As you can see from the new International Resources page on the website, there is a lot of interest around the world in FDS and Smokeview. I am happy to see that people are willing to help each other make FDS and Smokeview more accessible to others.
But, just how much international interest is there you ask...?
Well, I have been using Google Analytics to track website activity and have just posted a nice PDF summary of the visitors from 77+ Countries visiting the website. The report covers the time from April 26th, 2007 (when I enabled the tracking), until yesterday July 2rd, 2007.
Here is the link to the PDF report: http://www.fds-smv.net/VisitorsByCountry.pdf
It is interesting to see where visitors are coming from, how long they stay, what pages they are spending the most time on, etc. I will be using some of this information to further enhance the quality and quantity of information on the site.
As a side note, you will notice a fairly high bounce rate. This is basically when someone leaves the site from the same page they started on. On the FDS-SMV website. this is by design. We are trying to make pages that are on topic and complete so that a visitor can get to any information they need on the page they visit (typically the homepage) and can move on from the site in less than 2 clicks. My goal is to have a visitor come to the site, find what they need quickly and then go get some real work done. From these initial statistics, it seems that my plan might be working.
Finally, I want to take a second to recognize all our our international visitors, and thank you for being a part of the FDS-SMV community, your presence and support is welcome.

New International Resources Page on FDS_SMV Website.
A few weeks ago, I made a call out to the FDS-SMV user community for translators and the response has been impressive and very much appreciated.
There is now a new page on the FDS-SMV website with links to email addresses and websites/documents that these generous people have provided. There is a link under User Support on the Homepage and here is the direct link.
See: http://www.fds-smv.net/internationalresources
If you would like your name added to the page, to assist with helping users in a language you are fluent in, please email me your name, email address and if you have any documents or web sites specific to FDS-SMV in that language, include them as well.
Thank you again to all of you who generously offered your time and support.

PPC XLF compiler now working for OS X 10.4!
Well, I finally got it to work!!! In hindsight, is was not hard at all. Basically a small change in the xlf.cfg file and an updated environment variable. Not as difficult as some websites would like you to believe. :)
The good news is that there are some nice improvements in performance on the G5 platform.
But, as you can see, my Intel MacBook Pro laptop is significantly faster than both the Absoft and IBM compiled versions of FDS5_RC6 on the Dual G5.
I ran the room_fire.fds Verification case long enough to develop a trend then stopped it.
I don't expect different results if I run the case to completion.

So far it looks like the XLF compiled version of RC6 is almost twice as fast as the Absoft version. But, the Intel compiler on the Intel Mac spanks them both with twice the speed of the XLF version and almost four times the speed of the Absoft version.
At least this confirms that I need to switch to XLF for G5 builds and it also means that Glenn should be able to build G4/G5 versions of Smokeview again. :)
