Testing the interaction between hard- and software is only possible once prototype implementations of the hardware exist. HDL simulations of hardware models can help to find defects in the hardware design. To predict the behavior of entire software stacks in the environment of a complete system, virtual machines can be used. Combining a virtual machine with HDL-simulation enables to project the interaction...
Virtualization enables multiple guest operating systems run on a single physical platform. These virtual machines may host any types of application, including concurrent HPC programs. Traditionally, VMM schedulers have focused on fairly sharing the processor resources among domains, rarely consider VCPUs' behaviors. However, this can result in poor application performance to overcommitted domains...
This paper surveys virtualization of I/O devices, which is one of the most difficult parts in system virtualization. Current technologies of virtualizing I/O devices include full virtualization, paravirtualization, software emulation and VMM-bypass direct I/O. Optimizations are also done to improve the performance of each technology. Most optimizations used paravirtualization technology for reference...
Java is dominating in object-oriented computing. However, Java relies on Java Virtual Machine to process Java bytecodes, such that it imposes large overhead on the embedded system. In addition, as security is always a major concern in most of the networked computer systems, embedded systems should provide security features to defend against attacks. Many viruses use the security loopholes to trigger...
The virtualization technology has been developed rapidly with the growth of the hardware supported virtualization technologies and the appearance of the various services. Many researchers are concentrating on developing the virtualization technologies which are recognized as the most significant core technology of the IT applications such as green IT and cloud computing. The major processor companies...
Business continuity is valuable to IT management in both small and large organizations. As faults, errors, and even disasters perfectly exist, instantaneous service fail over must be furnished to computer systems in order to preserve business continuity. However, current solutions concentrate either on volatile memory and CPU context or on persistent disk storage, instantaneous fail over can hardly...
Virtualization has proven to be a powerful technique used for resource partitioning and resource aggregation. Although this concept has been widely utilized in cluster computing, distributed systems and system consolidation; it has not been equally applied to improve performance of commodity operating systems and applications. This paper introduces a client-driven paradigm for harnessing specific...
The architecture of modern computing systems is getting more and more parallel, in order to exploit more of the offered parallelism by applications and to increase the system's overall performance. This includes multiple cores per processor module, multi-threading techniques and the resurgence of interest in virtual machines. In spite of this amount of parallelism the network interface is typically...
