Debugging numerical simulations on accelerated architectures: TotalView for OpenPOWER, CUDA, and OpenMP

This talk from ScicomP 2015 helps you debug numerical simulations better by reviewing best debugging practices for CUDA and OpenACC-accelerated applications and discussing the development of OpenMP-specific tracing and debugging interfaces (including the OMPD interface for performance analysis). 
 

This talk also reviews the collaboration between Lawrence Livermore National Laboratory (LLNL) and Rogue Wave Software towards the TotalView debugger supporting the OpenPOWER stack on LLNL's future Sierra system. TotalView, which has long been the gold standard for parallel debugging on the iDataPlex, Linux Power, and Blue Gene architectures, is being ported to little endian Linux on Power8 and Power9.

Presenters: Chris Gottbrath, Principal Product Manager and Dean Stewart, Sales Engineer, Rogue Wave Software
