About:
OTF2 is a generic trace file format for recording performance events. It provides a library for writing and reading trace data, enabling efficient analysis of parallel applications. Its main value is in standardizing performance data exchange for HPC tools.
Key Features:
  • High-performance I/O for large-scale trace data
  • Supports event and location-centric recording
  • Provides a portable API for C, C++, and Fortran
  • Includes an open-source reference implementation
Use Cases:
  • Recording performance data from parallel HPC applications
  • Developing custom performance analysis tools
  • Exchanging trace data between different analysis frameworks
Alternatives:
  • HPCtrace – OTF2 is a newer, more efficient standard that largely supersedes HPCtrace for event recording.
  • Intel Trace Analyzer and Collector – OTF2 is an open, vendor-neutral standard, whereas Intel's tool is proprietary and tied to their ecosystem.
