You could ship that known environment as an optional download.

This is great! The ending phase really gives you the same feeling of “screw everything else, I need to finish this paper” rushing to get the final stuff out.

That is incorrect for scientific data. The limitations are: a) Massive data volumes (~100 Gb - 1 Pb/project) ai) This means that data is typically stored on limited access machines like HPC clusters bi) This also means that ship

No it’s not, this even goes to things like reference letters. US letters for the same candidate are always much stronger and use very different language.

Because MAME is effectively an emulator for arcade games and dolphin is a state-of-the-art console emulator? It is generally not be possible to get the level of fidelity and performance of a custom emulator out of a general-purpose framewor

For part a) that is only true for a small selection of observations. A huge proportion of astronomical science comes out of surveys that typically use large fields of view. Additionally, observation times can be very long, so even if you ar

That’s just not true, most of Eastern Europe sees extreme temperature variation similar to New England.

Implementing O(N ln N) or O(N) gravity on GPUs (which I guess is what is underpinning this) is both much more difficult and it's unclear whether it would actually run faster for any reasonable number of particles. Don't forget abo

I worked a while ago on something similar, using a state-of-the-art universe simulation model (including hydrodynamics too). The simulations don't run in real time, but people may be interested as we provide a bunch of information as y

In TFA they state that the weight loss was an incidental part of the experiment and in fact they thought they would gain weight.

$n00k of compute time is nothing, sorry. This is the kind of thing that academic institutions can give out for free…

Ah, we use the ML methods to understand what happens to a large collection of galaxies (maybe 100k - 1 million), all co-evolving together. Trying to use these methods v.s. direct simulation on individual galaxies is a no-go, too many nonlin

Similar things are happening in galaxy formation too; numerical models here cost tens of thousands - tens of millions of cpu hours to run, and have maybe 8-10 free parameters. We use emulators based upon a training set of maybe 100-200 real

This depends on the region/university/timescale/etc. Consider this: student at institution A (UK) writes code, postdoc at institution B (USA) modifies it, shared with researcher at institution C (China) who runs it for a pape

From my perspective (postdoc in astrophysics) things are quite complicated. I agree generally with data and code sharing policies (all of my recent papers include zenodo deposits of data, and I work on a large open source simulation code).

Yes, basically a bunch of huge telescopes across the planet have their images combined to give an effective mirror size of the entire earth, so one satellite is not going to cut it (even including the fact that IR has a shorter wavelength).

Sorry I'm a bit late to this, but those simulations take 10s - 100s of millions of Cpu hours (i.e. costs of millions - 10s of millions of dollars), so that's not practical.

It doesn’t really work like that. For instance, imagine you have a simulation with billions of particles in it. To construct reduced data you may need to use many fields (position, temperature, composition) of all particles over many output

Well these are scientific articles and as such must be preserved, the cost of which must be paid for sooner rather than later. So it's not just the 'wire cost' of sending PDFs around, but the archival work too that needs to b
