OpenMP* Options and Parallel Processing Options

This section contains descriptions for compiler options that pertain to offload compilation, OpenMP*, or parallel processing.

• device-math-lib
  Enables or disables certain device libraries. This is a deprecated option that may be removed in a future release.
• fmpc-privatize
  Enables or disables privatization of all static data for the MultiProcessor Computing environment (MPC) unified parallel runtime.
• fopenmp-device-lib
  Enables or disables certain device libraries for an OpenMP* target.
• par-affinity, Qpar-affinity
  Specifies thread affinity.
• par-loops, Qpar-loops
  Lets you select between old or new implementations of parallel loop support.
• par-num-threads, Qpar-num-threads
  Specifies the number of threads to use in a parallel region.
• par-runtime-control, Qpar-runtime-control
  Generates code to perform run-time checks for loops that have symbolic loop bounds.
• par-schedule, Qpar-schedule
  Lets you specify a scheduling algorithm for loop iterations.
• par-threshold, Qpar-threshold
  Sets a threshold for the auto-parallelization of loops.
• parallel, Qparallel
  Tells the auto-parallelizer to generate multithreaded code for loops that can be safely executed in parallel.
• parallel-source-info, Qparallel-source-info
  Enables or disables source location emission when OpenMP* or auto-parallelism code is generated.
• qopenmp, Qopenmp
  Enables the parallelizer to generate multi-threaded code based on OpenMP* directives.
• qopenmp-lib, Qopenmp-lib
  Lets you specify an OpenMP* run-time library to use for linking.
• qopenmp-link
  Controls whether the compiler links to static or dynamic OpenMP* run-time libraries.
• qopenmp-simd, Qopenmp-simd
  Enables or disables OpenMP* SIMD compilation.
• qopenmp-stubs, Qopenmp-stubs
  Enables compilation of OpenMP* programs in sequential mode.
• qopenmp-threadprivate, Qopenmp-threadprivate
  Lets you specify an OpenMP* threadprivate implementation.
• Qpar-adjust-stack
  Tells the compiler to generate code to adjust the stack size for a fiber-based main thread.
