Call for Participation
Second ACM SIGPLAN Workshop on
Interpreters, Virtual Machines, and Emulators (IVME'04)
Washington, DC, Monday, June 7th, 2004
(in conjunction with PLDI'04)
http://www.ics.uci.edu/~franz/ivme/
featuring invited research presentations from
Sun Labs, Transmeta, and Microsoft
====================================================================
IVME'04 brings together researchers across the full spectrum from
(binary) translation to interpretation and emulation. We are happy to
announce that this year's conference will include invited presentations
from three of the key industrial research teams in this area:
* Bernd Mathiske from Sun Labs will talk about the relative design
trade-offs that affect Java Virtual Machines for hand-helds and other
resource-constrained devices.
* Dean Deaver of Transmeta will talk about the trade-offs between dynamic
translation vs. interpretation in Transmeta's Code Morphing software.
* Vance Morrison of Microsoft will talk about past, current, and future
performance issues in the .NET Runtime Virtual Machine.
Each of these speakers is a key design engineer in the respective project
he is presenting. These talks have been solicited expressly for IVME and
will feature highly technical presentations devoid of the usual marketing
fluff that are specifically directed at IVME's unique audience of
academics and practitioners in the field.
The six research papers presented at this year's conference were chosen
in a selective review process. We are extremely happy about the
groundbreaking ideas that the papers' authors will unveil to the world
for the first time during this year's IVME conference.
The detailed program is appended below. If you have any further questions
about IVME'04, please feel free to contact the General Chair at the email
given below. Please also pass this announcement to any colleagues who
might be interested.
I look forward to seeing you in Washington.
Sincerely,
Michael Franz - franz@uci.edu

Real-Life JVM Design for Mobile Devices
Bernd Mathiske, Sun Labs
The design of Java(TM) Virtual Machines for mobile devices is strongly
influenced by resource limitations (memory sizes, processor speed, power
consumption, etc.). For early designs like the KVM, the main challenge
was to meet the given restrictions at all. Meanwhile, the design space
has shifted and widened, accompanied by increasing user demands for
execution speed, interactive responsiveness and reliability.
Consequently, JVMs for mobile devices need to incorporate increasingly
sophisticated features, in some cases "trickling down" from larger JVMs.
It is not straight forward to adopt any of the latter, though, since
resource limitations simultaneously increase the urgency of enhancing
resource management and the urgency of simplicity.
In this tension field, we will review design decisions made for the CLDC
HotSpot(TM) Java Virtual Machine, a high performance product running on
mobile phones. Drawing comparisons with alternative designs in different
JVMs that support larger or smaller Java platform stacks, we will
determine practical viability and necessity boundaries for alternative
implementations of features (e.g. garbage collection,
multi-tasking),respectively for employing them at all (e.g.
preverification, interpretation, dynamic compilation). Related aspects of
testing, benchmarking and tuning will also be addressed.
Bio: Bernd Mathiske is a Senior Staff Engineer at Sun Microsystems
Laboratories working on Java(TM) Virtual Machine implementation. In
recent years, he led the productization of the CLDC HotSpot(TM) Virtual
Machine in Sun's Wireless Technology Group. He holds a PhD from the
University of Hamburg, Germany.
Experiences with Interpretation vs. Translation in Transmeta's Code
Morphing Software
Dean Deaver, Transmeta
Transmeta's Efficeon microprocessor is a full, system-level
implementation of the x86 architecture, comprising a native VLIW
microprocessor with a software layer, the Code Morphing Software (CMS),
that combines an interpreter, dynamic binary translator, ptimizer, and
run-time system. This software layer provides unique opportunities for
studying the tradeoffs between interpretation and dynamic translation
with various levels of optimization, while running arbitrary PC
workloads. This talk presents some results from such a study, and
provides insight into what mix of these emulation modes is most desirable
over the range of tested workloads.
Bio: Dean Deaver is a member of the technical staff at Transmeta, and is
currently responsible for various components of the Code Morphing
Software (CMS) Translator. Prior to joining Transmeta, he was an engineer
in the Alpha Migration Tools (AMT) group at Digital Equipment
Corporation, where he worked on binary translation for the Alpha and
development tools for the StrongARM architecture. Dean holds a MS in
Computer Science from Virginia Commonwealth University.
Performance Issues and Resolutions for the .NET Runtime Virtual Machine.
Vance Morrison, Microsoft
The .NET Runtime is an example of virtual machine technology "in action".
It forms the foundation of every C#, and VB application written today,
and is one of the most widely distributed pieces of virtual machine
technology. Performance considerations have been a driving force in its
design; however they may not be the ones you might have guessed.
Scalability, working set, and startup time turn out to be more important
considerations then the more traditional "instruction path" notion of
performance. In this talk I will provide a brief background on the
runtime, describe some of the performance problems we faced, and how we
solved them. Finally I will talk a bit about the performance challenges
we have still in front of us as ever more demanding customers use the
runtime.
Bio: Vance Morrison is the lead programmer for the 'just in time'
compiler for the .NET Runtime. He has been a member of the .NET Runtime
group since its inception over 5 years ago. He was a key designer of the
intermediate language used by the runtime, and participated in the design
of the much of the fundamental parts of the system (MetaData, IL, Object
Model, GC synchronization etc). He is associated with over 10 patents
associated with the runtime. He will undoubtedly be at it 5 years from
now, since we have only scratched the surface of what Virtual Machine
technology can do.
