machine instruction-by-instruction. This enables it to provide arbitrarily detailed observations about what transpired on the system, even in the presence of non-deterministic attacks and executions. ReVirt adds reasonable time and space overhead. Overheads due to virtualization are imperceptible
Behavioral theories and the neurophysiology of reward,
- Annu. Rev. Psychol.
, 2006
"... ■ Abstract The functions of rewards are based primarily on their effects on behavior and are less directly governed by the physics and chemistry of input events as in sensory systems. Therefore, the investigation of neural mechanisms underlying reward functions requires behavioral theories that can ..."

-directed approach behavior, and decision making under uncertainty. Individual neurons can be studied in the reward systems of the brain, including dopamine neurons, orbitofrontal cortex, and striatum. The neural activity can be related to basic theoretical terms of reward and uncertainty, such as contiguity
Active Storage For Large-Scale Data Mining and Multimedia
, 1998
"... The increasing performance and decreasing cost of processors and memory are causing system intelligence to move into peripherals from the CPU. Storage system designers are using this trend toward "excess" compute power to perform more complex processing and optimizations inside stora ..."

On trustworthiness of CPU usage metering and accounting
- Distributed Computing Systems Workshops (ICDCSW), 2010 IEEE 30th International Conference on
, 2010
"... Abstract—In the envisaged utility computing paradigm, a user taps a service provider’s computing resources to accom-plish her tasks, without deploying the needed hardware and software in her own IT infrastructure. To make the service profitable, the service provider charges the user based on the res ..."

In this paper, we provide a systematic study on the trustworthiness of CPU usage metering. Our results show that the metering
Putting the user in direct control of cpu scheduling
, 2006
"... CPU scheduling to enforce service-level agreements (SLAs) is a problem of key importance in service-oriented systems. For services whose ultimate customers are naive end-users, it is often a significant challenge simply to determine the terms of the SLA. We propose a new approach to both SLA specifi ..."

Generation of hardware modules for run-time reconfigurable hybrid CPU/FPGA systems
"... Abstract — This paper describes a tool that creates partially-reconfigurable modules from the bitstreams of individual com-ponent modules. The resulting modules are intended for use in applications that exploit partial dynamic reconfiguration. The tool is integrated in a design flow particularly aim ..."

RT-OpenStack: CPU Resource Management for Real-Time Cloud Computing
"... Abstract—Clouds have become appealing platforms for not only general-purpose applications, but also real-time ones. How-ever, current clouds cannot provide real-time performance to virtual machines (VMs). We observe the demand and the ad-vantage of co-hosting real-time (RT) VMs with non-real-time (r ..."

This paper presents RT-OpenStack, a cloud CPU resource management system for co-hosting real-time and regular VMs. RT-OpenStack entails three main contributions: (1) integration of a real-time hypervisor (RT-Xen) and a cloud management system (OpenStack) through a real-time resource interface; (2
CPU Scheduling for Statistically-Assured Real-Time Performance and Improved Energy Efficiency

We consider CPU scheduling that (1) provides assurances on individual and collective application timeliness behaviors and (2) maximizes system-level timeliness and energy
CPU Gradients: Performance-aware Energy Conservation in Multitier Systems
