IPC: F04C14/24
Filed: 2007-09-26
Abstract: A pump system includes pump having a control feature which, responsive to a supply of pressurized working fluid, reduces the pressure of the working fluid pressurized by the pump. The control feature is connected to the output of the pump by a regulating valve. The control feature receives pressurized working fluid to decrease the output of the pump in response to the pressure of the supplied working fluid. A regulating valve selectively connects the pressurized working fluid to the control feature. The regulating valve has a control port to receive pressurized working fluid from the pump to urge the valve to a closed position against a biasing force. A controllable valve is operable to interrupt the supply of pressurized working fluid to control port to alter the output pressure of the pump.

Title: Managing speculative assist threads
Inventor: ARCHAMBAULT ROCH G
IPC: G06F9/44
Filed: 2009-10-16
Abstract: An illustrative embodiment provides a computer-implemented process for managing speculative assist threads for data pre-fetching that analyzes collected source code and cache profiling information to identify a code region containing a delinquent load instruction and generates an assist thread, including a value for a local version number, at a program entry point within the identified code region. Upon activation of the assist thread the local version number of the assist thread is compared to the global unique version number of the main thread for the identified code region and an iteration distance between the assist thread relative to the main thread is compared to a predefined value. The assist thread is executed when the local version number of the assist thread matches the global unique version number of the main thread, and the iteration distance between the assist thread relative to the main thread is within a predefined range of values.
