#define _GLIBCXX_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.

#define _GLIBCXX_CALL

(

__n

)

Macro to produce log message when entering a function.

Parameters:

__n	Input size.

#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.

#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.

#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.

#define _GLIBCXX_VERBOSE_LEVEL

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