#define _GLIBCXX_ASSERTIONS

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

#define _GLIBCXX_MULTIWAY_MERGESORT_COPY_LAST

First copy the data, sort it locally, and merge it back (0); or copy it back after everything is done (1).

Recommendation: 0

#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 74 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 80 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 61 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.
