XLDI 2012

First International Workshop on
Cross-model Language Design and Implementation
Affiliated with ICFP 2012, Copenhagen, Denmark

Sponsored by ACM SIGPLAN

September 9, 2012 (Sunday before ICFP)
Submission site (now closed)

There has recently been a burst of systems research advocating high-performance commodity “big data” or “massively parallel” computing models, often using simpler high-level languages or interfaces as front-ends. This work is often described as part of a shift towards a new “cloud computing” paradigm, but these buzzwords mask the major problems these techniques face: both big data and massively parallel systems currently employ systems-based methods and testing regimes that cannot offer guarantees of safety, security, correctness and evolvability. Language-based techniques, particularly formalization, verification, abstraction, and representation independence, offer the promise to reconcile the performance benefits of new execution models with the advantages of modern programming languages.

Cross-model programming is not a new problem: for example, smooth integration of relational database programming models into general-purpose programming languages has been a long-standing challenge, with some approaches now in mainstream use (such as Microsoft's LINQ). But in the last few years there has been a dramatic increase in the number of domain-specific languages or libraries for interfacing with different computing models (data-parallelism, sensor networks, MapReduce-style fault-tolerant parallelism, distributed programming, Bayesian inference engines, declarative networking, or multi-tier Web programming), as well as techniques for language-integrated querying or processing data over other data models. Cross-model programs that execute in multiple (possibly heterogeneous) environments have much more challenging security, debugging, validation, and optimization problems.
