Abstract
Official abstract text for this publication.
Various aspects are disclosed herein for attenuating spin waiting in a virtual machine environment comprising a plurality of virtual machines and virtual processors. Selected virtual processors can be given time slice extensions in order to prevent such virtual processors from becoming de-scheduled (and hence causing other virtual processors to have to spin wait). Selected virtual processors can also be expressly scheduled so that they can be given higher priority to resources, resulting in reduced spin waits for other virtual processors waiting on such selected virtual processors. Finally, various spin wait detection techniques can be incorporated into the time slice extension and express scheduling mechanisms, in order to identify potential and existing spin waiting scenarios.
First claim
Opening claim text (preview).
What is claimed: 1. A method for attenuating spin waiting of virtual processors in a virtual machine environment, comprising: examining a hint source for hints to determine if a virtual processor is accessing a synchronizing section that acquires a lock on an underlying physical resource that causes any other virtual processors to spin wait until said virtual processor releases the lock; wherein said synchronizing section is a region of code that determines access to resources b…
