The Memory Behavior of the WWW, or The WWW Considered as a Persistent Store
[chapter]
2001
Lecture Notes in Computer Science

Results are linear with the size of the garbage collection Unit (a bunch). ...
This paper presents the performance evaluation of five memory allocation strategies for the PerDiS Persistent Distributed Object store in the context of allocating two different web sites in the store. ...
A complete description of the PerDiS Garbage Collection Algorithm is available in [FS94, FS96] . [BFS98] describe more deeply the implementation. ...

We evaluate these techniques on a prototypical middleware system called PerDiS and show that: (i) the concurrency control mechanisms are well adapted to support long-lived data sharing in local or wide-area ...
In this paper, we describe the design and implementation of concurrency control mechanisms aimed at both reducing the amount of such conflicts and supporting the consistent long-term sharing of data. ...

The algorithm is safe and live; it is not complete, i.e. it collects some distributed cycles of garbage but not necessarily all. In a centralized program, sharing consists simply of using a pointer. ...
The most natural model of persistence is persistence by reachability, managed automatically by a garbage collector (GC). ...
A first prototype of the PerDiS implementation is freely available in http://www.perdis.esprit.ec.org. ...

Experiments show that WTF can qualitatively outperform the industry-standard HDFS distributed filesystem, up to a factor of four in a sorting benchmark, by reducing I/O costs. ...
Microbenchmarks indicate that the new features of WTF impose only a modest overhead on top of the POSIX-compatible API. ...

Using Sinfonia, we implemented two very different and complex applications in a few months: a cluster file system and a group communication service. ...
We propose a new paradigm for building scalable distributed systems. Our approach does not require dealing with message-passing protocols-a major complication in existing distributed systems. ...
We would like to thank Terence Kelly and Jeff Mogul for helpful discussions; our shepherd Sharon Perl, the SOSP reviewers, Xiaozhou Li, and Janet Wiener for many comments that helped us improve the paper ...

This paper describes an approach to providing object persistence in object-oriented programming languages without modifying the run-time system or the language itself. ...
It only uses basic object-oriented programming techniques, and is therefore implementable in any object-oriented programming language. An experimental implementation in Ada 95 is presented. ...
