Reconfigurable Drone System for Transportation of Parcels With Variable Mass and Size

Dario Floreano, Fabrizio Schiano, Przemyslaw Mariusz Kornatowski, Leonardo Cencetti

Cargo drones are designed to carry payloads with predefined shape, size, and/or mass. This lack of flexibility requires a fleet of diverse drones tailored to specific cargo dimensions. Here we propose a new reconfigurable drone based on a modular design th ...

New Capabilities of the FLUKA Multi-Purpose Code

Nikolaos Charitonidis, André Donadon Servelle, Philippe Jean Schoofs, Francesco Cerutti

FLUKA is a general purpose Monte Carlo code able to describe the transport and interaction of any particle and nucleus type in complex geometries over an energy range extending from thermal neutrons to ultrarelativistic hadron collisions. It has many diffe ...

Gramatron: Effective Grammar-Aware Fuzzing

Mathias Josef Payer

Fuzzers aware of the input grammar can explore deeper program states using grammar-aware mutations. Existing grammar-aware fuzzers are ineffective at synthesizing complex bug triggers due to: (i) grammars introducing a sampling bias during input generation ...

Scaling Functional Synthesis and Repair

Emmanouil Koukoutos

Program synthesis was first proposed a few decades ago, but in the last decade it has gained increased momentum in the research community. The increasing complexity of software has dictated the urgent need for improved supporting tools that verify the soft ...

Shrink It or Shed It! Minimize the Use of LSQs in Dataflow Designs

Paolo Ienne, Andrea Guerrieri, Lana Josipovic, Atri Bhattacharyya

When applications have unpredictable memory accesses or irregular control flow, dataflow circuits overcome the limitations of statically scheduled high-level synthesis (HLS). If memory dependences cannot be determined at compile time, dataflow circuits rel ...

Techniques for Detection, Root Cause Diagnosis, and Classification of In-Production Concurrency Bugs

Baris Can Cengiz Kasikci

Concurrency bugs are at the heart of some of the worst bugs that plague software. Concurrency bugs slow down software development because it can take weeks or even months before developers can identify and fix them. In-production detection, root cause ...

Automatic generation of program execution that reaches a given failure point

George Candea, Cristian Zamfir

An execution of a target software program that causes a particular bug to manifest itself is generated. A target software program is received. A bug report generated by an execution of the target software program is received. The bug report describes a par ...

Automated Debugging for Arbitrarily Long Executions

George Candea, Edouard Bugnion, Johannes Kinder, Cristian Zamfir, Baris Can Cengiz Kasikci

One of the most energy-draining and frustrating parts of software development is playing detective with elusive bugs. In this paper we argue that automated post-mortem debugging of failures is feasible for real, in-production systems with no runtime record ...

Execution Synthesis: A Technique for Automating the Debugging of Software

Cristian Zamfir

Debugging real systems is hard, requires deep knowledge of the target code, and is time-consuming. Bug reports rarely provide sufficient information for debugging, thus forcing developers to turn into detectives searching for an explanation of how the prog ...

Fast black-box testing of system recovery code

George Candea, Radu Banabic

Fault injection-a key technique for testing the robustness of software systems-ends up rarely being used in practice, because it is labor-intensive and one needs to choose between performing random injections (which leads to poor coverage and low represent ...

Striking a New Balance Between Program Instrumentation and Debugging Time

Willy Zwaenepoel, Olivier Crameri, Ricardo Bianchini

Although they are helpful in many cases, state-of-the-art bug reporting systems may impose excessive overhead on users, leak private information, or provide little help to the developer in locating the problem. In this paper, we explore a new approach to b ...

Exterminating Bugs via Collective Information Recycling

George Candea

End-user software is executed billions of times daily, but the corresponding execution details (“by-products”) are discarded. We hypothesize that, if suitably captured and aggregated, these by-products could substantially speed up the process of testing pr ...

Finding Almost-Invariants in Distributed Systems

Dejan Kostic, Marco Canini, Maysam Yabandeh

It is notoriously hard to develop dependable distributed systems. This is partly due to the difficulties in foreseeing various corner cases and failure scenarios while implementing a system that will be deployed over an asynchronous network. In contrast, r ...

Debugging real systems is hard, requires deep knowledge of the code, and is time-consuming. Bug reports rarely provide sufficient information, thus forcing developers to turn into detectives searching for an explanation of how the program could have arrive ...
