We propose a framework to estimate the number of timing errors experienced by an application as it runs on timing-speculative processor. It takes hybrid approach combining accurate gate-level dynamic analysis engine find in processor’s control network with fast architecture-level execution-driven simulator based path activation model datapath. develop instruction-level error that estimat...

We use contemporary quantum computers to experimentally investigate steering of an open system by measurements on its environment. On three IBM processors we distinguish a qubit as the and perform pairwise interactions with multiple environment ancillas, following collision model approach. Different measurement strategies ancillas lead different state ensembles system, which are reconstructed e...

This paper is primarily concerned with theoretical evaluation of the performance of multiprocessors system. A markovian waiting line model has been developed for various different multi-processors configurations, with shared memory. The system is analysed at the request level rather than job level.
