1 Advanced High Performance Computing CSCI 580 2:00 pm - 3:15 pm Tue & Thu Marquez Hall 322 Timothy H. Kaiser, Ph.D. tkaiser@mines.edu CTLM 241A 1
2 Two Similar Classes this fall MATH 440/540 - PARALLEL SCIENTIFIC COMPUTING CSCI Advanced High Performance Computing 2
3 Alternative Class MATH 440/540 - PARALLEL SCIENTIFIC COMPUTING Class 2:00 pm - 2:50 pm MWF Meyer Hall 363 This course is designed to facilitate students learning of parallel programming techniques to efficiently simulate various complex processes modeled by mathematical equations using multiple and multi-core processors. Emphasis will be placed on the implementation of various scientific computing algorithms in FORTRAN/C/C++ using MPI and OpenMP. Prerequisite: MATH407, CSCI407, or consent of instructor. 3 hours lecture, 3 semester hours. 3
4 Description Advanced High Performance Computing CSCI 580 This course provides students with knowledge of the fundamental concepts of high performance computing as well as hands-on experience with the core technology in the field. The objective of this class is to understand how to achieve high performance on a wide range of computational platforms. Topics will include sequential computers including memory hierarchies, shared memory computers and multicore, distributed memory computers, graphical processing units (GPUs), cloud and grid computing, threads, OpenMP, message passing (MPI), CUDA (for GPUs), parallel file systems, and scientific applications. 3 hours lecture; 3 semester hours. 4
5 to Ganesh After our discussion this summer I thought about my content. If you look at the official descriptions of the two classes there is a lot of overlap. I have decided to put more emphasis on daily problem solving, that is after you have an application running, how do you make it work better, or the old line "My program worked last week why doesn't work today?" I will cover the stuff in the course description quickly then my goal will be to teach people how to do my job. The optimization and debugging portions of my class will hit BGQ and Phi very hard. 5
6 Teach you to do my job! 6

9 From our Text... Employing high performance computing (HPC) as a research tool demands at least a basic understanding of the hardware concepts and software issues involved. This is already true when only using turnkey application software, but it becomes essential if code development is required. The new PhD student is all too often left alone with the steep learning curve... Georg Hager;Gerhard Wellein. Introduction to High Performance Computing for Scientists and Engineers (Kindle Locations ). Kindle Edition. 9
10 Additional Topics Libraries for HPC, threaded and MPI based Profiling Optimization (Fix my dissertation code) Debugging Advanced batch scripting Scientific visualization Intel MIC Proposal Writing Proposal Review CSM's new machine architecture Utilities for HPC ssh - keys and usage Building Applications Some administration CS is Science 10
11 Expectations Grad level CS class with content that should be reasonable for all CSM grad students, including CS students Programming ability in C, C++, or Fortran Domain knowledge (non CS students may have advantage) Future assignments will be determined from the first assignment Your experience Simple serial program Profiling Debugging Parallelize serial program Program Install Scripting 11
