memory_full_cache module

Caching module to avoid multiple evaluations of a discipline

class gemseo.caches.memory_full_cache.MemoryFullCache(tolerance=0.0, name=None)

Bases: gemseo.core.cache.AbstractFullCache

Cache using memory to cache all data.

Initialize a dictionary to cache data.

Initialize cache tolerance. By default, don’t use approximate cache. It is up to the user to choose to optimize CPU time with this or not could be something like 2 * finfo(float).eps

Parameters

• tolerance (float) – Tolerance that defines if two input vectors are equal and cached data shall be returned. If 0, no approximation is made. Default: 0.

• name (str) – Name of the cache.

Examples

>>> from gemseo.caches.memory_full_cache import MemoryFullCache
>>> cache = MemoryFullCache()

clear()

Clear the cache

Examples

>>> from gemseo.caches.memory_full_cache import MemoryFullCache
>>> from numpy import array
>>> cache = MemoryFullCache()
>>> for index in range(5):
>>>     data = {'x': array([1.])*index, 'y': array([.2])*index}
>>>     cache.cache_outputs(data, ['x'], data, ['y'])
>>> cache.get_length()
5
>>> cache.clear()
>>> cache.get_length()
0

property copy

Copy cache.
