why the hell has no one ported numpy/scipy cobol libraries i mean i know the practical answer to this question, but no one got a wild one up their rear end to at least make a go of it?

cobol programmers get paid too well doing cobol to bother doing python for free. i am also not quite sure why you want it.

is fortran still faster than c for some types of numeric calculations for deeply technical yet tedious reasons?

redleader posted:is fortran still faster than c for some types of numeric calculations for deeply technical yet tedious reasons? That's not changing any time soon. tl;dr is that Fortran doesn't allow programmers to do arbitrary things with memory and that means the compiler can make more assumptions about how code behaves and that makes optimization easier.

if you're serious about high-performance numerics you should be writing CUDA anyway oh also, check this out: https://tvm.apache.org/2018/10/09/ml-in-tees a custom compiler for running ML models inside SGX enclaves. now the system that implacably denies your loan application could be running inside your very own computer! And you *still* won't be able to see how it works! animist fucked around with this message at 03:33 on Dec 5, 2019 |

CUDA's great if what you're trying to do exhibits SIMD parallelism. If not, it's a non-starter.

redleader posted:is fortran still faster than c for some types of numeric calculations for deeply technical yet tedious reasons? this is a weird comparison since fortran is in many ways a much more alive language than c, having been modernized to add e.g. proper modules, operator overloading (pretty big deal for numerics), forall loops, and if you dip a far in as fortran'03, object orientation. also, yeah, cuda is another super-important leg to all this stuff, but tons of kernels are extremely hard to parallelize and require a lot of very careful work to split even across a small number of well-interconnected general cpus. e.g. the vast zoo of bespoke matrix decompositions for extremely specific subcases.

ultrafilter posted:That's not changing any time soon. the main thing here is restrictions on pointer aliasing and you can do that in c with "restrict" and get the same performance. i think it's more that much fortran code is straight textbook math, "formula translation" as they say, and it's battle tested and works fast so why rewrite it in c and risk loving it up

it is easy to get in a mindset where one imagines that the code would be easy to work with if it was just structured just so (or written in ones preferred language), but some code just expresses sufficiently complicated concepts that it will always be difficult. godspeed etc. v v

i guess in the space future there is no gravity so the bra is actually just there to keep boobs *down* so they dont float away or whatever so that leads to a reverse cleavage paradigm

dumb serious question. why do we use nonlinear functions instead of linear ones if they're all dumb poo poo like ReLU which seems like it barely works. I guess second question: is there any theoretical basis for why ReLU works at all?
