SLEEP STATE MECHANISM FOR VIRTUAL MULTITHREADING

Method, apparatus and system embodiments provide support for multiple SoEMT software threads on multiple SMT logical thread contexts. A sleep state mechanism maintains a current value of an element of architecture state for each physical thread. The current value corresponds to an active virtual thread currently running on the physical thread.

Upon a read of the architecture state element, simplified mux logic selects among the current values to provide the current value for the appropriate active thread. Upon a thread switch, control logic associated with the sleep state mechanism swaps the active state value for the current thread with the inactive state value for the new thread.

Network utilization of an arbitrary application is controlled by tracking network usage statistics of virtual machines (VMs), including at least VMs hosting parts of the application. For network utilization control, VMs serve as network proxies for elements of the application. A specification for a network requirement of the application is evaluated against the network usage statistics.

Or, for example, network bandwidth availability for an under-requirement VM may be increased and bandwidth availability for a VM at an appropriate host or network location may be decreased. Thus, application-level communication path requirements may be satisfied using VM adaptations.
