2001 CERNLIB Release
Version 2001 of the CERN Program Library for the CERN
supported platforms and compilers
was released on
Monday, 11 June 2001.
To fix the bug in PAW for some uses of the "opera/add" function
an update was made on
Monday, 18 June 2001.
The basic code was frozen on
7 May 2001.
Major changes
-
Lapack has been separated from mathlib and requires
liblapack3.a and libblas.a,
mainly to avoid name clashes with kernlib and naglib, but also to give users
more flexibility in managing these libraries. For example, users only
referencing Lapack should change from "cernlib mathlib" to "cernlib lapack".
-
Pawlib also references Lapack so users of pawlib applications may need to
change their link sequence, the most likely being interactive
geant321 and
geant++ applications. However, the "cernlib" command has been
changed to help with backwards compatibility.
-
Monte Carlo libraries:
-
There are new versions of the Monte Carlo libraries
pdflib804, isajet751 and pythia6152.
As usual the previous versions can be obtained from the
obsolete/lib directory for the relevant platform. Note that the previous
pdflib had no version number.
-
Pythia had dummy routines (pdfset, structm and structp) which prevent easy use
of pdflib804 on most Unices. These have been removed and made available in the
new library libpythiad.a for those users who cannot use the recommended link
sequence
`cernlib pythia6152 pdflib804`.
-
Jetset74 had dummy routines (pdfset and structm) which prevent easy use of
pdflib804 on most Unices. These have been removed and made available in the new
library libjetsetd.a for those users who cannot use the recommended link
sequence
`cernlib jetset74 pdflib804`.
-
Notes on Monte Carlo releases:
-
Some years ago, when the new version of Pythia was released, it was
firmly pointed out by the Monte Carlo authors and physicists from
Opal and Aleph that the old Cernlib policy on these libraries was
inherently dangerous and that users should be made aware by the version
number which version (and Physics) they were getting. This has been
applied to Jetset, Pythia, Isajet, Photos and now pdflib, and the user
friendly but dangerous links were broken.
-
So our policy is to find a compromise between the latest stable version
from the authors and what is required by the CERN experiments. The
previous versions are made available by keeping them in the
"obsolete/lib" directory for the relevant platform.
-
In the case of pdflib, the author requested that pdflib804 should
replace the very old pdflib which was created before the new policy was
introduced. So, users are strongly recommended to change to
pdflib804. If, for some reason, they can not do so, then
version 7 can still be used from the old or
obsolete directories.
