◆ _GLIBCXX_CALL

| #define _GLIBCXX_CALL | ( | | __n | ) | | ----------------------- | - | | ----- | - |

Macro to produce log message when entering a function.

Parameters

_GLIBCXX_VERBOSE_LEVEL

Definition at line 44 of file compiletime_settings.h.

◆ _GLIBCXX_PARALLEL_ASSERTIONS

#define _GLIBCXX_PARALLEL_ASSERTIONS

Switch on many _GLIBCXX_PARALLEL_ASSERTions in parallel code. Should be switched on only locally.

Definition at line 61 of file compiletime_settings.h.

◆ _GLIBCXX_RANDOM_SHUFFLE_CONSIDER_L1

#define _GLIBCXX_RANDOM_SHUFFLE_CONSIDER_L1

Switch on many _GLIBCXX_PARALLEL_ASSERTions in parallel code. Consider the size of the L1 cache for gnu_parallel::__parallel_random_shuffle().

Definition at line 68 of file compiletime_settings.h.

◆ _GLIBCXX_RANDOM_SHUFFLE_CONSIDER_TLB

#define _GLIBCXX_RANDOM_SHUFFLE_CONSIDER_TLB

Switch on many _GLIBCXX_PARALLEL_ASSERTions in parallel code. Consider the size of the TLB for gnu_parallel::__parallel_random_shuffle().

Definition at line 74 of file compiletime_settings.h.

◆ _GLIBCXX_SCALE_DOWN_FPU

#define _GLIBCXX_SCALE_DOWN_FPU

Use floating-point scaling instead of modulo for mapping random numbers to a range. This can be faster on certain CPUs.

Definition at line 55 of file compiletime_settings.h.

◆ _GLIBCXX_VERBOSE_LEVEL

#define _GLIBCXX_VERBOSE_LEVEL

Determine verbosity level of the parallel mode. Level 1 prints a message each time a parallel-mode function is entered.
