Appl. No.:

12/819069

Inventors:

John Erickson - Redmond WA, US
Madan Musuvathi - Redmond WA, US

Assignee:

MICROSOFT CORPORATION - Redmond WA

International Classification:

G06F 11/26
G06F 12/00

US Classification:

714 37, 714E11159, 714 42, 711147, 711E12001

Abstract:

Described are techniques for detecting data collisions between a first portion and a second portion of an application executing on a computer, the first portion and the second portions executing concurrently with respect to each other. While the first portion and second portion are executing, before the first portion accesses a memory location shared by the first portion and the second portion, a value stored in the memory location is captured and the first portion is delayed. While the second portion continues to execute the first portion is delayed. After a period of the first portion having been paused or slowed, the current content of the memory location is compared with the captured content to determine if there is a data collision. The first and second portions may be threads, and the capturing, delaying, and determining may be performed by code inserted to the application after it has been compiled.

Assignee:

Microsoft Corporation - Redmond WA

International Classification:

G06F 11/07

US Classification:

714 35, 714E11029

Abstract:

The claimed subject matter provides a method for detecting a data race. The method includes inserting a plurality of breakpoints into a corresponding plurality of program locations. Each of the program locations accesses a plurality of memory locations. Each of the program locations is selected randomly. The method also includes detecting one or more data races for the memory locations in response to one or more of the breakpoints firing. Additionally, the method includes generating a report describing the one or more data races.

Appl. No.:

6/712219

Inventors:

John S. Erickson - Everett WA

International Classification:

A63C 1122

US Classification:

280824

Abstract:

Ski pole modifying apparatus includes a seat contacting member and a ski/boot contacting member. The seat contacting member includes a pole encircling portion with an elongated collar section. An arm portion extends from the collar section and includes a transverse section extending the full length of the arm portion disposed in a plane substantially perpendicular to an axis of the collar section. A radial section extends from the periphery of the collar section along substantially the full height thereof and tapers downwardly toward the free end of the transverse section. The ski/boot contacting member includes a platform portion with a central opening surrounded by a cylindrical section and an odd number of substantially equal length peripheral edges with a minimum of five. A generally circular opening extends through the platform portion adjacent a midpoint of each peripheral edge thereof. Each circular opening includes a channel communicating with the adjacent peripheral edge with the channel having a width less than the diameter of the circular opening.

Inventors:

John S. Erickson - Everett WA

International Classification:

A63C 1122

US Classification:

280819

Abstract:

Ski pole modifying apparatus including a support portion, a hanger portion, a pivoting portion and a stabilizer portion; the support portion including an elongated main section, the main section being capable of mounting on a ski pole intermediate the ends thereof; the hanger portion extending from the support portion, the hanger portion including an arm member with a free end, the arm member being capable of extending generally perpendicularly from the main section; the pivoting portion including mechanism for changing the position of the hanger portion about a transverse axis through the ski pole from a position in which the free end of the arm member of the hanger portion is remote from the ski pole to a position in which the free end is disposed adjacent to the ski pole; the stabilizer portion retaining the position of the hanger portion with respect to the ski pole; whereby when the modifying apparatus is mounted on a ski pole, the hanger portion can be pivoted to a position so it can lay on a ski lift seat to enable a skier to rest his feet on ski pole baskets.

International Classification:

G06F 9/44
G06F 12/0897

Abstract:

Technologies that allow for a significant reduction in the time required to incrementally build large computer programs, and increase in the scale of build systems that perform builds. The time reduction is caused by reducing the time required for processing systems in a distributed build system to acquire files needed for the respective processing system to perform their respective part of the build. The scale increase comes from relying on local processing systems instead of centralized processing systems. This is done by establishing a tier of cache locations on which appropriate files for a build may be found by the appropriate processing system. A system may be established that allows for the processor systems to validate that the files have not been tampered with by using signatures, and were appropriately identified.

International Classification:

G06F 17/30
G06F 9/45
G06F 9/44

Abstract:

Deduplication is integrated with software building and chunk storing. A dedup module includes dedup software, a build graph interface, and a chunk store interface. A dedup graph includes a portion of the build graph, and a portion that represents build artifact file chunks. The dedup software queries whether chunks are present in the chunk store, submits a chunk for storage when the chunk is not already present, and avoids submitting the chunk when it is present. Queries may use hash comparisons, a hash tree dedup graph, chunk expiration dates, content addressable chunk store memory, inference of a child node's presence, recursion, and a local cache of node hashes and node expiration dates, for example. A change caused by the build impacts fewer dedup graph nodes than directory graph nodes, resulting in fewer storage operations to update the chunk storage with new or changed build artifacts.

US Classification:

370352

Abstract:

An IP telephony system allows a user to register a telephony device that receives its native telephony service from a different telephony service provider as an extension telephone. The user can then place calls through the IP telephony system using the extension telephone. Such calls may or may not be established using the extension telephone's native telephony service provider.
