Abstract: A method, computer program product, and system identify a low-cost time to re-boot a system. The method includes a processor obtaining a request for a re-boot of a system. The processor obtains identifiers of uncompleted tasks executing in the system. Based on obtaining the identifiers, the processor obtains a task cost of each task of the uncompleted tasks, where a value of the task cost of each task relates to a portion of each task completed by the processor at a given time. The processor determines, based on the task costs associated with the uncompleted tasks, a re-boot cost for re-booting the system at the given time. The processor determined a system cost for not re-booting the system at the given time. The processor compares the re-boot cost to the system cost to determine whether to re-boot the system at the given time in response to the request.

Abstract: Methods, computer program products and computer systems for optimizing client distances to nodes in a distributed computing environment are provided. A first registration request is received by a first node from a first client. The first node determines if a second client associated with the first node is suitable for an exchange to a second node. The first node sends a migration request to the second client responsive to determining the second client is suitable. The first node accepts the first registration request responsive to the second client connecting to the second node via a second registration request.

Abstract: Provided are a computer program, method, and system for determining and assigning a default value to a current server response if the current server response is not received from the server within a time-limit. An indication of a submission of a request is transmitted to the server for receiving a current server response. A default value is assigned to the current server response if the current server response is not received from the server within a time-limit with respect to the current submission of the request. A set of operations being performed from the assignment of the default value to the current server response is logged. An actual value of the current server response is received from the server and the logged operations are rolled-back and the current server response reset to the actual value if the actual value is different from the default value.

Abstract: Embodiments of the present disclosure relate to improving computer performance. An action may be issued to a first client and a second client. A first optimization factor list (OFL) may be generated for the first client and a second OFL may be generated for the second client. After each OFL is generated, the first OFL may be compared to the second OFL. A correlation factor (CF) may be generated between the first client and the second client based on the OFL comparison, wherein the CF indicates a level of similarity between the first client and the second client. A bottleneck causing performance issues in the first client may be determined and computer configuration of the first client may be adjusted based on the bottleneck.

Abstract: In an approach for visually enhancing tactile metadata, a computer receives an image on a first computing device. The computer selects an object from one or more objects depicted within the received image. The computer determines boundaries of the selected object. The computer assigns an object tag to the selected object within the determined boundaries, wherein the assigned object tag includes one or more keywords and terms describing the selected object. The computer assigns tactile metadata to the selected object within the determined boundaries based on one or more physical properties associated with the assigned object tag. The computer creates a visually enhanced image based on the assigned tactile metadata, wherein the assigned tactile metadata includes one or more physical properties associated with the assigned object tag capable of being represented visually.

A future requirement of the computing resources for the software application is then forecasted according to the monitored social information and the estimated correlation for use in provisioning the computing resources to the software application accordingly.

Abstract: Techniques are disclosed for validating a ticket based on biometric data provided by a ticket holding user. A ticket controller device broadcasts an inquiry frame specifying a request for authentication data for a ticket user requesting access to a service hosted by the ticket controller. A mobile device may receive the inquiry frame and generate a response frame encapsulating a ticket identifier and biometric data associated with a user. The ticket controller receives the response frame including the ticket identifier and the biometric data. Upon determining that the ticket identifier and the biometric data encapsulated in the response frame matches a stored ticket identifier and biometric data, the ticket controller grants the user access to the service.
