Release 9.0-003 (August 2006) includes some bug fixes and a
couple of enhancements over and above the features in Release 9.0
(April 2005).
The enhancements in Release 9.0-003 are described below.
Header Arrays containing real numbers can be written in sparse form. When arrays are
very sparse (that is, contain a high percentage of zero values), this can reduce the size
of the Header Array file considerably.
As indicated in section 5.2.1 of GPD-5, compressions (that is, garbage collection)
are not done by default. We have found that, for some models, this leads to unnecessarily
large values of MMNZ etc. In some cases, the required values exceed the amount of memory
available. Accordingly, if compressions are not turned on via the Command file, we have
decided to let the programs turn on compressions in certain circumstances to try to avoid
this problem of unnecessarily large MMNZ values.
Complete details about Release 9.0-003 are documented in REL9003.PDF which you can
