The realization of VTS using virtual machine VM technology offers several benefits including fidelity, scalability, interoperability, fault tolerance and load balancing. The former is prevalent in high-fidelity cyber infrastructure simulations and cyber-physical system simulations, wherein VMs form a crucial component of VTS.
The latter appears in the popular Cloud computing services, where VMs are offered as computing commodities and the VTS utilizes VMs as parallel execution platforms.
Prior to our work presented sixt bitcoins und andere dezentrale transactionsystemesysteme, the simulation community using VM within VTS specifically, cyber infrastructure simulations had little awareness of the existence of a fundamental virtual time-ordering problem. The correctness problem was largely unnoticed and unaddressed because of the unrecognized effects of fair-share multiplexing of VMs to realize virtual time evolution of VMs within VTS.
The dissertation research reported here demonstrated the latent incorrectness of existing methods, defined key correctness benchmarks, quantitatively measured the incorrectness, proposed and implemented novel algorithms to overcome incorrectness, and optimized the solutions to execute without a performance penalty.
In fact our novel, correctness-enforcing design yields better runtime performance than the traditional incorrect methods. Similarly, the Bitcoin maximum execution over VM platforms such as Cloud computing services incurs large performance degradation, which was not known until our research uncovered the fundamental mismatch between the scheduling needs of VTS execution and those of traditional parallel workloads.
VTS follows virtual-time order execution whereas the conventional VM execution follows fair-share policy. Moreover, we proposed and implemented a novel virtual time-aware execution methodology that relieves the degradation and provides over an order of magnitude faster execution than the traditional virtual time-unaware execution.
