6. Compiler-Based Approaches to Reduce Memory. Access Penalties in Cache Coherent Multiprocessors
Abstract : To reduce the average time needed to perform a read or a write access in a multiprocessor, a cache is associated with each processor. A hardware mechanism is used to ensure that the replicated cache copies are consistent. This mechanism employs a protocol which controls when a node may read and/or write a shared data item.

7. Lock-Based Resource Sharing for Real-Time Multiprocessors
Abstract : Embedded systems are widely used in the industry and are typically resource constrained, i.e., resources such as processors, I/O devices, shared buffers or shared memory might be limited in the system. Hence, techniques that can enable an efficient usage of processor bandwidths in such systems are of great importance. READ MORE

8. Resource Sharing in Real-Time Systems on Multiprocessors
Abstract : In recent years multiprocessor architectures have become mainstream, and multi-core processors are found in products ranging from small portable cell phones to large computer servers. In parallel, research on real-time systems has mainly focused on traditional single-core processors. READ MORE

9. Scheduling techniques to improve the worst-case execution time of real-time parallel applications on heterogeneous platforms
Abstract : The key to providing high performance and energy-efficient execution for hard real-time applications is the time predictable and efficient usage of heterogeneous multiprocessors. However, schedulability analysis of parallel applications executed on unrelated heterogeneous multiprocessors is challenging and has not been investigated adequately by earlier works. READ MORE

10. Performance Prediction and Improvement Techniques for Parallel Programs in Multiprocessors
Abstract : The performance of a computer system is important. One way of improving performance is to use multiprocessors with several processors that can work in parallel. Where multiprocessors are used, the programs must also be parallel in order to achieve high performance. READ MORE
