Patent number: 9547726Abstract: A method for enabling access to a data resource, which is held on a file server (25) on a first local area network (LAN) (21a), by a client (28) on a second LAN (21b). A proxy receiver (48) on the second LAN (21b) intercepts a request for the data resource submitted by the client (28) and transmits a message via a wide area network (WAN) (29) to a proxy transmitter (52) on the first LAN (21a), requesting the data resource. The proxy transmitter (52) retrieves a replica of the data resource from the file server (25) and conveys the replica of the data resource over the WAN (29) to the proxy receiver (48), which serves the replica of the data resource from the proxy receiver (48) to the client (28) over the second LAN (21b).Type: GrantFiled: March 15, 2010Date of Patent: January 17, 2017Assignee: Cisco Technology, Inc.Inventors: Etai Lev Ran, Shahar Glixman, Israel Ben Shaul, Vita Bortnikov, Daniel Kaminsky, Danit Ben Kiki, Idan Zach, Israel Cidon

Patent number: 6785683Abstract: A technique for rapid retrieval and navigation of assets stored on a computer system involves defining a taxonomy and classification rules according to asset-specific criteria, identifying the stored assets, automatically categorizing the identified assets according to the defined classification system, followed by indexing of the categorized assets. A presentation tool is utilized to display and navigate the indexed assets in a first pane, using a tree view having two integrated hierarchies of classified information. The hierarchies can be specific to a programming language or other code assets. All categories of indexed information in which a said selected element is classified is displayed in a second pane.Type: GrantFiled: July 6, 2000Date of Patent: August 31, 2004Assignee: International Business Machines CorporationInventors: Gabi Zodik, Vita Bortnikov, Avi Yaeli

Patent number: 6631518Abstract: Disclosed is a system and method for a profiling system wherein profile data is stored in a separable hierarchical fashion such that profile data for each compiled procedure in a computer program can be readily identified and utilized. In particular, each source module has a corresponding profile data file and each procedure has a corresponding procedure profile area. The system and method also includes a mechanism for verifying the existence and validity of profile information, and a mechanism for handling invalid profile information.Type: GrantFiled: March 19, 1997Date of Patent: October 7, 2003Assignee: International Business Machines CorporationInventors: Vita Bortnikov, David John Lambert, Bilha Mendelson, Robert Ralph Roediger, William Jon Schmidt, Inbal Shavit-Lottem

Patent number: 6029004Abstract: An apparatus and method reorder portions of a computer program in a way that achieves both enhanced performance and maintainability of the computer program. A global call graph is initially constructed that includes profile data. From the information in the global call graph, an intramodular call graph is generated for each module. Reordering techniques are used to reorder the procedures in each module according to the profile data in each intramodular call graph. An intermodular call graph is generated from the information in the global call graph. Reordering techniques are used to reorder the modules in the computer program. By reordering procedures within modules, then reordering the modules, enhanced performance is achieved without reordering procedures across module boundaries.Type: GrantFiled: March 17, 1997Date of Patent: February 22, 2000Assignee: International Business Machines CorporationInventors: Vita Bortnikov, Bilha Mendelson, Mark Novick, Robert Ralph Roediger, William Jon Schmidt, Inbal Shavit-Lottem

Patent number: 5950009Abstract: An apparatus and several methods provide for a more optimized computer program that will have a faster execution time than was possible using the prior art reordering technique that adds to a trace until it finds no more predecessors or successors to add. The apparatus and methods disclosed herein use a variety of methods to reorder the program portions in a more intelligent manner that will improve its run-time performance. Each of these methods involves constructing traces in the control flow graph of the computer program. In a first embodiment, a basic block is only added to a trace if it is not negligible within predetermined limits. This negligibility test results in traces that are not extended for infrequently executed basic blocks. In a second embodiment, a basic block is only added to a trace if it is a perfect partner with the last basic block added to the trace. The concept of a "perfect partner" helps to match basic blocks together in a trace that have the greatest affinity for each other.Type: GrantFiled: March 10, 1997Date of Patent: September 7, 1999Assignee: International Business Machines CoporationInventors: Vita Bortnikov, Bilha Mendelson, Mark Novick, William Jon Schmidt, Inbal Shavit-Lottem
