Intel® Fortran Compiler

Consistency of Floating-Point Results using the Intel® Compiler

Why doesn’t my application always give the same answer? Tradeoffs between floating-point accuracy, reproducibility and performance are discussed with examples;recommendations are made for improving reproducibility while limiting the impact on performance. Updated for Intel Composer XE 2013.

  • Floating-point Settings in Worker Threads May Differ from Master Thread for OpenMP, TBB and Intel Cilk Plus

    Worker threads created by OpenMP, Intel Cilk Plus or Intel Threading Building Blocks may have different initial floating-point environments compared to the master thread that spawned them. This can lead to slight differences in floating-point results.
