Delayed caching receives an evaluation interval to delay updating the objects stored in a delayed cache, delays a time period corresponding to the evaluation interval, and updates the objects stored in the contents of the delayed cache when the time period delay has completed. The configuration operation for the delayed cache selects a time interval to sample a trace having object access frequencies for objects stored in a cache, creates a first working set of objects accessed during the time interval and a second working set of objects accessed during a subsequent time interval based on the historical trace, determines that the difference between the objects contained in the first and second working sets does not exceed a maximum threshold with the selected time interval, and sets a evaluation interval for evaluating the contents of the cache to the selected time interval.

Prior to or while the state of a virtual machine (“VM”) is being saved, such as in connection with the suspension or checkpointing of a VM, a set of one or more “active” memory pages is identified, this set of active memory pages comprising memory pages that are in use within the VM before operation of the VM is suspended.

By exploiting an early release facility that may be provided by certain transactional memory designs, we allow for transaction software constructs that wait on removal (or satisfaction) of a condition that would otherwise result in transaction abort. Absent exploitation of such a such a facility, the act of checking the condition would typically introduce a corresponding location into the read set of the transaction, and a subsequent modification of that location that removed (or satisfied) the condition, would result in abortion of the blocked transaction. By exploiting an early release facility such as described herein, a transaction may release the location (or locations) corresponding the condition, retry, and once the transient condition is removed (or satisfied), complete and commit. In this way, computation effort may be conserved while still employing a conceptually simple and convenient coordination facility.
