Fast Energy Estimation Through Partial Execution of HPC Applications

Marina Zapater Sancho, José Luis Ayala Rodrigo

In order to optimize the energy use of servers in Data Centers, techniques such as power capping or power budgeting are usually deployed. These techniques rely on the prediction of the power and execution time of applications. These data are obtained via d ...

The Complexity of Reliable and Secure Distributed Transactions

Junxiong Wang

The use of transactions in distributed systems dates back to the 70's. The last decade has also seen the proliferation of transactional systems. In the existing transactional systems, many protocols employ a centralized approach in executing a distributed ...

Parallel symbolic execution on cluster of commodity hardware

George Candea, Cristian Zamfir, Stefan Bucur

A symbolic execution task is dynamically divided among multiple computing nodes. Each of the multiple computing nodes explores a different portion of a same symbolic execution tree independently of other computing nodes. Workload status updates are receive ...

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 ...

Symbolic execution of Reo circuits using constraint automata

Hossein Hojjat

Reo is a coordination language that can be used to model different systems. We propose a technique for symbolic execution of Reo circuits using the symbolic representation of data constraints in Constraint Automata. This technique enables us to obtain the ...

Striking a New Balance Between Program Instrumentation and Debugging Time

Willy Zwaenepoel, Ricardo Bianchini, Olivier Crameri

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 ...

A Data-oriented Transaction Execution Engine and Supporting Tools

Anastasia Ailamaki, Miguel Sérgio De Oliveira Branco, Frederick Ryan Johnson, Pinar Tözün, Ippokratis Pandis, Danica Porobic, Dimitrios Karampinas

Conventional OLTP systems assign each transaction to a worker thread and that thread accesses data, depending on what the transaction dictates. This thread-to-transaction work assignment policy leads to unpredictable accesses. The unpredictability forces e ...

Debugging by lastChange

Claude Petitpierre, Salman Mirghasemi

Developers often seek the origins of wrong values they see in their debugger. Their search must be backwards in time: the code causing the wrong value executed before the wrong value appeared. Searching with breakpoint- or log- based debuggers demands pers ...
