Astronomical Image Processing System 31DEC20 Version

The 31DEC20 version of AIPS is now available as our obsolete version. It will not change even for serious errors, although it was patched in 2021. To install it, follow the advice below especially A Guide to the Install Wizard See the special Mac installation for information specific to installations on MacIntosh OS/X systems. Note that 31DEC20 is available both as a text installation (compilations done on your computer) or as a binary installation (compilations done by us). The former should work on all computers and requires much smaller downloads. But the latter can offer superior performance especially for Intel Macs and Linux. Given problems with compilers, the binary installation is likely to be the best choice unless you plan local development of AIPS code. Note that we have resolved many of the issues raised by modern gfortran compilers, so compiling your own version is not likely to be too difficult. The LNX64 and MACINT versions are compiled with a gfortran 6.3 version. Even the performance discrepancies have mostly disappeared. Note too that the Mac binary version is for 64-bit computers at Mac OS 10.10 or greater (the master Mac machine is now at 10.15).

Binary installation

1. Requirements:
   • Unix Workstation: MacIntosh OS X (Darwin) either PPC or Intel cpu, Linux/Intel, or Solaris/Sparc Ultra; 1 Gigabyte memory, 1 Gigabyte disk space (not counting your data). Binary installations which are now offered for MACPPX OS/X systems using NRAO's IBM xlf compilers for PPC-based systems or Intel's ifort for Intel-based systems, for SUL systems using SUN's SUNWspro compilers, and for LINUX systems using Intel's ifort compiler under RedHat.
   • Internet (ftp) access;
   • Perl version 5 (comes with most Linux systems);
   • The rsync utility is now used and the Secure Shell client and cvs utility are not required.
   • READING THE DOCUMENTATION!

2. Preliminaries for your installation:
   • For binary installations, get the Install Wizard file, but do not fetch the 31DEC20.tar.gz file. Remember the date/time (Greenwich) on which you started install.pl.
   • Read the On-Line Wizard Guide BEFORE PROCEEDING FURTHER! Also, use it as you proceed through the various screens presented by the wizard.
   • Place install.pl in the area that will be your $AIPS_ROOT (top-level AIPS directory).
   • If you have a previous installed version of AIPS:
   • Edit your $HOME/.AIPSRC file: change the CCOMOPT option to point at 31DEC20 and delete the DOWNLOADED and UNPACKED lines.
   • Use the same $AIPS_ROOT area for the new version
   • Just give a carriage-return (Enter) to the screens asking for information about hosts, disk areas, printers, tapes, tape hosts and TV services.
   • Make sure that the install.pl file is executable. Then, for binary installations,
     perl install.pl -n

3. Post-Install Steps:
   • Edit $AIPS_ROOT files AIPSPATH.SH and AIPSPATH.CSH to select which version of AIPS, if you have more than one, corresponds to NEW and OLD.
   • Upgrade the $SYSLOCAL/UPDCONFIG file to match any improvements you made in any previous version of that file. Make sure that the e-mail addresses in the file are correct.
   • Make sure you Read the Midnight Job instructions before enabling the midnight job on your system. You may run the MNJ via a cron, but most users elect to run the do_daily.hostname file by hand at times of their choosing.

Text installation

This form of AIPS installation is recommended only for sites that plan to develop their own software to run within the AIPS system or for sites with architectures other than those for which binary installations are available.

1. Requirements:
   • Unix Workstation: MacIntosh OS X (Darwin) PPC or Intel cpu, Linux/Intel, Linux/Alpha, Solaris/Sparc, Solaris/Intel, OSF1/Alpha, HP9000/HP-UX, SGI/Irix; 1 Gigabytes memory, 1 Gigabytes disk space (not counting your data), Intel 486/33 or better.
   • The text installation requires full developer-level support for X Windows, C, and Fortran. Systems using the GNU compilers may also need a separate installation of a non-default version of the Fortan and C compilers. Note that "full developer support" includes RPMs for X11 (e.g. XFree86-devel), ncurses (ncurses-devel), and cvs (cvs).
   • Perl version 5 (comes with most Linux systems);
   • Internet (ftp) access;
   • The cvs utility will now be used and the Secure Shell (ssh v1 or Openssh) client is not required.
   • READING THE DOCUMENTATION!

2. Preliminaries for your installation:
   • For a text installation, make sure that your computer has a C and a Fortran compiler plus a full set of XWindows include files and libraries. MacIntosh users may consult the special Mac installation instructions for information about these issues. Be sure to check which GNU compilers are known not to work with AIPS, including GNU versions 2.96, 3.0.3, 3.0.4, 3.3.x, and 4.1.x. Compiler versions (gfortran) 5.1, 5.3, and 6.4 are thought to work well.
   • For text installations, get the Install Wizard file.
   • For a text installation, get the 31DEC20.tar.gz file (over 177 Megabytes); this is re-generated on a nightly basis from our master code repository. Remember the date/time (US/Eastern) on which you started getting the file. Remember to use "binary" mode to copy the file.
   • For a text installation, get the Message Digest Checksum file (md5sum); compare this to the output of running "md5sum" on your copy of 31DEC20.tar.gz. Note that md5sum comes with Linux and is a standard GNU utility. If the output of "md5sum 31DEC20.tar.gz" does not match the file 31DEC20.tar.gz.md5sum or if there is no md5sum file, STOP! There's a problem; try a second copy (with binary this time) and if there is still a problem Contact us at our daip@nrao.edu address.
   • Read the On-Line Wizard Guide BEFORE PROCEEDING FURTHER! Also, use it as you proceed through the various screens presented by the wizard.
   • Place both the 31DEC20.tar.gz file and install.pl in the area that will be your $AIPS_ROOT (top-level AIPS directory).
   • If you have a previous installed version of AIPS:
   • Edit your $HOME/.AIPSRC file: change the CCOMOPT option to point at 31DEC20 and delete the DOWNLOADED and UNPACKED lines.
   • Use the same $AIPS_ROOT area for the new version
   • Just give a carriage-return (Enter) to the screens asking for information about hosts, disk areas, printers, tapes, tape hosts and TV services.
   • Make sure that the install.pl file is executable. Then, for text installations, run the script with the command
     perl install.pl
     

3. Post-Install Steps:
   • Edit $AIPS_ROOT files AIPSPATH.SH and AIPSPATH.CSH to select which version of AIPS, if you have more than one, corresponds to NEW and OLD.
   • Upgrade the $SYSLOCAL/UPDCONFIG file to match any improvements you made in any previous version of that file.
   • Make sure you Read the Midnight Job instructions before enabling the midnight job on your system. You may run the MNJ via a cron, but most users elect to run the do_daily.hostname file by hand at times of their choosing.

We do NOT plan to have a CDROM (actually DVD) with 31DEC20 on it after it is frozen. The DVD can be made but only if that is the only possible way for you to get AIPS.

If you have problems with our ftp server, please contact us.

You WILL want a Midnight Job!

If your site has a need for the current version of AIPS with updates via the Internet and the so-called midnight job, Read this information. It has additional information and instructions. Or Eric Greisen for further information.

Since releases of AIPS are planned to be only on an annual basis, the midnight job (now with easier setup and NO ssh) will be the only way for AIPS users outside of NRAO to avail themselves in a timely fashion of whatever enhancements, changes, or new functionality we add to Classic AIPS.

The MNJ is the only way in which you can fetch changes to your version of AIPS, other than a full re-installation. It works for both binary and text installations and is sometimes useful even for the "frozen" version of AIPS, since the most recent frozen version will be patched to correct egregious errors.

Distribution Statistics

Tools to monitor shipments of the tar balls and the binary releases as well as accesses of the cvs code maintenance system have been created and run since Spring 2003. We estimate "sites" by counting unique IP addresses. In each of the totals, an individual IP address is counted only once. In general, an IP address is used by only one user, but more than one IP address will be used by those users that use dial-up connections. Thus, these totals are a modest over-estimate. However, they are an underestimate of the number of computers used for AIPS since at many institutions a single IP address is used to provide AIPS to a number of computers. The table below shows the totals in various categories and has links to the plots of the cumulative totals. Note that the TST and NEW numbers for 2003 are for only part of the year as, of course, are all the 2020 numbers. These are indicated by the asterisk. The totals for TST and NEW include both binary and tar-ball downloads. The binary totals include binary downloads, but not binary MNJ accesses (which now use rsync).

The plots and numbers for 2020 are now final.
