Astronomical Image Processing System 31DEC07 Version

The 31DEC07 version of AIPS is available as our "frozen" version. To install it, follow the advice below especially the new A Guide to the Install Wizard See the special Mac installation instructions for information on the steps which need to be taken to allow AIPS to be installed on MaxIntosh OS/X systems. Note that 31DEC07 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 Macs, Intel Linux and Solaris. Given recent problems with compilers, the binary installation is likely to be the best choice unless you plan local development of AIPS code.

Quick Start

1. Requirements:
   • Unix Workstation: MacIntosh OS X (Darwin), Linux/Intel, Linux/Alpha, Solaris/Sparc, Solaris/Intel, OSF1/Alpha, HP9000/HP-UX, SGI/Irix; 512 or more Megabytes memory, 500 Megabytes disk space (not counting your data), Intel 486/33 or better.
   • The normal 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). The binary installation frequently does not require most of these things, but rsync and cvs are required
   • 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:
   • The compilers, X Windows developers tools, etc. are not required for binary installations which are now offered for MACPPX OS/X systems using NRAO's IBM xlf compilers 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 9.
   • 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, and 3.3.x. Compiler versions 2.95.3, 3.2.2, 3.4.3, and 3.4.4 are thought to work adequately.
   • For text and binary installations, get the Install Wizard file.
   • For a text installation, get the 31DEC07.tar.gz file (over 91 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 31DEC07.tar.gz. Note that md5sum comes with Linux and is a standard GNU utility. If the output of "md5sum 31DEC07.tar.gz" does not match the file 31DEC07.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.

3. You have or do not have a previous installation of AIPS:
   • Download the Install Wizard;
   • 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 31DEC07.tar.gz file (if doing a text installation) 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 31DEC07 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
     or, for binary installations,
     perl install.pl -n

4. 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.

We plan to have a CDROM with 31DEC07 on it --- but only around January 2007 after it is frozen. You could wait if you are silly, but a source code or binary installation and the MNJ would be preferable.

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.

WHATSNEW in 31DEC07 AIPS

All "array processor" code has been changed to use dynamic memory rather than a fixed pre-compiled memory allocation. Large problems will request large amounts of memory but many will run in smaller memory if they have to. Small problems will not demand the large memories previously required to support the largest problems.

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 2007 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 and binary MNJ accesses.

The plot for 2007 has stopped changing and the numbers are complete.
