World Age in Julia: Optimizing Method Dispatch in the Presence of Eval (Extended Version) [article]

Julia Belyakova, Benjamin Chung, Jack Gelinas, Jameson Nash, Ross Tate, Jan Vitek
2020 arXiv   pre-print
This paper provides the first formal semantics of world age in a core calculus named Juliette, and shows how world age enables compiler optimizations, such as inlining, in the presence of eval.  ...  The Julia programming language introduces the novel concept of world age to insulate optimized code from one of the most disruptive side-effects of eval: changes to the definition of an existing function  ...  WORLD AGE IN JULIA The world-age mechanism in Julia limits the set of methods that can be invoked from a given call site.  ...

Type Stability in Julia: Avoiding Performance Pathologies in JIT Compilation (Extended Version) [article]

Artem Pelenitsyn, Julia Belyakova, Benjamin Chung, Ross Tate, Jan Vitek
2021 arXiv   pre-print
Success in that niche hinges on fostering a rich ecosystem of highly optimized mathematical libraries.  ...  The Julia language is predicated on the bet that its users can write efficient numerical code in the language itself, without having to resort to C or Fortran.  ...  Notably, due to the so-called world-age mechanism [Belyakova et al. 2020] which restricts the effect of eval, source methods are fixed from the perspective of compilation; only compiled instances changes  ...

Modeling an integrated energy transformation of the electricity sector [article]

Jens Weibezahn, Technische Universität Berlin, Christian Von Hirschhausen
Part II deals with economic dispatch modeling. In Chapter 3 a five-fold approach to open science is introduced and the advantages of open energy models are being discussed.  ...  However, overall network congestion and re-dispatch levels increase in 2015 and also remain on a high level in case of two bidding zones.  ...  Julia can be used in a REPL (read-eval-print loop) on a console, in Jupyter notebooks, and in IDEs like the Atom text editor.  ...
