Osterm iller) Subject: Supercomputers and Ada Message-ID: <17026@faraday.ptolemy-ri.arc.nasa.gov> List-Id: Ada On Super-Computers Workshop: Programming High Performance Computers. TRI-Ada T91 San Jose, CA October 21, 1991 Call For Contribution & Participation High Performance Computing solutions are becoming more wide spread because of inexpensive microprocessor technology and inno- vative computer architectures. These architectures rely extensively on parallelism in many formsQpipelining, vector processingQand in many degreesQ coarse to medium to fine grain. Ada with its numeric processing, tasking and generic abstraction features has the potential to address the growing problem of programming super- computers effectively. The aim of this workshop, which is held in conjunction with ACM SIG Ada sponsored TRI-Ada T91, is to bring together interested super- computer users, Ada technologistsQcompiler vendors, computer manufacturersQ and Ada 9X Mapping/Revision participants to ad- dress the following issues, each in a 1 and 1/2 hour session of panel and audience debate and discussion: 1) Users Needs Currently, FORTRAN is the lingua franca of super-computer users. What steps are needed to make Ada the language of choice for users of super-computers? 2) Compiler Technology Super-computer architectures require sophisticated compilers to achieve effective performance. Ada , for performance reasons, also requires a sophisticated compiler. How can both be accommodated? 3) Language Issues In some instances, the Ada Language Reference Manual restricts the use of parallel processing. Also, scientific users have specialized needs in handling floating pointing representation, storage and op- eration. What are the critical issues and what steps can be made to accommodate such issues now and in the Ada 9X revision process? 4) Wrap Up The results of the workshop Qlists of issues, proposed solutions and recommendationsQ will be summarized and published in Ada Letters. If you are doing work related to any of these areas and would like to bring your expertise and point of view to bear on the above ques-tions as a panelist, then we invite you to submit a short descriptionQ3 pagesQof what your interests are and in which session you are in- terested in participating. Short position statements from invited panelists will start each session and then the floor will be opened by a moderator for debate and discussion with the panel and the audi-ence. The dead-line for submitting a position brief as a speaker/panelist is October 15 1991. The audience attendance is limited to about 75 persons so please contact one of us as soon as possible if you are interested in attend- ing.
