Abstract: A method, system, and computer program product for resolving cache lookup of large pages with variable granularity are provided in the illustrative embodiments. A number of unused bits in an available number of bits is identified. The available number of bits is configured to address a page of data in memory, wherein the page exceeding a threshold size, and the page comprising a set of parts. The unused bits are mapped to the plurality of parts such that a value of the unused bits corresponds to existence of a subset of the set of parts in a memory. A virtual address is translated to a physical address of a requested part in the set of parts. A determination is made, using the unused bits, whether the requested part exists in the memory.

Abstract: Approaches presented herein enable performing a health analysis of a user using a smart floor mat. Specifically, a sensory array of the smart floor mat collects static and dynamic pressure data for capturing the movement and force exerted by a user's feet as the user walks across the smart floor mat. A healthcare analysis is then performed by comparing this current measurement data against the user's historical measurement data and expected results to generate a healthcare insight such as a trend, pattern, or deviation. The healthcare insight can predict or indicate a health issue. If a deviation exceeding a predefined permissible threshold exists, a healthcare professional can be notified.

Abstract: Multi-processor computing device methods manage resource accesses by a signaling event manager signaling processor elements requesting access to a resource to wake up to access the resource when the resource is available or wait for an event when the resource is busy. Processor elements may enter a sleep state while awaiting access to the requested resource. When multiple elements are waiting for the resource, the processor element with a highest assigned priority is signaled to wake up when the resource is available without waking other elements. Priorities may be assigned to processor elements waiting for the resource based on a heuristic or parameter that may depend on a state of the computing device or the processor elements. A sleep duration may be estimated for a processor element waiting for a resource and the processor element may be removed from a scheduling queue or assigned another thread during the sleep duration.

Abstract: For location-based communication with mobile devices, a condition is received, at a device associated with a caller, where the condition has to be satisfied by a callee at a past location, the past location being a place where different callees with different mobile devices are present at different times. At the device associated with the caller, an instruction is received for making a telecommunication call to a mobile device of a potential callee in a set of potential callees, where each mobile device associated with each potential callee in set of potential callees was present at the past location at a past time, and where each potential callee in the set of potential callees satisfies the condition at the past location. Using a processor and a memory in the device associated with the caller, the telecommunication call is initiated to mobile devices associated with a subset of potential callees.

Abstract: For location-based communication with mobile devices, a condition is received at a device associated with a caller. The condition has to be satisfied by a callee at a future time and at a location, the location being a place where different callees with different mobile devices are present at different times. An instruction is received at the device for making a telecommunication call to the location where the callee is present with a mobile device and satisfies the condition at the future time. A set of potential callees is identified. Each mobile device associated with each callee in set of potential callees is present at the location at the future time, and each potential callee in the set of potential callees satisfies the condition. The telecommunication call is initiated to mobile devices associated with a subset of potential callees, the subset of potential callees including the callee.

Abstract: For current location-based telecommunication, an instruction is sent from a caller communication device to initiate a telecommunication with a set of destination communication devices. The instruction includes identifying information for a reference device but does not include any identifying information for the set of destination communication devices. Telecommunication data is received at the caller communication device from a destination communication device in the set of destination communication devices, where a server has established a communication channel between the caller communication device and the destination communication device based on a geolocation proximity of the destination communication devices relative to the reference device.

Abstract: In an approach to cooperative evidence gathering, a first computing device receives a request for data corresponding to an event, where a second computing device detecting the event initiates the request for data. The first computing device aggregates data from one or more sensors, the one or more sensors associated with one or more first computing devices within a proximity of a location of the event. The first computing device determines whether at least a portion of the aggregated data is applicable to the event.

Abstract: For location-based communication with mobile devices, a set of callee conditions is received at a caller's device, which has to be satisfied by a callee according to information descriptive of a condition of the callee. The state information is distinct from the location and a time of the callee's presence at the location. An evaluation is made that each device associated with each potential callee in a first subset has been present at the location at a specified time, and that each potential callee in the first subset satisfies the set of callee conditions. At the caller's device, an instruction is received for making a telecommunication call to a device of a potential callee in a first subset. The call is initiated from the caller's device to mobile devices associated with the first subset of potential callees.

Abstract: A request to access to a logical location in a file stored in a content addressable storage (CAS) system can be handled by retrieving first tree data from a first node in a hash tree that represents the file, the first tree data including a first hash tree depth, a first CAS signature, a block size and a file size. Based on the tree data, a second node is selected from a higher level in the hash tree. Second tree data from the second node of the hash tree that represents the file is retrieved, including a second CAS signature. The second CAS signature is determined to match a reserved CAS signature, and in response, an indication that the requested logical location is unallocated within the file is provided.

Abstract: A request to access to a logical location in a file stored in a content addressable storage (CAS) system can be processed by retrieving first tree data from a first node in a first hash tree that represents a first version of the file. Based on the first tree data, a second node is selected from which a CAS signature is compared to a reserved CAS signature to determine the proper file version. In response to a match, a third node is accessed in a second hash tree that represents a second version of the file. Tree data is retrieved from a third node.

Abstract: A method, system and computer program product for assisting a user to meet with other users with complementary attributes. Attributes (e.g., likes, dislikes) of a user, such as a user of a mobile device, are received to populate a profile of the user. The user attributes of profiles of actively participating users that are located in a geographic area are analyzed with respect to the attributes of the user to identify other users with complementary profiles. Those users with complementary profiles as the user are clustered to form a “cluster” at a designated waypoint. Directions are then provided to the user to reach the designated waypoint to meet the other users of the same cluster. In this manner, the user is able to meet other users in the physical world with complementary interests and experiences at a designated waypoint.

Abstract: An instruction for making a call to a location is received at an application executing in a service provider system. The location is a place where different callees with different mobile devices are present at different times, and a callee is present with a mobile device at the place at a given time therefore the call is made to the mobile device of the callee in order to call the location. Using the application, a set of locations corresponding to a set of subscribers is detected. From the set of subscribers, a set of potential callees is identified. Each mobile device associated with each callee in the set of potential callees is present at the location at the given time. Using the application, the call is established between a caller's device and the mobile devices of a subset of potential callees, the subset of potential callees including the callee.
