Methods, systems, and apparatus, including computer programs encoded on computer storage media, for distributing a top k computation across multiple computing units of an integrated circuit One of the methods includes computing, by each of the plurality of computing units and for each candidate vector in a respective subset of the candidate vectors assigned to the computing unit, a respective distance between the query vector and the candidate vector; initializing, by the integrated circuit, a cut-off distance value; determining, by the integrated circuit, a final cut-off distance value; and providing, by the integrated circuit and as an output of a top k computation for the query vector and the set of candidate vectors, the candidate vectors that have respective distances that satisfy the final cut-off distance value.

Methods, systems, and computer-readable media for analysis of code coverage differences across environments are disclosed. A code coverage profiling system determines a first code coverage profile associated with execution of program code in a first environment. The first code coverage profile indicates one or more portions of the program code that were executed in the first environment. The code coverage profiling system determines a second code coverage profile associated with execution of the program code in a second environment. The second code coverage profile indicates one or more portions of the program code that were executed in the second environment. The code coverage profiling system performs a comparison of the first code coverage profile and the second code coverage profile. The comparison determines a difference between the portions of the program code that were executed in the first and second environments.

Source code of a golden version and a next version of a program is received in which procedure calls are modified to call from an entry point table (EPT) with index numbers corresponding to procedure memory addresses. An executable defect-free golden version program and next version program with a defect are received. A first entry point table (first EPT) for the new version program and a second EPT for the golden version program are generated. A series of substitutions of procedures from the second EPT to the first EPT is performed and an order of substitutions includes: a module set, a module of the module set, a procedure set of the module, and a procedure of the procedure set. The defect producing procedure is identified by substituting in order until the defect is absent and proceeding to the next substitution in order.

Embodiments include methods, and adaptive testing systems, and computer program products for performing adaptive testing using one or more system resources of a computer system dynamically determined from a platform on which a test program is executing. Aspects include: test program sending a resource query based on certain criteria to a resource query module to inquire one or more available system resources of computer system, the resource query module using certain operating system commands of computer system to determine appropriate system resources available for use on the computer system, the computer system returning the appropriate system resources determined on the computer system to the resource query module of the test program, the test program deciding one or more system resources that best meet a need of the test program, and the test program performing the adaptive testing on the computer system based on the one or more system resources decided.

The systems and methods that determine tests that may be executed in parallel during regression testing of an analytics application are provided. Multiple tests that test functions of the analytics application are accessed from a test automation suite. For each test, data sources that provide data to the analytics application during the test are identified. The tests are aggregated into temporary groups according to the identified data sources. The test groups are generated from the temporary groups such that each test group comprises tests that are associated with non-overlapping data sources. The regression testing is performed on the application by executing the test groups in parallel.

Software code is tested to determine relative performance of the software code. Successfully executing a test may be used to flag problems in a code repository to be corrected or criteria for accepting code for acceptance to the repository. To further evaluate test results, the test may be run several times on the same code version to determine a test result stability score describing how the test results may vary in different executions, such as a frequency that the code passes the test. Based on the score, additional tests may be run to further refine test result stability score. To evaluate time-variance of testing, when a code version fails a test, a previous version of the code may be run with the same test and the results compared to determine if a new regression was introduced.

A relay and metering test instrument includes an application processor circuitry to control functional operation of the relay and metering test instrument. The application processor circuitry may receive a user selected source code state program, and operational parameters input by the user. The application processor circuitry may compile the source code state program and the operational parameters into a test routine for storage in a memory circuitry with other test routines. The relay and metering instrument may also include a real time processor circuitry and an input/output processor circuitry. The real time processor circuitry may selectively and independently execute the test routine or one of the other test routines to perform one or more respective testing stages. The input/output processor circuitry may cooperatively operate with the real time processor circuitry to output test signals and monitor for receipt of input test signals according to execution of the test routine.

A system may include an active first point of deployment (POD) configured to provide a specified business functionality and may include a first server and a first instance of a platform to provide the specified business function. A dark second POD may be configured to include a second server and a second instance of the platform template, where the first platform template instance comprises a different version than the second platform template instance. A POD management computing device may test an operation of the second POD in parallel with the operation of the first POD. The POD management computing device may upgrade the business functionality by deactivating the first POD and activating the second POD to provide the specified business function using the second instance of the platform template.

In at least one embodiment, a system and method described herein provides a concrete and tangible solution to solve a problem of remotely and programmatically activating and manipulating a device to capture screen shots of a complete web page and, in at least one embodiment, prevent and, if necessary, recover from device crashes.

A method includes asserting a field of an event flag mask register configured to inhibit an event handler. The method also includes, responsive to an event that corresponds to the field of the event flag mask register being triggered: asserting a field of an event flag register associated with the event; and based the field in the event flag register being asserted, taking an action by a task being executed by the data processor core.
