Performance search engine driven by prior knowledge of optimization
For scientific array-based programs, optimization for a particular target platform is a hard problem. There are many optimization techniques such as (semantics-preserving) source...

Synthesis of machine code from semantics
In this paper, we present a technique to synthesize machine-code instructions from a semantic specification, given as a Quantifier-Free Bit-Vector (QFBV) logic formula. Our tech...

Composing concurrency control
Concurrency control poses significant challenges when composing computations over multiple data-structures (objects) with different concurrency-control implementations. We formal...

Helium: lifting high-performance stencil kernels from stripped x86 binaries to halide DSL code
Highly optimized programs are prone to bit rot, where performance quickly becomes suboptimal in the face of new hardware and compiler techniques. In this paper we show how to auto...

Droidel: a general approach to Android framework modeling
We present an approach and tool for general-purpose modeling of Android for static analysis. Our approach is to explicate the reflective bridge between the Android framework and ...

Making numerical program analysis fast
Numerical abstract domains are a fundamental component in modern static program analysis and are used in a wide range of scenarios (e.g. computing array bounds, disjointness, etc)...

A formal C memory model supporting integer-pointer casts
The ISO C standard does not specify the semantics of many valid programs that use non-portable idioms such as integer-pointer casts. Recent efforts at formal definitions and veri...

Autotuning algorithmic choice for input sensitivity
A daunting challenge faced by program performance autotuning is input sensitivity, where the best autotuned configuration may vary with different input sets. This paper presents ...

Verifying read-copy-update in a logic for weak memory
Read-Copy-Update (RCU) is a technique for letting multiple readers safely access a data structure while a writer concurrently modifies it. It is used heavily in the Linux kernel ...
