Function Documentation

void* invt_allocate_aux (  size_t  nbytes  )

Allocate nbytes of memory, throwing an exception in case of failure. Definition at line 515 of file AllocAux.C. References g_alloc, g_alloc_mutex, and GVX_MUTEX_LOCK. Referenced by invt_allocate().

void invt_allocation_allow_caching (  bool  on  )

Turn on/off caching of memory blocks of commonly-used sizes. Definition at line 533 of file AllocAux.C. References g_alloc, g_alloc_mutex, and GVX_MUTEX_LOCK. Referenced by ModelManager::paramChanged().

void invt_allocation_debug_print (  bool  print  )

Turn on/off memory-allocation debugging statements. If on, each invt_allocate() and invt_deallocate() call will print some stats about the memory block being currently allocated/deallocated, as well as some general stats about the total amount of memory allocated and the amount of memory currently in use Definition at line 539 of file AllocAux.C. References g_alloc, g_alloc_mutex, and GVX_MUTEX_LOCK.

void invt_allocation_release_free_mem (   )

Released any cached free memory blocks (e.g. to conserve memory). Definition at line 527 of file AllocAux.C. References g_alloc, g_alloc_mutex, and GVX_MUTEX_LOCK. Referenced by TrainingSet::load(), and TrainingSet::loadRebalanced().

void invt_allocation_set_stats_units (  const size_t  units  )

Set the units to be used by default in invt_allocation_show_stats(). Definition at line 553 of file AllocAux.C. References g_stats_units. Referenced by InputFrameSeries::Impl::readFrame().

void invt_allocation_show_stats (  int  verbosity = 0, const char *  pfx = 0, const size_t  units = 0 )

Print current stats for whatever memory allocator is in use. Parameters: verbosity  If greater than 0, will request additional stats to be displayed pfx  If non-null, will be printed at the beginning of each stats line. units  If non-zero, allocated memory blocks will be listed as multiples of this number of bytes; otherwise memory blocks will be listed as multiples of the units specified in the most recent call to invt_allocation_set_stats_units(). Definition at line 545 of file AllocAux.C. References g_alloc, g_alloc_mutex, g_stats_units, and GVX_MUTEX_LOCK. Referenced by submain().

void invt_deallocate_aux (  void *  mem  )

Deallocate the given memory region. Definition at line 521 of file AllocAux.C. References g_alloc, g_alloc_mutex, and GVX_MUTEX_LOCK. Referenced by invt_deallocate().
