Vampir meets ISC 2023

We would like to welcome you at ISC High Performance 2023 in the city of Hamburg! Our performance visualizer for parallel programs provides graphical visualization of massively parallel applications. We welcome you at our booth J903 from May 21 to May 25 where we showcase the latest version of our tool suite. Additionally, you can engage with our experts in various activities of the ISC 2023 program.

At ISC 2023 we unveil Vampir 10.3 that provides support for visualizing Chrome Traces produced by AI frameworks like PyTorch or TensorFlow. Loading large traces in common tools like Chrome or Perfetto is limited by the memory resources available to the browser. The distributed architecture of Vampir allows users to load even large traces into memory for visualization. Other new features include new charts for message and I/O summary timelines.

Score-P is the primary code instrumentation and run-time measurement framework for Vampir 10, and also works natively with Scalasca, TAU, and Periscope.

It supports an extensive set of events such as function and library calls, communication events, and hardware counters. Score-P supports various instrumentation methods, including instrumentation at source level and at compile/link time. Recently, experimental support for sampling has been added. Vampir and Score-P provide a performance tool framework with special focus on highly-parallel applications. Performance data is collected from multi-process (MPI, SHMEM), thread-parallel (OpenMP, Pthreads), as well as accelerator-based paradigms (CUDA, HIP, OpenCL, OpenACC).
