chain
as a means to resolving the Missing Middle.
Throughout the presentation,
I will review some of
the latest technologies at Intel.

Talk Abstract
Cyberinfrastructure
is the information technology that,
by definition,
enables scientific inquiry.
High Performance Computing (HPC)
is one of
the key cyberinfrastructure components.
This talk traces the development of
HPC in U.S. academic institutions,
and describes how the
Top 500
list can be used
to measure the investment
that institutions have made in HPC.
In any given Top 500 list,
roughly 25 U.S. academic institutions
have an entry on the Top 500 list,
and this number has been dropping
in recent years.
With support of
a grant from the
National
Science Foundation
to the
University of Arkansas
and
RENCI
(University
of North Carolina at Chapel Hill),
we have studied how investments in HPC
can be shown to be leading indicators of
the research productivity of an institution.
Results show that investment in HPC
can increase
the average NSF funding to an institution
and the average publication production
by a statistically significant amount.
We also discuss the various costs
to invest in HPC,
and suggest supporting factors
in making an HPC investment have a full impact.

Talk Abstract
In the past decade,
the HPC field
has turned to cluster architectures
to achieve performance.
A cluster can deliver
both high peak performance and
excellent price performance.
However,
high peak performance is no guarantee
that an application will run effectively,
much less achieve leading-edge performance.
Cray's focus has always been
to deliver
the world's most powerful HPC solutions
to solve real world problems.
This requires
the ability to scale production applications,
which in turn requires
enhancements to the interconnect,
software and overall system reliability.
This presentation will highlight
technology that Cray has implemented
to achieve the highest level of
sustained performance.
It will also present
examples of where
this highly scalable technology
has been applied
to solve mission critical problems.

Abstract
In recent years,
supercomputing resources have increased
to the point
where it has become possible
to simulate many atmospheric phenomena with
unprecedented detail,
both in regards to
the physical processes
and in the
resolution of the computational grid.
In particular,
simulations of severe

have improved significantly.
This talk will
address
some of the recent research in this area,
focusing on my own work,
and reveal just what is possible
with our current and near-future
computing
capabilities.
Specifically,
I will discuss several challenges that remain
in regards to the physical modeling of
cloud and precipitation processes
within storms,
how these affect
the behavior of
the storm and attendant
tornadoes,
and what still needs to be addressed
as we move toward the goal of
explicit numerical prediction of
severe storms and tornadoes.

"The Use of Supercomputing in
Hurricane Storm Surge and
Hydrodynamic Modeling"
Slides:
available after the Symposium
Abstract
Due to the increase in
supercomputing power and
computing availability,
we can now
more accurately provide evaluations of
hurricanes and the storm surge
or
maximum inundation
associated with these hurricanes
in real-time.
Within this presentation,
we will discuss two applications of the
ADCIRC
(Advanced CIRCulation),
a 2D/3D hydrodynamic model based on the
St.
Venant equations
subject to
the standard
Boussinesq
approximation,
that utilize supercomputing resources
to obtain the simulation results.
Over the 20-year history of ADCIRC,
applications have varied from
predicting the effects of coastal dredging
to developing a tidal database
to estimating the extent of
hurricane storm surge inundation.
When employing supercomputing facilities,
ADCIRC utilizes the
METIS
algorithm
for the domain decomposition
and
MPI
for communication between these domains.
In an effort
to streamline writing of results
and reduce simulation times,
the development team implemented
a new algorithm that utilizes
writer processors to provide
the simulation results.
Recently,
to extend the capabilities of ADCIRC
and
improve its predictive ability
in these and other applications,
the development team has also been
coupling ADCIRC to other models,
either dynamically or one-way,
depending on the physics of the problem.
One application looks at
the 2D ADCIRC
dynamically coupled to
an unstructured version of
the
SWAN
wave model,
and the
HLRDHM
hydrologic model
provides fresh water inflows for
major rivers and tributaries
Initially,
the system is being tested on
the Tar-Neuse-Pamlico Sound basin in
North Carolina;
preliminary results from
Hurricane Isabel
hindcasts will be shown.
Another application looks at
the 3D baroclinic ADCIRC
coupled to the regional
HYCOM
model.
In this presentation,
we will show some preliminary results from
the coupled HYCOM/ADCIRC system in
the Northern Gulf of Mexico.

Talk Abstract
High Throughput Parallel Computing (HTPC)
is a computational paradigm for
an emerging class of applications
where large ensembles (hundreds to thousands)
of modestly parallel (4- to ~64- way) jobs
are used to solve scientific problems
ranging from chemistry, physics, weather and
flood modeling, to general relativity.
Parallel jobs,
in general,
are not very portable,
and as a result are difficult to run
across multiple heterogeneous sites.
In the
Open
Science Grid
(OSG)
framework,
we are currently working on
minimizing these barriers
for an important class of
modestly parallel (4- to ~64- way) jobs
where the parallelism can be executed
on a single multi-core machine.
Some of the first HTPC jobs
began running at the
University
of Oklahoma
(OU)
in 2009.

"Architecting
High Performance Computing Systems
for Fault Tolerance and Reliability"
Slides:
PDF
Talk Abstract
The complex and bleeding-edge nature of
High Performance Computing systems
at times has a negative impact on
their ability to reliably complete
the tasks at hand.
At the same time,
HPC systems generally perform
many hundreds or thousands of independent jobs
simultaneously.
Because of this,
reliability and fault tolerance is
of upmost concern in HPC.
Symmetric multiprocessor HPC systems
are prone to system wide failures
due to single errors in memory,
CPU,
or disk.
With the advent of clustered HPC technology,
the risk of a systemwide failure
can be minimized
if the system is designed correctly.
This talk explores
the key hardware and software components
that are likely to cause system wide failures,
and suggests architecture design techniques
to prevent such failures.

"Infrastructure
as a Service"
(IaaS)
begins to fulfill
the decades-long dream of computer science
for self-configuring and self-healing systems.
For systems developers,
IaaS has created
a new API
where,
instead of allocating memory,
one can allocate entire clusters or networks.
Additionally,
IaaS
truly enables advanced Software Agents (SA),
a development paradigm with a
decades-long dream of
self-configuring and self-healing software.
In this talk,
we will review the basics of IaaS,
discuss its sympathies for Software Agents,
study an active Agent project,
and demonstrate
script utilities and job execution
for cloud operation.

Topic:
"Graphene Sheets-Oil Nanocomposites:
Equilibrium and Transport Properties
from Molecular Simulation"
Slides: available after the Symposium
Talk Abstract
Nanostructured materials
hold unrestricted promise
in material sciences.
It has long been thought that
dispersing nanoparticles in a polymer blend
can enhance
both mechanical and transport properties.
It would be for example desirable
to generate a polymer nanocomposite
with high thermal conductivity.
Such materials could be obtained by
dispersing thermally conductive nanoparticles
within polymers.
Carbon-based nanoparticles
are extremely promising towards these goals,
although the use of carbon nanotubes
is hindered by high resistance
to heat transfer
from the nanotubes to the polymer matrix.
We are interested in
composites in which graphene sheets (GS)
are dispersed within organic oils.
Although pristine GS
agglomerate when dispersed in oils
such as octane, hexane and dodecane,
our equilibrium molecular dynamic simulations
demonstrate that when the GS are functionalized
with short branched hydrocarbons,
they remain well dispersed within the oils.
We are now conducting
equilibrium and non-equilibrium
molecular dynamics simulations
to assess the effective interactions
between GS dispersed in oils,
the self-assembly of GS within oils,
the structure of the fluid surrounding the GS,
and the heat transfer
from a GS to the surrounding matrix.
Our tools are designed to understand
the effect of
GS size,
oils molecular weight
and
molecular architecture
on the GS dispersability
and GS-oil heat transfer rate.
For example,
we detail the formation of
nematic phases for grapheme sheets
in oils at room conditions
as a function of the grapheme volume fraction.
As expected,
the transition from isotropic to nematic phase
occurs at lower grapheme sheet concentrations
as the grapheme sheet size increases.
As a consequence of
the anisotropic molecular-level structure,
a number of macroscopic properties
show anisotropic behavior.
We will discuss here our results,
obtained conducting non-equilibrium
molecular simulations and macroscopic modeling,
for heat conductivity
predicted for graphene-based nanocomposites.

Talk Abstract
Harmonic balance (HB) methods
allow for rapid computation of
time-periodic solutions for
nonlinear dynamical systems.
We present
a filtered
high dimensional harmonic balance (HDHB)
approach,
which operates in the time domain,
and provide a framework for
implementation into
an existing finite element solver.
To demonstrate its capabilities,
the method is used to solve
a set of nonlinear structural dynamics problems
related to the field of flapping flight.
For each example,
the HDHB approach produces
accurate steady-state solutions
orders of magnitude faster than
a traditional time-marching scheme.

Abstract
The
Great
Plains Network
is a regional organization
that crosses state boundaries
and has historically offered one major service,
advanced networking.
GPN faces challenges
in attempting to identify services
and meet needs
across the broader spectrum of
cyberinfrastructure.
Recognizing these challenges,
the GPN Executive Council charged
a GPN CI Advisory Committee (CIAC)
with the tasks of
(a) assessing CI needs in the GPN community
beyond network connectivity,
and
(b) formulating a
"CI plan to make it possible to achieve
[GPN Strategic] objectives and
distinguish the role of GPN
from that of campus and state members
and national organizations
and to partner with these organizations
in ways that complement and advance
the mission of GPN members."
CIAC members were selected from among
the GPN CI community
to be representative of the GPN membership,
and included one outside member.
The committee developed two survey instruments.
The first survey
was designed to identify areas of CI need,
and the second survey
was designed to identify
high priority CI services
that GPN might offer to fill those needs.
This presentation will discuss the process
results and recommendations of
the GPN CI Advisory Committee
These recommendations were unanimously
accepted by the GPN Executive Council.

Talk Abstract
The increase of higher resolution results
generated from HPC analysis
is changing the way
data needs to be managed and retained.
Federally sponsored research
and mandated retention
are further challenging
the landscape of institutes
faced with the need for
preservation of massive amounts of data
for longer periods of time.
The volume of information created
will only increase
as HPC systems become faster;
yet finite restrictions on
budgets, space and manpower
are hard to overcome.
This session will explore
some of the many factors to consider
when faced with such retention requirements.
The technology one might use
depends on many factors.
Knowing the options and
the right questions to ask
will facilitate a choice that will meet
your long term data management requirements.
