Unix Distribution

The latest Jan 2, 1997 unix distribution, version 3, of the EGS4 code is distributed by the National Research Council of Canada (NRC). The URL for the NRC download site is http://www.irs.inms.nrc.ca/inms/irs/EGS4/get_egs4.html

Please contact Dave Rogers if you have problems downloading the unix distribution from the above site.

PC Distribution

The PC version of the EGS4 code was prepared from the standard unix distribution by Dr. Harry Eleveld. However unlike the current unix distribution, the latest (Oct. 21, 1997) PC distribution of the EGS4 code includes the PRESTA bug fix described by Iwan Kawrakow (Oct. 8, 1997), and it also includes Lahey compiled versions of the XYZDOS benchmark EGS4 application. The latest distribution of the EGS4 code for WinTel (PC) computers is available from (egs/codes/zip/egs4pc.zip).

NOTE: The PC version of the EGS4 code is distributed as a PKZIP file. Consequently, you will need zip utility such as the shareware program WinZip.
