We expect that KAI's kcc compiler will work fine on all platforms
supported by KAI. Above, I have only listed the platforms for
which we have tested kcc ourselves.

We encourage all OptSolve++ users to join the optsolve-users
email list and send all comments, questions, answers, etc. to To join this list, send a message

The rapid increases in the capabilities of computers and their
associated communication systems are opening up wonderful new
opportunities for information technology to serve humanity, from
health care to entertainment to complex product design to
disaster prediction. The focus of this conference is current and
future ways in which high-performance computing can be used in
the support of commercial applications. The power of "high-
performance" computing continues to increase with time. High-
performance computing systems may be based on multiprocessor
systems, clusters or farms of machines, parallel computers,
special-purpose architectures, computational grids, distributed
computing, etc. The set of computers that comprise the system may
be heterogeneous or homogeneous. For this conference, a single
processor general purpose standard machine is not considered a
high-performance system. Our working definition of "commercial
applications" in the context of this conference is loosely
defined as applications that are of interest to the general
public and can be profitable for a company to undertake, as
opposed to one-of-a-kind applications whose development would be
funded by a federal government agency for its purposes only.
Furthermore, to be appropriate for this conference, these
applications must require the use of a high-performance computing
system, typically because of the computational complexity of the
task, extremely large data sets that must be processed, the need
for a response in relevant time, or some combination of these.
he parent symposium concerns the convergence of information
technology and communication technologies. The topics we expect
to cover in this conference will involve this convergence in one
or more of the following ways: (1) the computers that comprise
the high-performance system will be interconnected by high-speed
communications; (2) the application being executed is gathering
its inputs remotely over a communications network; or (3) the
high-performance system executing the application is remotely
accessed by its users through a communications network. Possible
general topics for current and future applications of interest
include, but are not limited to:
- aircraft design
- airline industry reservation system
- airline scheduling problem
- automobile design
- bioinformatics and genomics
- business decision support
- chemical process optimization
- computational finance
- data mining and knowledge discovery
- data visualization and animation
- drug discovery
- e-business and e-commerce support
- entertainment
- geophysical exploration (including oil)
- global climate modeling and prediction
- ground and air traffic control
- image and speech understanding
- integrated circuit chip design
- mobility management for computing and communications
- molecular engineering
- multimedia support
- natural disaster forecasting and mitigation
- satellite imaging
- stock market modeling and prediction
- telemedicine and health care
- virtual reality
- web search engines

Technical questions about this conference may be sent to the
Conference Chair at

A special issue of "The Journal of Supercomputing" will be devoted to
this conference; authors of accepted papers will be asked if they want
their full papers reviewed for this issue.
