In this paper, we present CLUE, a system event analytics tool for black-box performance diagnosis in production Cloud Computing systems. CLUE provides an unified and extensible means of profiling service transactional behaviors, and builds structured data called event sketches. CLUE further offers a set of analytic tools for summarizing and analyzing event sketches by integrating data mining and statistical...
Traditional operating systems differentiate between threads, which are managed by the kernel scheduler, and interrupt handlers, which are scheduled by the hardware. This approach is not only asymmetrical in its nature, but also introduces problems relevant to real-time systems because low-priority interrupt handlers can interrupt high-priority threads. We propose to internally design all threads as...
Lu's chaotic system is founded by Lu and chen in 2002 and its synchronization control can be the kernel technology in chaos-based secure communication. In this paper we propose a scheme's synchronization of Lu's chaotic system with oscillating parameters under the impulsive control. If oscillating parameters approach to 0, we proved that two systems can get synchronized. The chaos-based secure communication...
We are witnessing an increasing adoption of GPUs for performing general purpose computation, which is usually known as GPGPU. The main challenge in developing such applications is that they often do not fit in the model required by the graphics processing devices, limiting the scope of applications that may be benefit from the computing power provided by GPUs. Even when the application fits GPU model,...
Interrupt latency has great impact on the real time and predictability of real-time operating system kernels. In traditional implementation of real-time kernels, interrupts are frequently disabled in system service routines, critical sections, etc., which causes kernel interrupt latency. In this paper we propose a method called PIL (predictive interrupt latency). PIL reduces interrupt latency by never...
Synchronization as the key to parallel and distributed computing requires a robust mechanism to handle communication among concurrent processes. In this paper we propose a flattened parallel simulator for DEVS and Cell-DEVS based on the classical null-message and lookahead based synchronization mechanism. We first present how flattening the architecture reduces communication overheads among participating...
This paper presents CARP, an integrated program and storage replication solution. CARP extends program replication systems which do not currently address storage errors, builds upon a record-and-replay scheme that handles nondeterminism in program execution, and uses a scheme based on recorded program state and I/O logs to enable efficient detection of silent data errors and efficient recovery from...
The synchronization between threads has serious impact on the performance of many-core architecture. When communication is frequent, coarse-grained synchronization brings significant overhead. Thus, coarse-grained synchronization is not suitable for this situation. However, the overhead of fine-grained synchronization is still small when the communication is frequent. For the many-core architecture...
Identifying code implementing a crosscutting concern (CCC) automatically can benefit the maintainability and evolvability of the application. Although many approaches have been proposed to identify potential aspects, a lot of manual work is typically required before these candidates can be converted into refactorable aspects. In this paper, we propose a new aspect mining approach, called clustering-based...
