Talk Abstract
Research and progress in
high performance computing
often require
multidisciplinary and interdisciplinary efforts
to take advantage of
model and simulation approaches.
In this talk,
I will explore some ideas
that demonstrate how
the thinking in one science
can influence a simulation in another.
We'll draw examples from biology and physics,
primarily,
to show what we can learn from each other.

Abstract
This research studies
the behavior and performance of
two and widely used
computationally intensive kernels
in
two of the most popular
many-core programming models,
CUDA and OpenACC.
This research also shows that
the nature of the problem
plays a crucial role
in determining what many-core model
will provide the highest performance.
The first kernel under study is
a
Fast
Fourier Transform
(FFT),
which samples a signal over
a period of time
and
divides it into its frequency components,
computing the
Discrete
Discrete Fourier Transform
(DFT)
of a sequence.
The second kernel is
Matrix Multiplication,
which is a critical routine in
Mathematics,
Artificial Intelligence,
Machine Learning
and
Deep Learning.

Talk Abstract
For the past 25 years,
the State of Oklahoma has benefitted from
having a network of
120 surface weather observing stations,
known as the
Oklahoma
Mesonet,
deployed across the state.
It has been proposed that
a fleet of
automated Small Unmanned Aerial Systems (sUAS),
also known as drones,
could be
deployed at many,
or all,
of the Mesonet sites,
to make vertical profile
measurements of
temperature,
humidity
and
pressure
in the lower atmosphere,
thus creating a 3D Mesonet.
There are technical and policy impediments to
deploying such a network today,
but through the use of an
Observing System
Simulation Experiment,
or OSSE,
we can investigate the ability of such a
network
to improve the numerical weather forecasts
for critical severe weather events.
Here we present the results of a few tests
that were performed by
recently-graduated MS student
Andrew Moore,
utilizing
OSCER's Schooner supercomputer.

"Making an HPC Storage Procurement Decision
Informed by HPC"
Slides:

Abstract
Laureate Institute for Brain Research
faces yet another storage challenge in 2018.
This challenge is created by
the existence of
a sizable amount (160 TB) of
scientific data
made up of files
ranging in size between
20 KB and 80 KB
that need to be available for analysis.
While this data can be stored in
our 5 PB nearline storage environment
made up of HDDs and Ceph,
performance for analysis
is not what our users would prefer.
Furthermore,
LIBR operates
a VMware environment
consisting of approximately 150 guests
consuming 50 TB of storage.
Both scenarios would benefit greatly from
a flash storage offering.
Unfortunately,
200+ TB of flash storage is not a cheap ask.
As such,
LIBR embarked on
an effort to add flash storage to
its existing Ceph storage environment.
Because Ceph generally is not
a commercial product with
standardized hardware
and
known performance characteristics,
LIBR must determine
how its cluster will perform
with specific disks under specific workloads.
This talk covers
how LIBR is leveraging its HPC environment
to analyze
over 20 billion benchmark data-points
created with a battery of tests
against each candidate model of SSD
being evaluated in this project.

Talk Abstract:
Deep Learning (DL)

with AI-fueled breakthroughs
being announced almost on a daily basis.
Many of the algorithms behind DL
are several decades old,
and advances in
affordable hardware technologies,
coupled with copious amounts of usable data,
has led to the recent resurgence in interest.
Even though we're still in the early days of
DL as a technology,
researchers are already running into
hurdles of scalability.
For the practitioners in HPC,
this is nothing new,
where the argument of scale-up vs scale-out
has played out
has seen a clear winner
dictated more by practicality
rather than technology.
Is Deep Learning at a similar juncture,
and what can our experience with HPC
tell us about where it's headed?

"Disco: A Distributed High-Performance
Assembler for Large Metagenomes"
Slides:
available after the Symposium
Talk Abstract
A distributed,
iterative,
scalable co-assembler,
Disco,
was developed to assemble
large real-world metagenomes
from up to billions of
Illumina
reads.
Disco was parallelized using
a hybrid architecture that integrated
shared-memory multi-threading,
point-to-point message passing,
and remote memory access.
Metagenome assembly and scaffolding
were performed
using an iterative overlap graph approach.
Disco was compared with
metaSPAdes,
ABySS,
MEGAHIT,
MetaVelvet,
and
Ray Meta,
using three mock communities
spanning a range of complexities.
The assembly quality of Disco
was comparable to
the best of these assemblers,
based on
completeness,
accuracy,
and contiguity of their assemblies
of these mock communities.
The computational performance of Disco
was evaluated on hardware
from single computers
to high-performance-computing clusters.
On single computers,
Disco was more computationally efficient than
metaSPAdes,
ABySS,
MEGAHIT,
and
MetaVelvet.
On computer clusters,
Disco also scaled better than
Ray Meta,
ABySS
and
HipMer.
These advantages of Disco
enabled high-quality assembly of
real-world metagenomes
from deep sequencing of
complex communities in
wetland sediments and human gut.
Disco is easy to use and freely available
here.
Biography
Dr. Pan recently joined the
School
of Computer Science
and the
Department
of Microbiology & Plant Biology
at the
University
of Oklahoma.
he was a senior research scientist in the
Computer
Science and Mathematics Division
at
Oak
Ridge National Laboratory.
The research in Dr. Pan's lab
is focused on using
high-performance computing,
machine learning,
and network analysis
to analyze big -omics data
from microbial communities
and eukaryotic organisms.
He has developed scalable algorithms
to assemble and annotate large metagenomes
and
process mass spectrometry data
from proteomics and metabolomics.
These informatics tools
have enabled many biological discoveries
regarding nutrient cycling in
soil and metabolic interactions
between plants and
their rhizosphere communities.

Topic:
"Coarse-Grained Computations for
Understanding Nanofluids"
Slides:
available after the Symposium
Talk Abstract
Coarse-grained computations using
Dissipative
Particle Dynamics
(DPD)
techniques
can provide insights to
complex physical processes,
where molecular level simulations
are too cumbersome
and
macroscopic simulations can miss
the nuances of the physics occurring at
the molecular level.
We use DPD techniques
to simulate nanofluidic behavior
on OSCER machines.
In this talk,
we will present
a protocol for the determination of
model parameters for DPD computations,
and recent results about
the behavior of carbon nanotubes
with surfactants in aqueous suspensions
and
at the oil-water interface.
This is important in several application areas,
including
oil recovery
and
industrial separation processes.
