Re: [Npsource-cbpmodel] Have you run the CBPModel with Ubuntu?

[Paine, J. <joh...@ae...>]

Cherie:

I compiled and ran the Phase 5.2 and 5.3 Watershed Models using both Ubuntu and Fedora on different desktop PCs. One had 6 GB of RAM and worked fine. Ultimately I stuck with Ubuntu. That was in 2010 and 2011, and my memory is rusty. I still have it compiled on an Ubuntu computer in my office but haven’t updated it in quite some time.

I compared modeling results with what Bill Keeling and others at DCR/DEQ got on their computers in 2010 and 2011. There were some significant differences in the computational results based on which computer was used—which I attributed largely to differences in the Fortran compiler being used (although I didn’t bird dog the exact cause because of the investment in compilers and the time that would have been required). The problem could also have been related to the large number of data files being written and read. (I would recommend an SSD drive to speed up the runs.) Attached is a self-explanatory email I generated that summarizes Phase 5.3 model comparisons between Ubuntu 10.04 and Fedora 13.

I wrote a Phase 5.2 installation guide (attached) for Fedora—it is out of date now but might be helpful. Phase 5.3 was a lot easier to install and compile.

Also attached is a run guide that came from Gary Shenk or Mike Barnes (I think) at EPA/CBP.

Good luck.

Subject: [Npsource-cbpmodel] Have you run the CBPModel with Ubuntu?

We are wondering if anyone has successfully run the CBP model with Ubuntu? At one point someone here tried for a day or two to set the model up on a machine with Ubuntu and ran into problems and switched to Fedora. But we are buying a new machine and are considering trying Ubuntu again. Any experience or insights would be greatly appreciated.
