I wanted to report the latest status of my efforts; I got pulled onto a high-priority project at work and haven't had time to get back to Atlas until this week. Here's the story: 1. GCC 3.0 was released on 18 June 2001. It is installed and appears to be functioning correctly on my 1.333 GHz Athlon Thunderbird. The rest of my software is stock Red Hat Linux 7.1. 2. I downloaded the Atlas 3.3.1 developer snapshot and built it using GCC 3.0 on the aforementioned Athlon, selecting the "3DNow2" option and letting it grind overnight through all of its tests. The "SUMMARY.LOG" file is attached; I have all the other files if anyone is interested. It takes about eight hours at 1.333 GHz, BTW. 3. R-1.3.0 was released last week. This is the first version of R that makes extensive use of Atlas if it is available. R-1.3.0 builds and passes all its built-in checks using GCC 3.0 and the Atlas 3.3.1 compiled with GCC 3.0. I haven't put much time into this particular build of R yet, but I have been using R-1.3.0 on Windows for the high-priority work project. One of the main contributors to R, Prof. Brian Ripley, has repeated at least the GCC 3.0 testing and has blessed it for R compilation. The one project I haven't tried that I want to attempt at some point is integrating R with Atlas on a Windows system. To my knowledge, no one is doing this; R is a volunteer project and apparently nobody has volunteered yet. If GCC 3.0 has filtered to Cygwin or MinGW32, I may take a shot at it, but I'm not really interested until that happens. -- M.
