Re: [femm] high performance computing options for FEM

[Gregory Quinting <gregq@xxxxxxx>]

Mr. Starcevich:

*nix is a serious option (any good excuse to get away from Win) ... My impression
from reading MS white papers is that they support enterprise server database
and web applications, but not so much for number crunching, perhaps because
of the latter being seen as a specialized and not very lucrative market,
(pharmaceuticals and biotech -- molecular modelling, etc.  notwithstanding). 

Thanks for your comments.
