Optimizing on KNL

Optimizing on KNL (Lab)

Introduction to KNL Tools

Introduction to KNL Tools (Lab)


This advanced manycore training is designed for experienced programmers who have some familiarity with OpenMP,  and is a follow up to the topics covered in “Introduction to Manycore Progamming.” This training will focus on the use of reports and directives to improve vectorization and the implementation of proper memory access. We will also showcase new Intel VTune Amplifier XE capabilities that allow for in-depth memory access analysis and hybrid code profiling. Individuals who have already run on KNL nodes are not required to attend the introductory KNL course prior to attending this course. Hands-on exercises will be executed on the KNL-upgraded Stampede system at the Texas Advanced Computing Center (TACC).

Topics covered in this training:

  • Vectorization, Multiprocessing & Multithreading
  • Understanding Compiler Optimization Reports
  • Using Intel Vtune and Advisor
