Abstract: In at least one embodiment of stream processing in a data processing system cluster, a driver requests, from a cluster manager, execution of a first task within a job including a plurality of tasks, as well as a first quantity of resources of the cluster to support execution of the task. At completion of execution of the first task by the cluster, the driver retains for a second task among the plurality of tasks at least a portion of the resources allocated to the first task by the cluster manager. The driver determines a second quantity of the resources to retain for the second task based on a relative priority of the job to other jobs in the cluster and efficiency of the cluster manager in allocating resources to the first task.

Abstract: A job in a high performance computing system is executed according to a current scheduler configuration. The job is monitored to determine the job's actual resource usage, the job's performance metric and the job's completion. Responsive to determining that the job completed executing, a difference is computed between allocated resources allocated according to the current scheduler configuration at job submission for execution on the high performance computing system and the job's actual resource usage at the job's completion, wherein the difference is computed for each of N number of jobs that complete executing on the high performance computing system, wherein all of the N number of jobs are associated with a given user. Responsive to determining that the difference for said each of N number of jobs meets a criterion, the current scheduler configuration is automatically reconfigured to reduce the allocated resources for the jobs associated with the given user.

Abstract: The present invention extends to methods, systems, and computer program products for optimizing selection of battery electric vehicles to perform delivery tasks. Within a group of battery electric vehicles (“BEVs”), a BEV is selected to perform a delivery task based on battery charge status. The BEV can be selected based on one or more of: proximity to a requested pick up location, battery state-of-charge (“SOC”), charging station proximity to a requested delivery location, and charging station port availability (e.g., wait time to access a charging port). BEV selection can be optimized such that a BEV arrives at a charging station with optimal remaining SOC. Thus, the distance to charging stations can be optimized while meeting the needs of customer requests to get a delivery from a pickup location to delivery location. In some aspects, autonomous vehicle technology is used to operate BEV's.

Abstract: A technique for managing pooled resources in a distributed computing environment includes a resource manager executable to receive resource allocation requests from a plurality of workload managers for running one or more applications. The applications are initiated by a consumer through the workload managers. Each workload manager is configured to translate demand requests from the applications into resource allocation requests. A determination is made whether there are available resources to satisfy the resource requests according to a resource allocation policy. Resources are allocated to the workload managers where the applications can continue running on the allocated resources if the resource manager suffers downtime or is taken offline. The resource allocation policy is determined by a consumer profile of the consumer specifying ownership and share rights to the requested resources.

Abstract: A resource manager for managing the sharing of resources among multiple workloads in a distributed computing environment. The resource manager comprises an allocation service component which applies a resource allocation policy to determine whether the requested resources may be allocated. The resource manager also comprises a dynamic provisioning service component which applies a reprovisioning policy to modify the make-up of the resources in response to unsatisfied resource requests. The allocation of resources to consumers may be determined in accordance with the resource ownership and share rights of the consumer on behalf of which the application or workload is being demanded.

Abstract: NBT-PVA film dosimeters performance is affected due to high humidity levels. NBT-PVB film dosimeters with a relatively small effect of high humidity levels on its performance are invented. NBT-PVB film dosimeters are made by using alcoholic solution to dissolve both of NBT and PVB. The films are very useful for routine dosimeter in industrial radiation processing. A very high sensitivity NBT-PVB Radio-chromic film dosimeter is achieved due to high solubility of NBT dye in 2-methoxyethanol enabling the addition of very high concentrations of NBT dye in the film dosimeters. The dose response of conventional NBT-PVA dosimeter films are normally saturated after 50 kGy, while the invented composites of NBT-PVB dosimeter films demonstrated high dose range up to 100 kGy for high dose industrial use.

Abstract: A device receives a request from an Internet Protocol (IP)-based device to create a virtual extension of a plain old telephone service (POTS)-based telephone line, authenticates the IP-based device for association with the POTS-based telephone line, and creates the virtual extension of the POTS-based telephone line to the IP-based device when the IP-based device is authenticated.

Abstract: A service controller for providing centralized service management, control and placement, as well as guaranteed failover, in a dynamic and distributed computing environment. The service controller works in conjunction with a computing resource supply manager, which supplies the required resources so that the service controller can run the service on the allocated resources. The number of active service instances may dynamically increase or decrease in accordance with changing availability of or demand for resources. The service controller monitors the service instances and takes appropriate action in the event of service instance failures. The service controller is provided with a service director component, which records and tracks, for each service instance which has been started on a particular resource/host, the IP address of such host, through a name location service, thus allowing end-users to locate the service regardless of where the service instances are physically running.

Abstract: A tetrazolium bromide dye, e.g., 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT), to be used as a high dose solution dosimeter is disclosed. The dose response of MTT solution dosimeter increases strongly with increase of absorbed dose up to 1 kGy. In order to increase the dose range and for ease of handling the present dosimeter as routine dosimeter, MTT-polyvinyl alcohol (PVA) film dosimeter is used. The dose response of MTT-PVA film dosimeters increases strongly with increase of absorbed dose up to 25 kGy. Polyvinyl butyral (PVB) as a polymer for making a film provides more stability at higher temperatures and humidity levels and less calibration is required. The dose response of MTT-PVB film dosimeters is effective with absorbed dose of up to 100 kGy.
