Predictable computing in virtualizated distributed computer systems based on partitioning of computation and communication resources

Abstract

The invention relates to a method for providing guaranteed quality of service in distributed computing platforms for execution of distributed applications, by combining: i) a partitioned operating system (POS) or a hypervisor () executed on at least two computers (); where said POS/hypervisor allocates the CPU, memory and I/O hardware resources to computer partitions in said computers; where said computers are capable of executing different computer partitions () with different application tasks within one said computer partition or executing different operating systems (in case of hypervisor) within one said computer partition; wherein the said POS/hypervisor ensures that the application tasks executed in different partitions within the same said computer get their allocated hardware resources; wherein said POS/hypervisor performs a time-driven scheduling for a subset of computer partitions based on a given configuration (), ii) means, for example network communication technology, for implementing partitioning of Ethernet communication resources and creating virtualized networks out of one physical network.
