Heterogeneous CPU-GPU system is a powerful way to accelerate compute-intensive applications, such as the subset-sum problem. Many parallel algorithms for solving the problem have been implemented on graphics processing units (GPUs). However, these GPU implementations may fail to fully utilize all the CPU cores and the GPU resources. When the GPU performs computational task, only one CPU core is...

Virtualization is used to ease computing resource management, resource utilization and running multiple heterogeneous or homogeneous operating systems on a single physical machine. Virtualization offers many advantages such as reducing fiscal costs, easing system migration, running legacy applications, easing backups and disaster recovery, and utilizing the shared resources over traditional dat...

Techniques for predicting the availability of CPU resources associated with the execution of multiple concurrent Java threads on a multi-core architecture are introduced. Prediction of CPU availability is important in the context of making thread assignment and scheduling decisions. Theoretically derived upper and lower bound formulas for estimating CPU availability are introduced. Input parame...

Performance of a Java Virtual Machine (JVM) is quantified in terms of the JVM’s relative CPU availability at executing concurrent Java threads. The total CPU loading of a JVM is defined by the sum of the CPU utilization factors of all threads executing on the JVM. Sharp performance degradation has been observed while JVM executes concurrent threads with exactly same CPU load. An analytical mode...

The Computer Measurement Group, commonly called CMG, is a not for profit, worldwide organization of data processing professionals committed to the measurement and management of computer systems. CMG members are primarily concerned with performance evaluation of existing systems to maximize performance (eg. response time, throughput, etc.) and with capacity management where planned enhancements ...
