Guaranteeing the system workload within design bounds is a basic requirement for a real-time system. Design-time bounds are usually based on worst-case activation patterns and worst-case execution time. While using the worst-case assumptions for online monitoring can guarantee the system safety, it also introduces unexplored slacks due to tasks consuming less than their worst-case execution times...
The traditional LRU replacement policy is susceptible to memory-intensive workloads with large non-reused data like thrashing applications and scan applications. For such workloads, the majority of cache blocks don't get any cache hits during residing in the cache. Cache performance can be improved by reducing the interference from non-reused data. Therefore, the lifetime of other blocks is increased...
jPredictor is a tool for detecting concurrency errors in Java programs. The Java program is instrumented to emit property-relevant events at runtime and then executed. The resulting execution trace is collected and analyzed by Predictor, which extracts a causality relation sliced using static analysis and refined with lock-atomicity information. The resulting abstract model, a hybrid of a partial...
