Because of the ever-increasing data being produced by today's high performance
computing (HPC) scientific simulations, I/O performance is becoming a significant bottleneck …

We present a novel performance modeling approach tailored to I/O performance prediction
in virtualized environments. The main idea is to identify important performance-influencing …

Abstract Coloured Petri Nets formalism is commonly used for modelling various aspects of
communication systems. Simulations of such models facilitate performance evaluation …

With the increasing popularity of virtual machine monitoring (VMM) technologies,
performance variability among collocated virtual machines (VMs) can easily become a …

In a virtualized computer system with shared resources, consolidated virtual services (VSs)
fiercely compete with each other to obtain the required capacity of resources, and this …

Huge requirements of emerging Big Data applications combined with the performance
impairment of current I/O subsystems pose a great challenge on data storage, management …

Cloud storage becomes popular, but low data-access performance through WANs (wide
area networks) is becoming an issue. A cloud-storage cache, called “cloud on-ramp”(CoR) …

Looking at a picture on a screen is very different from looking at a solid object. But if the
picture changes correctly as the observer moves, we can create the illusion that there is a …

The ever-increasing I/O resource demands pose significant challenges for today's system
environments to meet performance requirements. The resource demand effects are even …
