Increased levels of automation together with increased complexity of automation systems brings increased responsibility on the system developers in terms of quality demands from the legal perspectives as well as company reputation. Component based development of software systems provides a viable and cost-effective alternative in this context provided one can address the quality and safety cert...

A new paradigm for an all-to-all optical interconnect is presented. It could be part of an interconnection fabric between parallel processing elements and the first level of the cache in a computer system. Parallel processing has traditionally aspired to improve performance of such systems. An optical interconnect raises a new possibility: obtain both improved performance and significant cost r...

Most cloud computing optimizers explore and improve one workload at a time. When optimizing many workloads, the single-optimizer approach can be prohibitively expensive. Accordingly, we examine “collective optimizer” that concurrently explore and improve a set of workloads significantly reducing the measurement costs. Our large-scale empirical study shows that there is often a single cloud conf...
