13 GOSIA 2007 RELEASE NOTESThese notes include updates as of May 29, 2008.The original GOSIA code was developed in 1980 by T. Czosnyka, D. Cline and C.Y. Wu at the Universityof Rochester. In the years since, several other versions of the code have been developed: GOSIA2 and PAWELby T. Czosnyka, and ANNL by R. Ibbotson. These Release Notes are for the 2007 version of GOSIA. GOSIA2is being upgraded in parallel with GOSIA and thus most of these release notes also apply to GOSIA2. Theserelease notes do not necessarily apply to PAWEL or ANNL.The coding of the GOSIA suite of codes was maintained by Tomasz Czosnyka from 1980 until 2006.Since 2007 Nigel Warr has upgraded the coding of GOSIA and GOSIA2. He has repaired several bugs,and made significant improvements in structure, standards, and compatibility to both GOSIA and GOSIA2.The management and future development of the GOSIA suite of codes now is done by the Gosia SteeringCommittee, which comprises Douglas Cline, Adam Hayes, Pawel Napiorkowski, and Nigel WarrValuable contributions to GOSIA were made by the following people.L.

Soc. 28, 745 (1983).University of Rochester internal laboratory report UR/NSRL 308/1986Some concepts used come from the 1978 Winther, de Boer code COULEX and from the deexcitationcode CEGRY developed by Cline and coworkers at Rochester. However, the parts taken from both codesare in most cases completely rewritten, so the similarity of variable and routine names may be misleading.ResourcesGOSIA is now being maintained at the University of Rochester. It is recommended that users checkthe GOSIA website at Rochester periodically for important updates to the code and the manual, as well assample input and output files and other information. Chapter 11 of this manual provides novice users withinstructions, tutorials, etc.http://www.pas.rochester.edu/~cline/Research/GOSIA.htmCompiling GOSIAGOSIA 2007 compiles on most 64-bit systems with GNU g77, using the default compiler settings.Chronology of Major Changes(July 2007, N. Warr) - Major update of the coding of GOSIA was made that incorporated thefollowing changes:1) Explicit 64-bit Precision Upgrade:Previous versions of the GOSIA code did not explicitly specify 64-bit precision; the user was expected tocompile the code at the highest machine precision available. The current availability of 64-bit machines andthe accuracy problems which arise when relying on 32-bit precision have led to the decision to make the 2007version fully and explicitly 64-bit. Modifying the code to run with 32-bit precision is discouraged. Earlierversions of GOSIA had some portability problems arising from misalignment of common blocks. In GOSIA2007 the common blocks have been re-ordered so that the 64-bit real variables come before the 32-bit integervariables, in order to eliminate alignment problems.2) Structure and standards:195
