Abstract: In various embodiments, techniques for improving function of in-memory processing systems include identifying data stored in a distributed filesystem, including data to be processed by an in-memory processing application and data not to be processed by the in-memory processing application; identifying one or more partitions of the data corresponding to the data to be processed; and selectively transferring the one or more partitions from the distributed filesystem to a memory of the in-memory processing application. Techniques may also include determining an average remote execution time of the in-memory processing system; tracking a waiting time of a job pending processing on a local node of the in-memory processing system; comparing the tracked waiting time of the job pending processing; and demoting a locality of the job if waiting time of the job exceeds the average remote execution time of the in-memory processing system. Corresponding systems and computer-program products are also disclosed.

Abstract: Embodiments relate to dynamically selecting an erasure code. State data is tracked to ascertain frequency of file access. One of at least two erasure codes are selected based on the tracked state data in order to lower data recovery cost. The erasure code may be selected as either a product code or a local reconstruction code. Each erasure code includes a mode that is either a fast code or a compact code. The fast code features a low recovery cost and the compact code features a low storage overhead for less frequently accessed data. Data is encoded with one of the selected erasure codes and one of the modes of the selected erasure code. Data blocks are dynamically converted between the fast and compact codes of the selected erasure code responsive to a workload change.

An example method may include scheduling a first job on a first node, using a first resource manager, establishing a service for a second resource manager on a second node, wherein the service is allocated node resources of the second node, and attempting to schedule a second job on the first node, using the first resource manager. The method may include preempting the service on the second node, using the second resource manager, in response to the attempt to schedule the second job on the first node, and deallocating the node resources of the second node from the service. The method may include advertising, using a node manager of the first resource manager, available node resources of the second node, and scheduling the second job on the second node, using the first resource manager.

Abstract: Schedules are generated that satisfy the objectives of a field services provider given a set of resources and a set of work orders. More particularly, work orders are identified, as well as the identity of resources that are capable with fulfilling one or more of the work orders, are obtained. Feasible paths are established for each resource that identify a sequence of one or more work orders that can be fulfilled by the resource over the course of the resource's work shift and which reflect one or more scheduling objectives. These feasible paths are established in a series of iterations, with each iteration identifying additional paths. After each iteration, it is determined if a pre-selected time limit has been exceeded, and whenever the time limit has been exceeded, path generation ceases. Schedules are established for the resources using the generated paths and are then provided to the field service provider.

Abstract: In one embodiment, a computer-implemented method includes selecting a cache block descriptor (CBD) from amongst a plurality of CBDs stored to a cache storage device to defragment based on a determination of utilization of a particular fine block descriptor (FBD) having a first size that is allocated to the selected CBD. The cache storage device includes a free pool of FBDs having various sizes that is available for use in the plurality of CBDs. Also, the particular FBD having the first size has a lowest availability in the free pool of FBDs. Other methods, systems, and computer program products are described in accordance with additional embodiments.

Abstract: A portable computing device equipped with at least one image capture device and/or a light source captures an image (or a video) of a portion of a surface of interest having the damage that is exposed to a light from the light source. The portable computing device converts the image to an output image that highlights the damage. If the damage is a dent, the image is converted to a false color image using a saliency algorithm. If the damage is a scratch, the image is converted to a colorspace stretched image using color stretching algorithms. The size of the damage is determined by capturing an image of a ruler placed adjacent to the damage and the portion of surface of interest having the damage. The ruler is then removed from the image. The resulting image is converted to the output image. The ruler is added to the output image.

Abstract: Methods and systems for searching logical patterns in voluminous multi sensor data from the industrial internet is provided. The method retrieves instances of patterns in time-series data where patterns are specified logically, using a sequence of symbols. The logical symbols used are a subset of the qualitative abstractions specifically, the concepts of steady, increasing, decreasing. Patterns can include symbol-sequences for multiple sensors, approximate duration as well as slope values for each symbol. To facilitate efficient querying, each sensor time-series is pre-processed into a sequence of logical symbols. Each position in the resulting compressed sequence is registered across a TRIE-based index structure corresponding to the multiple logical patterns it may belong to. Logical multi-sensor patterns are efficiently retrieved and ranked using such a structure. This method of indexing and searching provides an efficient mechanism for exploratory analysis of voluminous multi-sensor data.

Abstract: Techniques are disclosed which allow a secondary storage system to provide data to non-production workloads in conjunction with performing data backup and protection tasks. As disclosed, a secondary storage system exposes backup data stored by the secondary storage system to other workloads, such as test and development applications, data analytics, etc. These non-production workloads can run at the same time the secondary storage system provides backup services to a primary storage system. This consolidation eliminates the need for an enterprise to deploy separate storage clusters for analytics, test and development applications, etc. and eliminates unnecessary copies of data.

Abstract: In a method of loading checked luggage on unit load devices corresponding to an aircraft having a passenger compartment, each piece of checked luggage is associated with a unique identifier. Each piece of checked luggage is weighed and its weight is associated with its corresponding unique identifier. A best possible luggage placement is calculated considering a distribution of passenger weight, thereby allowing the passengers to sit at their preferred location rather than by pre-allocation. A desired placement of the checked luggage is calculated based on the weight of each piece of checked luggage, the acceptable distribution of weight in the passenger compartment and overall fuel state over mission profile.
