least recently used
LRU

This is expensive if one wants to make sure the algorithm always discards the least recently used item.

Blocks or sectors on the media can be tracked in a least recently used queue of some sort.

This requires one bit per pair of cache lines, to indicate which of the two was the least recently used.

In such cases it may be enough to know that in most cases, one of the least recently used items is deleted.

The cart train tends to follow the least recently used of the several winding trails, because the hunting and gathering will be better along it.

The supervisor uses one of a variety of page replacement algorithms such as least recently used to determine which page to free.

All information is stored in memory using the least recently used (LRU) algorithm.

A very simple rule used is called Least recently used (or LRU).

In many CPU caches, a scheme that almost always discards one of the least recently used items is sufficient.

At the back of this list is the least recently used page, and at the front is the most recently used page.

When the table is full, subsequent inserts cause older data to be purged in least recently used (LRU) order.

General implementations of this technique require to keep "age bits" for cache-lines and track the "Least Recently Used" cache-line based on age-bits.

That mostly ended with the development of sophisticated LRU (Least Recently Used) approximations and working set algorithms.

Least Recently Used (LRU): deletes the least recently used items first.

With straightforward Round-robin scheduling, every time a context switch occurs, a process would need to be swapped in (because only the 10 least recently used processes are swapped in).

The not frequently used page-replacement algorithm generates fewer page faults than the least recently used page replacement algorithm when the page table contains null pointer values.

The unified cache is two-way set associative and uses a store-through policy with no reload on a store miss and a least recently used (LRU) replacement policy.

Pseudo-LRU is a cache algorithm created to improve the Least Recently Used (LRU) algorithm.

One popular replacement policy, "least recently used" (LRU), replaces the least recently used entry (see cache algorithm).

LIRS (Low Inter-reference Recency Set) is a page replacement algorithm with an improved performance over LRU (Least Recently Used) and many other newer replacement algorithms.

Most operating systems use some approximation of the least recently used (LRU) page replacement algorithm (the LRU itself cannot be implemented on the current hardware) or a working set-based algorithm.

In either case, new connections were sometimes added to downstream nodes (i.e. the node that answered the request) when requests succeeded, and old nodes were discarded in least recently used order (or something close to it).

This can be emulated in practice with the Least Recently Used policy, which is shown to be within a small constant factor of the offline optimal replacement strategy (Frigo et al., 1999, Sleator and Tarjan, 1985).

The not recently used (NRU), sometimes known as the Least Recently Used (LRU), page replacement algorithm is an algorithm that favours keeping pages in memory that have been recently used.

This instruction loads a 128 bit wide value into a register and marks the corresponding cache block as "least recently used" i.e. as the prime candidate for eviction upon a need to evict a block from its cache set.

Also LRU is especially simple since only one bit needs to be stored for each pair.

It has a better performance than the frequently used LRU cache algorithm.

All information is stored in memory using the least recently used (LRU) algorithm.

A very simple rule used is called Least recently used (or LRU).

The LRU of the two is discarded.

An LRU is usually a sealed unit such as a radio or other auxiliary equipment.

Of those who framed our Constitution the majority of lru intellects came from the South.

That mostly ended with the development of sophisticated LRU approximations and working set algorithms.

According to LRU 1983, a committee of five members had to evaluate the curricula of the candidates.

When the table is full, subsequent inserts cause older data to be purged in least recently used (LRU) order.

The difference is that the data presented is from simulations assuming an LRU replacement policy.

LRU is a marking algorithm, so it is -competitive.

Reform of French universities, including the controversial LRU law.

One popular replacement policy, least-recently used (LRU), replaces the least recently accessed entry.

As loops over large arrays are common, much effort has been put into modifying LRU to work better in such situations.

The combined cache directory is organised in four LRU lists:

One important advantage of the LRU algorithm is that it is amenable to full statistical analysis.

Streamlined cache infrastructure based on a non-blocking LRU algorithm.

In electronics, a sealed piece of replaceable equipment; see line-replaceable unit (LRU).

LRU can refer to:

Many voices claim moreover the abrogation of law LRU on the autonomy of the universities.

The LRU also carries confined space packs which are used when casualties are trapped in a small space such as a mine.

It is common for LRU trays to have standardized connections for rapid mounting, cooling air, power and grounding.

Whenever data must be discarded from the cache, lines are obtained from the LRU end of the probationary segment."

Because of implementation costs, one may consider algorithms (like those that follow) that are similar to LRU, but which offer cheaper implementations.
