【 摘 要 】

Virtualization via dynamic binary translation is essentially an emulator. The main advantage is that the CPUof the guest does not have to be the same as the CPU ofthe host. Although, dynamic binary translators (DBT) aregaining popularity and offering a promising future in themodern virtual executive environments, the requirementsof DBTs’ processing and memory resources have seriously hampered the performance of host platforms. For cloudcomputing seems to offer incredible lightning-quick processing power and unlimited storage. In this paper, we propose a novel distributed DBT system-DistriBit for resource-limited thin clients computing. Meanwhile, we study the effects of the number of virtual registersand trace length to improve the performance of DistriBit.Our results demonstrate that improving these two factors(the number of virtual registers and trace length) may helpto improve program speedup by up to 1.4to3.9x and 2to3xfor certain benchmark programs.
