The first Tempo workshop will be held at IRISA (Rennes, France),
March 16-18, 1998. The aim of this workshop is to present a
three-day tutorial on Tempo, our partial evaluator for C programs,
and its applications to real size programs. A similar workshop
will be held at OGI (Portland, Oregon) at the beginning of april.

This workshop is the culmination of a three-year research project
at IRISA and in collaboration with OGI. Tempo has been used to
dramatically improve the performance of a wide range of commodity
operating systems components, including Sun's RPC, Unix signal
delivery, and the Berkeley packet filter. Tempo has also been
successfully applied to scientific programs, interpreters and
software engineering.

Specialization is an approach aimed at reconciling generality and
performance. It is based on a program transformation technique
called partial evaluation which consists in adapting programs with
respect to a known context. Exploiting the context allows a general
system to be instantiated for a particular environment. The
instantiated system is optimized in the sense that all the
operations that depended on the context have been performed.

During the workshop we will make available the first public release of
Tempo. Attendees will be given a full Tempo package. More information

A preliminary program of the workshop is listed below. More information
