Subject: RERO 0.0.25 - A software release manager
From: "Michael L. Brownlow" <mike@wsmake.org>
RERO 0.0.25 - Release Early, Release Often
RERO is a release automation tool. The goals of RERO are to provide a
framework for current release models and formally address release
management of software in both sophisticated and model-based development
environments for the purpose of increasing release throughput. The
perspectives of release automation, analysis, and process improvement
are some fundamental viewpoints that are held.

The Chrysler Group Adopts Innovative Technology
Approach To Impact Simulation Testing
Monday October 21, 9:05 am ET
* Use of a Linux Cluster of workstations results in new price-
performance curve for
part of the product development process.
* Collaboration with IBM, Intel(R), LSTC and Red Hat enables Chrysler
Group
to reach a new plateau in computer-aided engineering.
* Benefits include increased simulation speed and significant
reduction in hardware investment, while maintaining the same
precision per simulation.
DETROIT, Oct. 21 /PRNewswire-FirstCall/ -- The Chrysler Group unit of
DaimlerChrysler announced today
a revolutionary approach to the technology required to perform impact
simulations during vehicle
development. The announcement was made at the kickoff of Convergence
2002, the premier global
transportation electronics conference.
The approach utilizes a Linux cluster of commercial-grade PCs, also
known as workstations. It enables the
Chrysler Group to perform impact analysis simulation at a speed that is
20 percent faster than Company's
previously used hardware solution, maintaining the same precision
required from the analysis of the
simulations, and at a cost that is 40 percent lower than the other
solutions available on the market today.
"The dramatic shift we are seeing in the price-performance curve on
computers will allow us to perform
impact analysis with greater precision and reduced turn-around time,"
stated Bernard Robertson, Senior
Vice President of Engineering Technologies and Regulatory Affairs for
the Chrysler Group. "We expect to
see a direct contribution to the quality and safety measurements of our
vehicles, as well as improved
productivity, lower cost with faster speed-to-market."
Vehicle and occupant impact simulation accounts for 70 percent of the
simulation computing capacity that
the Chrysler Group engineering community utilizes on a daily basis. The
need for new and innovative
approaches that are implemented in a disciplined manner without
compromising design creativity is
significant.
The automotive industry is continually working to improve product
efficiency in the areas of variable cost,
cycle time and the function and performance of the vehicle. One means
by which great strides have been
made is in the area of computer-aided engineering (CAE) and simulation.
Supplier Collaboration Creates Innovative Approach
The new hardware strategy for simulation was born out of collaboration
between the Chrysler Group's
information technology team and IBM, Intel, Livermore Software
Technology Corp (LSTC) and Red Hat:
* The Chrysler Group's technical and engineering team helped
define the
needs for impact analysis, including hardware performance and
process
requirements. They also worked on system integration;
* IBM built the commercial-grade workstations, IBM Linux Cluster
and
Storage, to create a cluster. A108-node IBM IntelliStation
cluster was
deployed;
* Intel(R) Xeon(TM) processors running at 2.2 GHz and Intel(R)
PRO/1000 server adapters were used for high-level performance
and
flexible connectivity;
* LSTC provided a modified version of their LS-DYNA software to
perform
impact test simulations, in order to comply with Linux
standards; and
* Red Hat provided the Linux operating system, which is based upon
open
standards, in order for data to flow between differing computer
hardware, utilizing a common software (LS-DYNA).
IBM Global Services experts worked with the Chrysler Group's technical
and engineering team to
implement the solution. Integrated together were IBM Intellistation M
Pro 6850 workstations, TotalStorage
FAStT500 using Gigabit Ethernet servers and other components to create
a 108-node Linux cluster
system.
"The creation of this new automotive approach was a total team effort
between the Chrysler Group, IBM,
Intel, Red Hat and LSTC. Our Linux and High-Performance Computing
technical team worked closely with
LSTC and Intel to build, configure and benchmark the application at
IBM's Integration Lab in Minnesota,
before shipping the cluster to the Chrysler Group in Michigan," stated
Lucy Oakleaf, IBM Vice President,
Sales and Business Development -- DaimlerChrysler. "These skills and
this process helped eliminate
potential issues during the implementation of the cluster at the
Chrysler Group's Technology Center."
The cluster is based on Intel® Xeon(TM) processors running at 2.2 GHz.
Intel Xeon processors are the
heart of today's most advanced dual-processor (DP) workstations,
delivering exceptional floating-point
performance. The cluster also utilizes Intel PRO/1000 server adapters,
which provides fast, flexible
connectivity while enhancing performance with uncompromising speed,
security and scalability.
"The same great volume economics that Intel brought to the PC, we now
bring to workstations and servers,
delivering complete solutions for high-performance technical computing.
Intel-based clusters provide
outstanding performance at a fraction of the cost of proprietary
offerings," said Tom Gibbs, Director,
Industry Solutions, Intel. "This price-performance, coupled with
ongoing innovation by leading-edge
software vendors and automotive IT experts, allow engineers to create
better designs and quickly visualize
complex data."
Livermore Software Technology Corp of Livermore California is a
provider of finite element simulation
software for the worldwide engineering and academic community. LS-DYNA
is widely used by the
automotive industry to analyze vehicle designs. LS-DYNA accurately
predicts a car's behavior in a collision
and the effects of the collision upon the car's occupants. With
LS-DYNA, automotive companies and their
suppliers can test car designs without having to tool or experimentally
test a prototype, thus saving time
and expense.
An Evolution in Impact Simulation Testing
Since the early 1980s, the Chrysler Group's impact simulation strategy
began with the adoption of one
super computer that was used to run tests in a virtual world,
replicating real-world scenarios. The cost of
those computers at the time was tens of millions of dollars.
Technology evolved in a way that enabled the Chrysler Group to move
from the one large computer to a
network or cluster of computers for more efficient simulation
computing, at a faster rate and lower cost.
This phase, taking place between 1996 and 1999, introduced the
Unix-based machines within the network.
Today's announcement marks another shift in the use of innovative and
emerging technology. The Chrysler
Group is able to utilize workstations in a network and marry the
LS-DYNA software that has become an
auto industry standard via the use of a Linux operating system.
The Move to Linux for Impact Analysis
Linux is an open-source operating system, the brain of the computer. It
runs on a wide variety of hardware
platforms, from small desktop systems to large mainframes or
supercomputers.
Linux is cost-effective, reliable, and scalable that enables users the
flexibility of running one operating
system on a variety of hardware, often from different vendors.
The Chrysler Group will continue to look at new ways of applying the
Linux Cluster technology to its other
types of simulations, such as computational fluid dynamics, noise
vibration and harness, metal forming,
among others.
