Justin, I do not know the answer to this question. Woudl you kindly elaborate further - do you mean is it necessary to have checkpointing with Julia, or are you working on checkpointing software?
Not really an answer to this question. Julia uses the LLVM compiler and something called multiple dispatch. At first sight as a scientist/engineer you will probably throw your hands up in horror at the though of multiple dispatch, and start wailign that it is wasteful of machine resources and CPU cycles. But no, wait and think on... computers are pretty powerful these days and disk space (to a first approcxilmation) is plentiful. SO read on with an open mind... https://armchairecology.blog/2017/07/10/julia-in-ecology-why-multiple-dispatch-is-good/ http://www.stochasticlifestyle.com/type-dispatch-design-post-object-oriented-programming-julia/ So for any function Julia creates separate OPTIMISED code paths for every combination of types the function can operate on. (ie those types which do not have operators which are able to work on them are ruled out). Read that again - instead of creating huge code blocks which work with any type which you give it, separate code blocks with optimised code are produced. (Th is is my understanding of how it works). A consequence of this is that first time through, a Julia program is slow. You are cautioned to remember this when benchmarking. I have never shot a gun, but if I may bowrrow a term from target shooting there is a pretty tight grouping around the C bullseye here https://julialang.org/benchmarks/ Before anyone throws their teddies away, it is of course perfectly possible to produce compiled Julia code. My reading of this is that this is not a slick process at the moment, and there are efforts ongoing to make this easy. Though this looks pretty slick to me: https://github.com/JuliaComputing/static-julia On 18 September 2017 at 04:08, Justin Y.
