In this paper, we show that it is possible to increase the message throughput of a large-scale industrial system by selectively compress messages. The demand for new high-performance message processing systems conflicts with the cost effectiveness of legacy systems. The result is often a mixed environment with several concurrent system generations. Such a mixed environment does not allow a complete...
Information and Communication Technology (ICT) has led to an unprecedented development in almost all areas of human life. It forms the basis for what is called "the cognitive revolution" -- a fundamental change in the way we communicate, feel, think and learn based on an extension of individual information processing capacities by communication with other people through technology. This...
Large infrastructure systems with a life time of more than 30 years, such as telecommunication or power transmission systems, are difficult to maintain since they suffer from the end-of-life plague of software, hardware and knowledge. Large companies have traditionally tackled this problem successfully, but maybe not with complete efficiency in all cases. We find system evolution to be an increasingly...
Communication is a vital part of computer systems today. One current problem is that computational capacity is growing faster than the bandwidth of interconnected computers. Maximising performance is a key objective for industries, both on new and existing software systems, which further extends the need for more powerful systems at the cost of additional communication. Our contribution is to let...
Memory contention is one of the largest sources of inter-core interference in statically partitioned multicore systems, and the contention reduces the overall performance of applications and causes unpredictable execution-times. A first step in achieving predictable execution is to accurately measure the amount of consumed memory bandwidth for each application. Such measurements can be used to track...
