7. 2 November 2015 7 HPCI 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.

8. 2 November 2015 8 LONI and LONI Institute A consortium of Louisiana universities (LSU, Latech, ULL, Tulane, UNO, Southern etc..) One of the most advanced networking and most powerful supercomputing infrastructures –100 Tflops machines, QeenBee 23th in the world –40 Gb/s Lambda network World class research staffs

9. 2 November 2015 9 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.

10. 2 November 2015 10 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!!!.

11. 2 November 2015 11 Parallel Programming Concepts 11 Problem instructions CPU Conventional serial execution where the problem is represented as a series of instructions that are executed by the CPU CPU instructions Task 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 Source from Thomas Sterling’s intro to HPC

12. 2 November 2015 12 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

13. 2 November 2015 13 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

16. 2 November 2015 16 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.
