Validation of distributed systems using fault injection is difficult because of their inherent complexity, lack of a global clock, and lack of an easily accessible notion of a gl...

We study the problem of dynamic spectrum sensing and access in cognitive radio systems as a partially observed Markov decision process (POMDP). A group of cognitive users cooperati...

We are designing dynamic analysis techniques to identify executed program statements where a fault lies, i.e. the fault candidate set. To narrow the set of statements in the fault...
This paper reports on the architecture and design of Starfish, an environment for executing dynamic (and static) MPI-2 programs on a cluster of workstations. Starfish is unique in ...
— This paper presents Salsa, a novel, decentralized and asynchronous realization of the “replica exchange” algorithm for simulating the structure, function, folding, and dyna...
