Update:
Based on the scattered arguments, discussions, and comments, the consensus seems to be to name this site:
"Computational Science" <-- header at the top
with a url of scicomp.stackexchange.com
Proposal: Scientific Computing (was Computational Science)
Since there seems to be some controversy over the recent change to the name of this proposal, I feel we should discuss the options and try to come to a consensus.
Firstly, it is obvious that some people believe that Computational science is too close to Computer science and that this may lead to confusion and inappropriate questions.
Other options proposed include Computational Natural Science, but this might give the impression that we aren't prepared to consider questions on computational methods in the social sciences. Computational Natural Sciences & Bioinformatics suffers the same problem of exclusion (the Bioinformatics is a subset of CNS as far as as I can see). Informatics was also suggested, but I think that for most lay people this term is just too obscure and it doesn't clearly describe the scope of the site.
Given the heavy use of HPC technology by the Scientific computing group where I work, I would support the inclusion of HPC in terms of questions, but since HPC is a means to an end, not and end in itself, I don't feel it needs to be part of the name. Finally, Computer Vision is now covered under the umbrella of Signal Processing Stack Exchange, which is already in beta.
I would suggest that the format for answers should be one name proposal per answer, along with reasoning for that proposal. It would help if duplicate proposals for the same name could be merged with the higher voted answer, either as comments or edits to the answer, and then the duplicate removed.
If people vote up all options they approve of, then we should get a better idea of how much relative support each option has and whether there are compromises to be made. Approval voting
Also, for each proposal, it would be good to suggest a suitable subdomain name. Scientific Computing would map nicely to scicomp.
... but the natural contraction of Computational Science would be compsci.
... which is usually used to refer to Computer Science.

when we've found our feet a little more, during the beta phase.scicomp
is a pretty good choice for sub-domain even if this community decides they prefer a different official name during beta.
