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.
