Intel Xeon Phi Workshop June 4 2015 800 AM - 500 PM BEC ROOM 1700

Programming And Optimization With Intel Xeon Phi Coprocessors

Intel Corporation, LSU Center for Computation & Technology and HPC@LSU will host a one day Intel Xeon Phi workshop on June 4th, 2015 in Business Education Complex, Room 1700 at LSU, Baton Rouge, LA.


Colfax Developer Training (CDT) is an in-depth intensive course on efficient parallel programming of Intel Xeon family processors and Intel Xeon Phi coprocessors.

The 1-day labs course (CDT 102) features hands-on exercises on the available programming models and best optimization practices for the Intel many-core platform, and on the usage of the Intel software development and diagnostic tools. The pre-requisite for this class is is the one-day seminar CDT 101.

9 am to 4 pm: Hands-on sessions
-Offload and Native: "Hello World" to complex; using MPI.
-Performance Analysis: VTune.
-Case Study: all aspects of tuning in the N-body calculation.
-Optimization I: strip-mining for vectorization, parallel reduction.
-Optimization II: loop tiling, thread affinity.

Intel Xeon Phi coprocessors, featuring the Intel Many Integrated Core (MIC) architecture, are novel many-core computing accelerators for highly parallel applications, capable of delivering greater performance per system and per watt than general-purpose CPUs. Unlike GPGPUs, they support traditional HPC programming frameworks, including OpenMP and MPI, and require the same software optimization methods as multi-core CPUs.
