Title: COCV 2002: International Workshop on "Compiler Optimization Meets Compiler Verification (COCV 2002)" Deadline: 3 Dec 2001 Conference: 13 April 2001 Web page: http://sunshine.cs.uni-dortmund.de/~knoop/cocv02.html Synopsis: Semantics preservation between source and target program is the commonly accepted minimum requirement to be ensured by compilers. The precise meaning, however, is often only implicit. As a rule of thumb, verification tends to interpret semantics preservation in a very tight sense, not only but also to simplify the verification task. Optimization generally prefers a more liberal view in order to enable more powerful transformations otherwise excluded. Calls for Participation: Title: The Second IEEE Workshop on Internet Applications (WIAPP `01) Conference: 23-24 July 2001 Location: San Jose, California, USA Web page: http://www.cs.berkeley.edu/~gribble/wiapp01/ Synopsis: The goal of this workshop is to bring together leading application and network designers from academia and industry to exchange ideas about the problems they are facing and the functions they are expecting each other to provide. Networks and applications have a symbiotic relationship, each vastly affecting the other. On one hand, applications must take into account network performance, transport protocol design, and higher-level protocol design to achieve acceptable performance and robustness. On the other hand, emerging network technologies are being determined in part by the kinds of applications that we wish to run on them. Title: HOT Chips 13 -- A Symposium on High-Performance Chips Conference: 19-21 August 2001 Location: Stanford University, Palo Alto, California Web Page: http://www.hotchips.org Synopsis: Hot Chips 13 brings together designers and architects of high-performance chips, software, and systems. Presentations focus on up-to-the-minute real developments. This symposium is the primary forum for engineers and researchers to highlight their leading-edge designs.

Special announcement: In Memoriam Jochen Liedtke --------------------------------------------------- From: Hermann Härtig Sent: Monday, June 11, 2001 4:08 PM Subject: In Memoriam Jochen Liedtke It is with sorrow that we announce the death of Jochen Liedtke. He died unexpectedly on Sunday June 10th. Jochen Liedtke, in memoriam. Jochen studied mathematics at the University of Bielefeld, completing his diploma in 1977. The focus of his thesis was the novel programming language ELAN. Jochen's first operating system was a by-product; a run time environment for ELAN was needed on small Z80 micro computers. The result of Jochen's effort, EUMEL, was based on two simple principles: persistent processes and data spaces. All data of the entire system including process control blocks and data space descriptors were contained in these data spaces. They could be copied efficiently and atomically using copy on write and garbage collection techniques. By copying the "data space of data spaces" every few minutes, a complete copy of the entire system state was taken and lazily written out to disk. Thus, process persistence came for free (at least conceptually). Sending around data spaces in synchronous messages was the only means of process interaction which made it easy to build a simple distributed EUMEL system. The paging device was a floppy disk (what else on a cheap computer at that time). In 1984 Jochen moved to GMD, the German National Research Center to build a "native code" version of EUMEL, called L3. This was the time when microkernel based systems were en vogue. Soon however, many researchers gave up their attempts to build the really fast message passing systems that were needed to run device drivers and other performance critical components at user level. Declaring "The Increasing Irrelevance of IPC Performance for Microkernel-Based Operating Systems", IPC was avoided by co-locating drivers and other components back into the kernel. Jochen however accelerated IPC by factor of 20 over comparable systems. The methods, most based on a thorough understanding of the interaction of modern microprocessor architectures with operating systems, were published in his SOSP 1993 publication ("Improving IPC by Kernel Design"). Still, L3 was not widely used (except in about 3000 installations in German law practices) because of its very special user and programming interface. Consequently, Jochen started close cooperation with Dresden University's operating systems group to build a Unix-like interface on top of L3. During this time, he invented hierarchical external pagers, another important feature that allowed physical memory management to be done in user-level pagers (SOSP 1995, "On Micro-Kernel Construction"). Jochen completed his PhD on guarded page tables in 1996 at TU Berlin. He demonstrated that not only was he a successful operating systems builder, but he also excelled with contributions to computer architecture. Jochen began working at IBM's T.J. Watson Research Center, NY in 1996. The result was L4, a 12KB extremely fast "second generation" microkernel. During many visits to Dresden's operating systems group, he helped to build L4Linux, a user-level implementation of the Linux kernel that demonstrated the effectiveness of Jochen's approach (SOSP 97, "The Performance of microkernel-based Systems"). His work gave research on microkernel systems fresh impetus and gained him international acknowledgement. Since 1999, he became professor for operating systems at the University of Karlsruhe. He was an inspirational professor, adept at keeping students deeply interested in his subjects. This was reflected by the high popularity of his lectures among students. Jochen also continued working on SawMill Linux, a multi-server version of Linux, and other related micro-kernel subjects. Several operating system research groups in Europe, Australia and the US either base their work on Jochen's or draw from his results. He was highly acknowledged for his scientific achievements which are reflected in numerous honourable appointments to program committees. Those who knew him remember the energy, stamina, and astute analysis with which he not only tackled his own scientific issues but also supported staff and colleagues. Not only expertise, but also friendship and mutual understanding played an important role between him and those he worked with. This cooperation developed numerous friendships over many years and large distances. Many colleagues, staff and students enjoyed his generous hospitality, exceptional culinary skills, and taste for good wine. Jochen is survived by his wife Adelheid with whom he lived together in harmony. Her constant support was instrumental in his many achievements.
