Say I have slow and fast versions of some code, and want to report a speedup number comparing the two. I run the slow version $n$ times and the fast version $m$ times, producing times $(s_1, \ldots, ...
This question interests me for a while. At one extreme, I found papers, and some thesis that were outcome of change of a single parameter in a CFD code, like in the case of "Atmospheric boundary ...
I debated between asking this question here and in the Academia stack exchange, but decided Computational Science was the most capable of answering the question. I'm a new graduate student (~1 ...
Is there a published list of best practices to ensure longevity of code, with an eye towards reproducible scientific results? (e.g. open source, documentation practices, selecting dependencies, ...
I am producing 1d and 2d images using Matlab right now for comparison of accuracy against a given model. I need to compare my methods with the standard Gaussian .wfn model and I am going to do that by ...
I've seen a lot of publications in Computational Physics journals use different metrics for the performance of their code. Especially for GPGPU code, there seems to be a great variety of timing ...
The Journal of Computational Physics has been an important outlet for computational science in the past, and I have published there before. For the benefit of those (like me) who have signed the ...
(I hope this question fits this site; if not, accept my apologies). I ran a certain simulation, and got a time series y(t), t = 0, 1, ... 20. After trying some functions, I found that: ...
What material should I include with a journal article (or post online) in order to make my computational research reproducible?
Reproducibility has become more and more important in computational science research. (For instance, see this article by Roger Peng in Science; I'm aware of other such articles and web sites also.) ...
I asked this question on stackoverflow a few weeks ago, but have not gotten a useable answer, even after a colleague added a 150pt bounty. Is it possible to query the doi for each record in a table ...
What is a good, common way to express dictionaries (= maps) in pseudocode? I.e. datastructures that basically allow to store values for keys, iterate over all key/value pairs, test for inclusion of a ...
In light of the recent petition to boycott Elsevier, I was wondering what options we have in Computational Science for Journals which are completely open-access, Journals which allow/support ...
I have heard that some journals are rated more highly than others. Is this true? And if so, what are the criteria for judging the value of one peer reviewed journal over another? How do I find out ...
Reproducible research in computation aims to make the code needed to generate the results in a computational paper available to other researchers so that they can run this code to reproduce the ...
Scholarly papers in scientific computing (and many other fields, nowadays) typically involve some amount of code or even whole software packages that were written specifically for that paper or were ...
