--Computer Performance Evaluation
--Scientific Programming Languages
--Programming Environments
--Distributed Computing
--Massively Parallel Processing

Contributed presentations in lecture and poster form are invited in all areas
consistent with the conference themes. A description of your presentation
must be submitted on a SIAM abstract form, which can be obtained by contacting
SIAM. A contributed presentation will be considered for one of the following
categories: a 30-minute lecture, a 20-minute lecture, or a poster format.
When submitting your abstract, please indicate the type of presentation for
which you would like to be considered. A limited number of papers will be
selected for 30-minute talks, but all others will be considered for 20-minute
lectures or poster formats. The poster sessions will be organized by themes
to enhance interaction between presenters and attendees.

If you wish to be considered for a 30-minute presentation, we ask that, in
addition to the 100 word abstract submitted on a SIAM abstract form, you
should also submit a 750 word abstract typed on plain white bond paper. This
750 word extended abstract will be used in selecting the 30-minute
presentations. The selection of presentations will be made in the first week
of December 1990.
