    1 Introduction

    User Customization of Virtual Network Interfaces with U-Net/SLE David Opp enheimer and Matt Welsh fdavidopp,[email protected] Decemb er 9, 1997 Abstract We describ e U-Net/SLE Safe Language Extensions, a user-level network interface architecture which enables p er-application customization of communication semantics through downloading of user extension applets, imple- mented as Java class les, into the network interface. This architecture p ermits application s to safely sp ecify co de to b e executed within the NI on message transmission and reception. By leveraging the existing U-Net mo del, applications may implement proto col co de at the user level, within the NI, or using some combination of the two. Our current implementation, using the Myricom Myrinet interface and a small Java Virtual Machine subset, obtains go o d p erformance, allowing host communication overhead to b e reduced and improving the overlap of communication and computation during proto col pro cessing. 1 Intro duction Recentwork in high-sp eed interconnects for distributed and parallel computing architectures, particularly workstation clusters, has fo cused on developmentofnetwork interfaces enabling low-latency and high-bandwidth communication. Often, these systems bypass the op erating system kernel to achieve high p erformance; however the features and functionality provided by these di erent systems vary widely. Several systems, such as U-Net [26] and Active Messages [27], virtualize the network interface to provide multiple applications on the same host with direct, protected network access. Other systems, including Fast Messages [16] and BIP [17], eschew sharing the network in lieu of design simplicity and high p erformance.

    The Personaljava Platform: a Revolution

    SUN MICROSYSTEMS BROCHURE PERSONALJAVA™ The PersonalJava™ Platform A REVOLUTION PERSONALJAVA™ TECHNOLOGY FOR CONSUMER DEVICES Since PersonalJava™ technology was introduced, it has enjoyed widespread support and momentum in the consumer electronics industry. PersonalJava technology is a revolutionary software environment designed to bring the power of Java™ technology to personal, consumer, and mobile devices. Based on Sun’s acclaimed Java application environment, PersonalJava technology is ushering in a new era of network-connectable devices that can communicate with a wide range of information sources on the World Wide Web or other network. Already, devices such as web phones, digital set-top boxes, personal digital assistants (PDA’s) and car navigation systems are rolling out with this exciting technology. With the PersonalJava platform, new content and functionality An address book application using the baseline Touchable can be delivered to the device after it is in the hands of look-and-feel design. the end-user, thereby enriching the device’s usefulness and product life. Broad Adoption From its inception, PersonalJava technology was designed to shift the burden of innovation in consumer electronics from hardware to software where the development cycles Applications and Applets are faster, the business model is more leveraged, and the pace of innovation is accelerated. Everything you need for Optional Libraries innovation is already in place, including a broad industry knowledge base about Java software, and the infrastructure to support it. All of this can help you to lower your reliance on proprietary systems and their accompanying support PersonalJava costs. Since writing to the PersonalJava API means using Core Required Libraries Platform the popular Java programming language, the standard Java™ Development Kit (JDK™) toolkit or familiar off-the- shelf development tools can be used.
