The number of bug fixes and changes in
31DEC00has become so great that we can no longer make the older
15OCT99version available. Please get the newer version instead, and also refer to the Midnight Job page for how to keep your copy of
31DEC00fresh and current.
15OCT99 AIPS is no longer available, you can
still read the associated AIPSLetter
(PS, 804 Kbytes; also available gzipped, 337 Kbytes).

As with the previous release, the
IBM architectures were not tested for this release; binaries
for them were not generated and active support within AIPS for these
architectures has stopped.
Since 15APR98, AIPS has used the EGCS version of the GNU compilers with
great success, mainly as it gives a considerable performance boost over
the older gcc/f2c package. We now require use
of the EGCS compilers (or the new merged version 2.95 or later) for
compiling AIPS with
g77. Version 1.1.2 is
used in-house; we have not yet tested the 2.95 version of gcc/g77 at this
time, though we do not expect any surprises (and initial results from the
field indicate it's fine). AIPS assumes the
glibc based C library.
You do not want to compile AIPS with the old f2c/gcc
combination, so the
f77 script formerly used in the
$SYSLINUX area has been removed.
The use of the GNU g77 compiler gives a factor of 2 improvement over the performance of the now obsolete f2c/gcc combination. Several outside users have opted for the combination, given the AIPSMarks of about 6.7 on a pentium pro 200, 9.6 on a Pentium II 300, up to 16.1 on a Pentium II 450 (dual processor, 10,000 RPM SCSI disk), and 21.5 on a Pentium III Xeon 550 MHz (with lots of memory and very fast SCSI disks). See the DDT Benchmark page for more details.
If your site has a need for the current version(s) of AIPS with updates via the Internet and the so-called midnight job, Read this information. It has step-by-step instructions. Or contact Pat Murphy or Eric Greisen for further information.
As there are no further releases of AIPS planned beyond
15OCT99, the midnight job (now with easier setup) will be the
only way for AIPS users outside of NRAO to avail of whatever
enhancements, changes, or new functionality we add to Classic AIPS in the
15OCT99 CLASSIC AIPS Distribution to be inserted here soon...
