Compiler positions available for week ending December 26

This is a digest of ``help wanted'' and ``position available'' messages
received at comp.compilers during the preceding week. Messages must
advertise a position having something to do with compilers and must also
conform to the guidelines periodically posted in misc.jobs.offered.
Positions that remain open may be re-advertised once a month. To respond
to a job offer, send mail to the author of the message. To submit a
message, mail it to compilers@iecc.com.

Collaborative Research Project ICOS:
Intelligent COde Scheduling for Transport-Triggered Architectures


The objective of the ICOS project is to develop code generation techniques
capable of fully exploiting future instruction level parallel processing
systems. The research within the project centers around the usage of
annotations used in the compilation trajectory. These annotations assist the
compiler in such a way, that more and larger code motions are possible.


Key features of the ICOS project are:


o Use of language intelligence
    Annotations can be added to the program, either automatically, or by hand, by
    the programmer. In particular, ICOS will explore the automatic generation of
    annotations for programs written in a pure functional style, using
    intelligence about e.g. data types, which is available in functional
    programs. We expect that similar techniques can be used in other program
    domains, like the object oriented domain.


o Transport Triggered Architectures (TTAs)
    The compilation methods are targeted to a newly developed class of
    architectures, which is based on the principle of transport triggering. This
    architecture class includes the class of Very Large Instruction Word (VLIW)
    architectures, and is therefore able to exploit instruction level
    parallelism. In contrast to traditional VLIWs, transport triggered
    architectures are more flexible and scalable, use their hardware more
    efficiently, and can be designed for very short cycle times (that enables a
    large degree of superpipelining). Exploiting the extra capabilities of these
    architectures requires special compiler optimisations, which will be
    researched as part of ICOS.


o Flexible compiler framework
    The developed compiler framework will be flexible in two ways: Firstly,
    multiple languages (imperative, object oriented and functional) serve as
    input, and secondly a large range of transport triggered architectures (and
    VLIWs as subclass) serve as compilation target.


The ICOS project explores a new compilation philosophy, based on annotations
derived from either the programmer, or from builtin knowledge within specific
language domains. Based on these annotations, enhanced instruction scheduling
techniques will be developed which are able to exploit the extra freedom of
moving operations. This should reduce the currently increasing gap between the
amount of parallelism which hardware can offer and which current compilers can
exploit.


Requirements:
* A good degree in computer science
* Experience in one or more of the following areas: compiler construction,
    VLIW/superscalar code generation, functional languages, VLSI design
* An interest in both the practical implementation aspects as well as the
    theoretical background.
* The ability to work in a team.


One Ph.D. student will work in Delft on the backend of a C/C++ compiler for
TTAs and the other Ph.D. student will work in Amsterdam on the backend of a
compiler for a functional language to TTAs. The Ph.D. students are required to
work closely together.
