Description

Update: The timetable is available now.

This meeting aims to introduce and discuss framework-independent analysis description language concepts and implementations for LHC physics analyses. An analysis description language (ADL) is a human readable format capable of describing the contents of an analysis in a standard and unambiguous way, independent of any computing framework. Adapting ADLs would have numerous benefits for the LHC community, ranging from analysis preservation that goes beyond the lifetimes of experiments or analysis software, to facilitating the abstraction, design, visualization, validation, combination, reproduction, interpretation and overall communication of the contents of LHC analyses. ADLs can be used both by the experimental and phenomenological communities. Several attempts were made recently to develop ADLs and generic interpreters for those. A recent effort is in progress to merge the existing approaches and bring forward a unified ADL syntax. 

The meeting will motivate the ADL concept, present the current proposal, and have technical discussions on language structure, parsing and interpretation methods.  Hands on sessions will focus on studying and running existing analysis implementations, and on implementing new analyses proposed by the participants.  A special discussion will be held on the feasibility of ADLs for direct use in analyses with ATLAS and CMS data.

The workshop is open to all interested experimentalists, phenomenologists and computing specialists.

      Fermilab colloquium : Particle physics and programming languages 1h Wilson Hall (Fermilab)

      Wilson Hall

      Fermilab

      Programming languages aren't for computers; they're for people. If a language doesn't make it easier to express your physics problem, it's not a suitable language. Some fields have specialized "Domain Specific Languages" (DSLs) that trade freedom of expression for focus on the problem at hand, and can even improve performance by limiting this scope. A prime example is SQL, widely used by data analysts outside of physics, which trades generic computation for a SELECT-WHERE-GROUPBY pattern. Interestingly, this was the design pattern of the first electromechanical computers (Hollerith machine, 1890) and it's still a major focus of big data today (Dean & Ghemawat: MapReduce, 2004). Particle physics problems don't fit SQL well; in fact, physicists became involved in computing in tandem with the invention of generic, digital computers (Von Neumann's stored-program machine, 1945). I will present some history, some general features of programming languages, what "declarative" really means, and will show some perhaps surprising examples of DSLs you're already using.
