TotalView for HPC

Faster fault isolation, improved memory optimization, and dynamic visualization for your high-scale HPC apps

Understand high-scale parallel and multicore applications, with unprecedented control over processes and thread execution and visibility into program states and data.

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, GPUs, or coprocessors.

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.

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.

“We rely on TotalView for all of our parallel debugging needs. Its scalability, multi-language support, and built-in debugger make it an indispensable tool for us.”
