Dynamic Analysis and Debugging of Complex Code

TotalView for HPC is a debugging software designed for high-performance computing (HPC) environments. TotalView enables faster fault isolation, improved memory optimization, and dynamic visualization for your high-scale HPC apps. TotalView understands high-scale parallel and multicore applications, with unprecedented control over processes and thread execution and visibility into program states and data.

Reproduce Difficult Problems Quickly

With TotalView for HPC, simultaneous debug many processes and threads in a single window to get complete control over program execution: Running, stepping, and halting line-by-line through code within a single thread or arbitrary groups of processes or threads. Work backwards from failure through reverse debugging, isolating the root cause faster by eliminating repeated restarts of the application. Reproduce difficult problems that occur in concurrent programs that use threads, OpenMP, MPI, CUDA, and GPUs, or coprocessors. Debug autonomous machine applications running on the NVIDIA Jetson AGX Xavier ARM/Volta GPU platform.

No More Memory Leaks or Deadlocks

Memory leaks, deadlocks, and race conditions can be things of the past. Whether an experienced developer or new to the development challenges of multicore or parallel applications, TotalView finds errors quickly, validates prototypes, verifies calculations, and certifies code correctness.

Debugging in C/C++ and Python

Easily analyze and debug multi-language applications written in both Python and C/C++ by seeing an integrated cell stack and easily examining variables in both sets of languages.

Seamless Integration and Support

TotalView works with C, C++, and Fortran applications written for Linux (including the Cray and Blue Gene platforms), Linux PowerLE, UNIX, Mac OS X, and Xeon Phi, and supports OpenMP, MPI, OpenPOWER, OpenACC / CUDA and ARM.
