Variable Documentation

eraseNDAttributes

volatile int eraseNDAttributes =0

eraseNDAttributes is a global flag the controls whether NDArray::clearAttributes() is called each time a new array is allocated with NDArrayPool->alloc().

The default value is 0, meaning that clearAttributes() is not called. This mode is efficient because it saves lots of allocation/deallocation, and it is fine when the attributes for a driver are set once and not changed. If driver attributes are deleted however, the allocated arrays will still have the old attributes if this flag is 0. Set this flag to force attributes to be removed each time an NDArray is allocated.
