A Tcl Implementation in Java: Java Command Language, is a version of the Tcl [1] scripting language for the Java [2] environment. Jacl is designed to be a universal scripting language for Java: the Jacl interpreter is written completely in Java and can run on any Java Virtual Machine. Jacl can be used to create Web content or to control Java applications

A Performance Study of Sequential I/O on Windows NT 4: Large-scale database, data mining, and multimedia applications require large, sequential transfers and have bandwidth as a key requirement. This paper investigates the performance of reading and writing large sequential files using the Windows NT� 4.0 File System.

A Frequently Redundant Array of Independent Disks: Disk arrays are commonly designed to ensure that stored data will always be able to withstand a disk failure, but meeting this goal comes at a significant cost in performance. We show that this is unnecessary. By trading away a fraction of the enormous reliability provided by disk arrays, it is possible to achieve performance that is almost as good as a non-parity-protected set of disks.

A Comparison of FFS Disk Allocation Policies: The 4.4BSD file system includes a new algorithm for allocating disk blocks to files. The goal of this algorithm is to improve file clustering, increasing the amount of sequential I/O when reading or writing files, thereby improving file system performance. In this paper we study the effectiveness of this algorithm at reducing file system fragmentation

Lessons from the Neighborhood Viewer: Building Innovative Collaborative Applications in Tcl and Tk: This paper discusses the development in Tk of a collaborative browser for scientific image databases. The browser, known as the ``neighborhood viewer,'' allows groups of neuroscientists to explore systematically a large collection of brain images.

Automatic Compiler-Inserted I/O Prefetching for Out-Of-Core Applications: In this paper, we propose and evaluate a fully-automatic technique which liberates the programmer from this task, provides high performance, and requires only minimal changes to current operating systems.

Using the Strategy Design Pattern to Compose Reliable Distributed Protocols: Reliable distributed systems involve many complex protocols. In this context, protocol composition is a central concept, because it allows to reuse robust protocol implementations. In this paper, we describe how the Strategy pattern has been recursively used to support protocol composition in the BAST framework. We also discuss design alternatives that have been applied in other existing frameworks.
