* New SAS/C 6.51 compiled version
Shortly before releasing the distribution, my new SAS/C 6.50 compiler (and
6.51 patch) arrived. This compiler has some exciting new optimization
options and includes many improvements of the existing optimizer.
For the first time in the history of PowerCache, the differences between
the 020/030/040 executables were signifficant enough to justify including
these versions in the distribution archive. Thus, you will find two new
executables named PowerCache.030 and PowerCache.040 resp. The installation
scripts have been modified to accomodate these two new versions.
If you have an A4000/030, or a 68030 accellerator board (such as the A530
unit for the A500), you should use the new 68030 version for maximum
efficiency. A4000 users and users with 68040 accellerators should go for
the 68040 version. For a complete list of all popular machines and their
CPU types, have a look at the "hardware requirements" section in the
manual.
All versions (68000-68040) were compiled with the new schedule optimizer
enabled, which gives 68040 users an extra boost regardless of which version
they use.
Because of the extra optimization, the benchmark section in the manual is
not completely up to date. If you did a test with the version in this
distribution, you would probably end up with better results than those
illustrated in the benchmark section.
* Installation scripts
The inclusion of the new 68030 and 68040 versions came at such a late stage
that it was impossible for me to obtain all the necessary new strings for
the installation scripts from the various translators. Some of the text in
the script is therefore still in english regardless of what language you
choose. I apologise for the inconvenience.
