Abstract: A method and computer program product for testing a high performance computing application performing a computation within a clustered computer arrangement is disclosed. The high performance computing arrangement performances computations across processors in parallel wherein the processors cooperate to perform the computation. The application can be tested by adding delay and therefore latency to one or more commands inside of the precompiled application. The addition of delay can be used to simulate the performance of different interconnects that are used within the high performance computing arrangement.

Abstract: In accordance with some implementations, a method for evaluating large scale computer systems based on performance is disclosed. A large scale, distributed memory computer system receives topology data, wherein the topology data describes the connections between the plurality of switches and lists the nodes associated with each switch. Based on the received topology data, the system performs a data transfer test for each of the pair of switches. The test includes transferring data between a plurality of nodes and determining a respective overall test result value reflecting overall performance of a respective pair of switches for a plurality of component tests. The system determines that the pair of switches meets minimum performance standards by comparing the overall test result value against an acceptable test value. If the overall test result value does not meet the minimum performance standards, the system reports the respective pair of switches as underperforming.

The temporal data may be processed for a hardware device for a defined time period to develop one or more temporal performance metrics. Additionally, all activities that occur on a hardware device for a given time period can be determined and visualized.

Abstract: An electronic handheld device with remote cable release mechanism, a handle portion and method for performing the same. The device includes a housing defining an internal cavity and has an elastically deformable flexible portion. An electrical connector block is disposed in the cavity and includes a female receptacle configured for receiving a male electrical cable connector having a movable locking clip configured to releasably engage the connector block. An actuating protrusion is preferably disposed on the flexible portion of the housing for releasing the cable connector. The protrusion is movable towards the connector block in response to the application of an inward pressing force on the flexible portion. The protrusion operates to depress the locking clip on the cable connector, thereby releasing the cable connector. In another embodiment, a resealable dimple may be provided in the flexible portion which can be punctured via a probe to access the locking clip.

Abstract: An image without use of a flash is taken, along with an image using a flash. A difference image is generated by subtracting the flash-less image from the flash image. A threshold is applied to the difference image such that only large differences in intensity remain in the difference image. This artifact image is then subtracted from the flash image, thereby removing flash artifacts such as specular reflections and red-eye. The threshold used may be automatically calculated or may be set by the user. For some applications it may be desirable to set separate thresholds for each dimension of the color space (such as red, green, and blue) used. Once again these separate thresholds may be automatically calculated or may be set by the user.
