Although directory-based cache-coherence protocols are the best choice when designing chip multiprocessors with tens of cores on-chip, the memory overhead introduced by the directory structure may not scale gracefully with the number of cores. Many approaches aimed at improving the scalability of directories have been proposed. However, they do not bring perfect scalability and usually reduce t...

This document defines a MIME Content-Type for holding directory information. The definition is independent of any particular directory service or protocol. The text/directory Content-Type is defined for holding a variety of directory information, for example, name, or email address, or logo. The text/directory Content-Type can also be used as the root body part in a multipart/related ContentTyp...

The YPA is a directory enquiry system that allows a user to access addresses and other advertiser information in a classified directory. BT’s Yellow Pages provide an example of a classified directory with which this work would be useful.

With the growth of the Internet, directory softwares have recently proliferated. The Lightweight Directory Access Protocol (LDAPv3 [18]) is the standard, proposed by the Internet Engineering Task Force (IETF [9]) for modelling and querying network directory information, as well as accessing network directory services. More recently, several extensions have been proposed to the directory model t...

We present a new dynamic hashing scheme for disk-based databases, called Multi-Directory Hashing (MDH). MDH uses multiple hash directories to access a file. The size of each hash directory grows dynamically with the file size. The advantages of MDH are enhanced concurrency, improved bucket utilization and smaller total directory size than single-directory hashing. The expected utilization of MD...
