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.
