NERSCPowering Scientific Discovery for 50 Years

Debugging Challenging Memory and GPU Problems with TotalView, May 13, 2024

May 13, 2024

On Monday, May 13, 2024, NERSC is hosting a training event on effectively using TotalView to debug challenging memory and NVIDIA GPU problems.  TotalView from Perforce Software is a parallel debugger for complex C, C++, Fortran, and CUDA applications. Using live demonstrations running on Perlmutter, you’ll learn how to:

  • Leverage TotalView’s powerful memory debugging technology to find memory leaks, detect dangling pointers, uncover buffer overwrites, and validate use of heap-based memory APIs
  • Debug CUDA, OpenMP, and OpenACC code running on NVIDIA GPUs


Time (PDT/UTC-7) Topic Presenters
9-9:10 am Introduction  
9:10-10:00 am Memory Debugging Larry Edelstein, John DelSignore (Perforce Software)
