Debug applications running in your HPC environments faster with TotalView, by taking advantage of its abilities to:
- Support more than 20 different MPI implementations.
- Debug multithreaded applications with pthreads, OpenMP, and TBB.
- Easily establish interactive debugging sessions within your cluster — including through batch submission systems.
- Provide visualizations of program data and variables.
- Define how aggregate data in displayed, so you can see custom data structures in simpler forms.
- Debug programs using the CUDA and/or OpenACC models.
- Perform advanced memory debugging, including memory leaks and errors.
Speed issue resolution in HPC code by using the reverse debugging capability in TotalView to:
- Work back from a failure, error, or crash to its root cause.
- Record and replay:
- Heap memory usage.
- Process file and network I/O.
- Thread context switches.
- Multithreaded applications.
- MPI parallel applications.
- Distributed applications.
- Network applications.
- Step forward and backward by function, line, and instruction.
- Support continuous integration, collaboration, and code-learning by recording code.
- Eliminate restarting your program repeatedly with different breakpoints.
- Learn new code and deliver enhancements quicker.
Find memory leaks and buffer overruns with TotalView's scalable memory-debugging technology:
- Easily find memory leaks and understand heap usage.
- Detect malloc/free, new/delete API misuse.
- Detect buffer overruns.
- Share memory debugging data with colleagues through data files and HTML reports.
- Compare memory results between sessions to verify elimination of leaks.
- Save time and money with low overhead technology that does not require recompilation or instrumentation.
When you deploy TotalView on a host machine, you can debug jobs running on compute nodes from a client running TotalView using the Remote Display Client feature. With it, you can:
- Receive an alert when your application starts running on remote infrastructure.
- Run remote debugging sessions using a client device — even if it does not have a TotalView license.
- Submit batch jobs to SLURM, PBS Pro, and Load Leveler batch-queuing systems.
You can debug applications written in one or more of the following languages, using TotalView:
- C and C++
- Mixed-language applications written in Python and C/C++
The applications you debug using TotalView can run on the following operating systems:
- Linux including Cray Linux Environment (CLE) and PowerLE
- UNIX including AIX and Solaris
You can use TotalView to debug and optimize code for laptops, workstations, servers, clusters, and supercomputers with the following processors:
- ARM (aarch64)
- Intel/AMD (x86-64, x86)
- NVIDIA GPUs on Linux x86-64, Linux ARM64, and Linux PowerLE (Power9)
- NVIDIA Jetson AGX Xavier
