Abstract: Methods and systems are provided for analyzing parallelism of program code. According to a method, the sequential execution of the program code is simulated so as to trace the execution procedure of the program code, and parallelism of the program code is analyzed based on the result of the trace to the execution procedure of the program code. Execution information of the program code is collected by simulating the sequential execution of the program code, and parallelism of the program code is analyzed based on the collected execution information, so as to allow programmers to perform parallel task partitioning of the program code with respect to a multi-core architecture more effectively, thus increasing the efficiency of parallel software development.

Abstract: An information handling system (IHS) may include a processor with multiple compute elements that decode pictures from an encoded video bitstream. Each compute element may perform a different part or sequential stage of a picture decoding process to obtain decoded pictures. A memory includes a decoded picture buffer that associates with a first stage of the sequential stages. The memory may also include respective decoded picture buffer snapshots for sequential stages other than the first sequential stage. A last sequential stage provides fully decoded pictures to a decoded picture pool in memory. The decoded picture buffer and decoded picture buffer snapshots may store pointers to decoded pictures in the decoded picture pool that the sequential stages need to perform decoding of pictures. In this manner, the sequential stages may share decoded pictures that the decoded picture pool stores.

Abstract: A social networking system presents content items to users, who then provide feedback regarding pairs of content items. The feedback includes a selection of a content item of the pair of content items that was preferred by the user over the other content item. The social networking system uses this information to train a predictive model that scores content items based on quality. The content items may be advertisements. The social networking system uses the pair-wise comparisons of the advertisements to determine feedback coefficients in an advertising quality score prediction model using regression analysis of the pair-wise comparisons for each predictive factor in the model. In this way, the pair-wise comparisons are used to train the prediction model to understand which advertisements are more enjoyable than others. A feedback coefficient for each predictive factor may be computed based on the preferences received from the group of users.

Abstract: A cross descriptor learning system, method and program product therefor. The system extracts descriptors from unlabeled exemplars. For each unlabeled exemplar, a cross predictor uses each descriptor to generate labels for other descriptor. An automatic label generator also generates labels for the same unlabeled exemplars or, optionally, for labeled exemplars. A label predictor results for each descriptor by combining labels from the cross predictor with labels from the automatic label generator.

Abstract: Techniques are disclosed for detecting new events in a video stream that yield improved detection efficiency in real time. For example, a method determines whether a given event is a new event in a video stream. The video stream includes a plurality of events. A first step extracts a first set of features (e.g., text features) from the given event. The first set of features is computationally less expensive to process as compared to a second set of features (e.g., image features) associated with the given event. A second step computes one or more first dissimilarity values between the given event and one or more previous events in the video stream using only the first set of features when one or more first dissimilarity criteria exist. A third step determines whether the given event is a new event based on the one or more computed first dissimilarity values.
