The goal of this paper is to study attitude stability in schizophrenics' relatives, as reflected in the expressed emotion (EE) construct. For this purpose, the EE of 32 families of schizophrenic patients was assessed by means of the Camberwell Family Interview (CFI, Brown, Birley, & Wing, 1972; Vaughn & Leff, 1976b), both initially and at a 9-month(More)
SUMMARY With the evolution of high-performance computing towards heterogeneous, massively parallel systems, parallel applications have developed new checkpoint and restart necessities. Whether due to a failure in the execution or to a migration of the application processes to different machines, checkpointing tools must be able to operate in heterogeneous(More)

We strive to make our products available in a variety of formats and(More)
SUMMARY This paper presents CPPC (Controller/Pre-compiler for Portable Checkpointing), a checkpointing tool designed for heterogeneous clusters and Grid infrastructures through the use of portable protocols, portable checkpoint files and portable code. It works at variable level being user-directed, thus generating small checkpoint files. It allows parallel(More)
The running times of large–scale computational science and engineering parallel applications, executed on clusters or Grid platforms, are usually longer than the mean–time– between–failures (MTBF). Hardware failures must be tolerated by the parallel applications to ensure that no all computation done is lost on machine failures. Checkpoint-ing and rollback(More)
Checkpointing tools may be typically implemented at two different abstraction levels: at the system level or at the application level. The latter has become a more popular alternative due to its flexibility and the possibility of operating in different environments. However, application-level checkpointing tools often require the user to manually insert(More)
One of the key functionalities provided by Grid systems is the remote execution of applications over the Grid. We present a research proposal on fault-tolerance mechanisms for the execution of message-passing parallel applications on the Grid. An architecture called CPPC-G is proposed, consisting of a set of services built on top of the Globus Toolkit. The(More)
A 1 trillion node internet of things (IoT) will require sensing platforms that support numerous applications using power harvesting to avoid the cost and scalability challenge of battery replacement in such large numbers. Previous SoCs achieve good integration and even energy harvesting [1][2][3], but they limit supported applications, need higher(More)
