Publication number: 20160224324Abstract: Provided are methods and systems for inter-procedural optimization (IPO). A new IPO architecture (referred to as “ThinLTO”) is designed to address the weaknesses and limitations of existing IPO approaches, such as traditional Link Time Optimization (LTO) and Lightweight Inter-Procedural Optimization (LIPO), and become a new link-time-optimization standard. With ThinLTO, demand-driven and summary-based fine grain importing maximizes the potential of Cross-Module Optimization (CMO), which enables as much useful CMO as possible ThinLTO also provides for global indexing, which enables fast function importing; parallelizes some performance-critical but expensive inter-procedural analyses and transformations; utilizes demand-driven, lazy importing of debug information that minimizes memory consumption for the debug build; and allows easy integration of third-party distributed build systems. In addition, ThinLTO may also be implemented using an IPO server, thereby removing the need for the serial step.Type: ApplicationFiled: February 27, 2015Publication date: August 4, 2016Applicant: GOOGLE INC.Inventors: Xinliang David LI, Teresa Louise JOHNSON, Rong XU

Publication number: 20150285031Abstract: A technique facilitates the anchoring and use of a downhole tool. The technique may be utilized with operations in which fluid is pumped or otherwise flowed through a tubular to the downhole tool. The operations are performed after the downhole tool has been fixed relative to the wellbore and while the tubular remains connected to the downhole tool. In some operations, the downhole tool is manipulated from the surface via the tubular to control placement of the fluid flowing down through the tubular.Type: ApplicationFiled: November 21, 2013Publication date: October 8, 2015Inventors: Michael Hayes Kenison, Zheng Rong Xu, Jeffrey Conner McCabe, Robert Bucher

Patent number: 8857526Abstract: A mechanism configured for mechanical self-deployment in a well. The mechanism may be primarily an open or closed-cell polymer foam positioned downhole in a pre-compressed state. Subsequently, the mechanism may be released from a housing for self-deployment and engagement with a wall of the well. Such a mechanism may serve the conventional purpose of a downhole packer or other similar restriction devices. Additionally, due to the self-deploying nature of the device, multiple such devices may be linked in series based upon user-determined criteria at the time of application. Thus, a reduction in the number of trips in the well may generally be realized.Type: GrantFiled: April 26, 2010Date of Patent: October 14, 2014Assignee: Schlumberger Technology CorporationInventors: Zafer Erkol, Zheng Rong Xu, Ian Crossland

Patent number: 8186437Abstract: An assembly for delivery of treatment fluid at a target location downhole. The assembly is configured to avoid any substantial loss of treatment fluid in advance of reaching the target location in spite of low well pressure or a potentially excessive depth of the location. The assembly also allows for loading with treatment fluid from a downhole end thereof so as to avoid driving treatment fluid through the entirety of a tubular accommodating the assembly. The assembly may employ a spot valve to enhance filling with treatment fluid along with a backpressure valve coupled to the spot valve on-site so as to avoid premature loss of treatment fluid during a delivery application.Type: GrantFiled: November 30, 2009Date of Patent: May 29, 2012Assignee: Schlumberger Technology CorporationInventors: Zheng Rong Xu, Jorge A.

Patent number: 8158405Abstract: A method of treating a liquid sample having microbiological target species therein to concentrate the species and collect lysate is disclosed. The liquid sample comprises non-target microbiological particles, inorganic particles, and microbiological target species. The liquid is passed through a prefilter medium to allow the target species to pass through as filtrate and retain non-target microbiological products and inorganic particles thereon. The filtrate is contacted with a main filtration medium adapted to retain the target species thereon as retentate. The retentate is lysed to form a lysate containing target material that was enveloped within the microbiological target species. The microbiological species may comprise cell containing or viral material. Target materials comprise intracellular nucleic acids, or in the case of viral sampling, nucleic acids encased within the protein sheath or coating of the virus.Type: GrantFiled: June 30, 2008Date of Patent: April 17, 2012Assignee: General Electric CompanyInventors: Scott Boyette, Rong Xu, Jing Luo, Weiqing Xu, Jing Chen, Weimin Xiao, Tong Chen
