FlowFPX

FlowFPX is a toolkit for systematically debugging floating-point exceptions.

Components:

• TrackedFloats.jl for logging and fuzzing exceptional values in Julia code: https://github.com/utahplt/TrackedFloats.jl
  • Examples: https://github.com/utahplt/FloatTrackerExamples
• Coalesced Stack-Trace Graphs (CSTGs) for summarizing logs: https://github.com/utahplt/CSTG
• GPU-FPX for logging exceptions in NVIDIA GPU kernels: https://github.com/LLNL/GPU-FPX
