• High Performance Computing Initiative (HPCI) is
Tech campus-wide initiative to promote HPC and
enable our local R&D community & their
collaborators with our own supercomputing facility.
• Provides various highly computational
infrastructure and several supporting staffs.
HPCI is made possible by Intel equipment
donation and University Research funds.

Knowledge Economy & HPC
• KE - Vague term
• The use of knowledge to produce economic
benefits
• Information and knowledge can be shared, and
actually grow through application.
• Computing/IT helps accelerating KE. Faster &
accurate computing are keys.

What is HPC?
• High Performance Computing – Parallel , Supercomputing
– Achieve the fastest possible computing outcome
– Subdivide a very large job into many pieces
– Enabled by multiple high speed CPUs, networking, software etc – fastest
possible solution
– Technologies that help solving non-trivial tasks including scientific,
engineering, medical, business entertainment and etc.
• Time to insights, Time to discovery, Times to markets
• BTW, HPC is not GRID!!!.

Parallel Programming Concepts
Conventional serial execution
where the problem is represented
as a series of instructions that are
executed by the CPU
Problem
Parallel execution of a problem
involves partitioning of the problem
into multiple executable parts that are
mutually exclusive and collectively
exhaustive represented as a partially
ordered set exhibiting concurrency.

Parallel computing takes advantage of
concurrency to :
• Solve larger problems with less
time
• Save on Wall Clock Time
• Overcoming memory
constraints
•
Utilizing non-local resources

HPC accelerates a product
• FE analysis on 1 CPU
– 1,000,000 elements
– Numerical processing for 1
element = .1 secs
– One computer will take
100,000 secs = 27.7 hrs
• Says 100 CPUs
– .27 hr ~ 16 mins

Avian Flu Pandemic Modeled on a
Supercomputer
•MIDAS (Models of Infectious Disease Agent Study)
program
•The large-scale, stochastic simulation model examines
the nationwide spread of a pandemic influenza virus
strain
•A simulation starts with 2 passengers with contaminated
AF arriving LAX
•The simulation rolls out a city-city and census-tract-level
picture of the spread of infection
•a synthetic population of 281 million people over the
course of 180 days
•It is a very large scale and complex multi-variant

Avian Flu Pandemic (II)
•The results show that advance preparation of a modestly
effective vaccine in large quantities appears to be preferable to
waiting for the development of a well-matched vaccine that
may be too late.
•The simulation models a synthetic population that matches
U.S. census demographics and worker mobility data by
randomly assigning the simulated individuals to households,
workplaces, schools, and the like.
•The models serve as virtual laboratories to study how
infectious diseases and what intervention strategies are more
effective
•Run on the Los Alamos supercomputer known as Pink, a
1,024-node (2,048 processor) LinuxBIOS/Bpro with 2
GB/node.
