SPARSE MATRIX DRAFT 10 (AND DRAFT 11 PREVIEW)
Brad Brim provided a Draft 10. In response to the consensus at the
January 27, 2010 meeting 'integer-label' was changed to 'sparse-label',
and a few rules no longer applicable to integers were deleted, and
a few rules were added for string-based labels. The changes were
discussed briefly and a few minor comments were made for clarity.
The string labels can have any ASCII text, but with these three rules:
(1) terminated with a ':' character, (2) not include the ':' character
anywhere else within the string, and (3) not start with a '(' character.
These rules are to make the distinctions between sparse-label and the
integer-pair syntax more distinct to avoid accepting ambiguous cases
due to simple typographical errors.
The changes were accepted, and Draft 10 serves as a new baseline.
Brad also had begun restructing in preparation for Draft 11. Bob Ross
showed a Draft 11 under preparation. Because this was not sent out,
it was only previewed to show what is being considered. The changes
provided a better organization for the rules and introduced a few other
terms such as "group" of index-pairs" to simplify the description of the
rules.
The officiale Draft 11 is attached to this e-mail and will be reviewed
at the next meeting.
BINARY DISCUSSION
Bob Ross mentioned that Walter Katz provided a Wikepedia link concerning
IEEE Standard for Floating-Point Arithmetic (IEEE 754) as a reference
for numerical data structures:
http://en.wikipedia.org/wiki/IEEE_754-2008
Bob had some clarication questions concerning the binary encoding.
Bob asked if there were any free utilities for binary conversions,
and Walter stated that he was not aware of any. Most software developers
can easily write code for the conversions with the stream IO functions.
Walter also commented that the tschk2 parser would be expected to
have a read/write mode for binary representation. Bob added that
it would be for both Touchstone 1.0 and 2.X versions. Walter
expected that the syntax and rules would be compatible with those
presented by Greg Edlund of IBM in earlier meetings. There was
no reason to try to be different.
NEXT MEETING
Draft 11 will be reviewd at the meeting next week. We will continue
discussing binary encoding plans, if time permits. Brad Brim indicated
that the Model Connection Protocol (MPC) proposal is not yet ready
for discussion.
