Abstract: Systems, apparatuses, and methods for implementing a hierarchical scheduler. In various implementations, a processor includes a global scheduler, and a plurality of independent local schedulers with each of the local schedulers coupled to a plurality of processors. In one implementation, the processor is a graphics processing unit and the processors are computation units. The processor further includes a shared cache that is shared by the plurality of local schedulers. Each of the local schedulers also includes a local cache used by the local scheduler and processors coupled to the local scheduler. To schedule work items for execution, the global scheduler is configured to store one or more work items in the shared cache and convey an indication to a first local scheduler of the plurality of local schedulers which causes the first local scheduler to retrieve the one or more work items from the shared cache.

Abstract: Systems, apparatuses, and methods for implementing a message passing system to schedule work in a computing system. In various implementations, a processor includes a global scheduler, and a plurality of local schedulers with each of the local schedulers coupled to a plurality of processors. The processor further includes a shared cache that is shared by the plurality of local schedulers. Also, a plurality of mailboxes are implemented to enable communication between the local schedulers and the global scheduler. To schedule work items for execution, the global scheduler is configured to store one or more work items in the shared cache and store an indication in a mailbox for a first local scheduler of the plurality of local schedulers. Responsive to detecting the message in the mailbox, the first local scheduler identifies a location of the one or more work items in the shared cache and retrieves them for scheduling locally.

Abstract: A user accesses an intermediary device, in communication with a restricted entity, requires a One Time Credential OTC and activates a mobile device previously registered, by the user, in an authentication entity, in order to generate a OTC, based on the information related to the user, to the restricted entity, to the mobile device and to the authentication entity, the OTC credential being then typed in the intermediary device and transmitted therefrom to the restricted entity and, from the latter, to the authentication entity, in which the OTC credential is decrypted and compared with the information related to the user, to the restricted entity, to the authentication entity and to the mobile device registered in the authentication entity, in order to generate an authentication result which is transmitted to the restricted entity, which will decide to accept or to reject the access of the user.

Abstract: A user (1) accesses an intermediary device (3), in communication with a restricted entity (4), requires a One Time Credential OTC (15) and activates a mobile device (2) previously registered by the user (1) in an authentication entity (5), in order to generate a One Time Credential OTC (15) based on the information related to the user (1), to the restricted entity (4), to the mobile device (2) and to the authentication entity (5), said OTC credential being then typed in the intermediary device (3) and transmitted therefrom to the restricted entity (4), and from the latter to the authentication entity (5), in which the -OTC credential is decrypted and compared with the information related to the user (1), to the restricted entity (4), to the authentication entity (5) and to the mobile device (2) registered in the authentication entity (5), in order to generate an authentication result (47) which is transmitted to the restricted entity (4), which will decide to accept or to reject the access of the user (1).

Abstract: A handheld power tool is disclosed. The handheld power tool has a drive oscillating along a working axis and a vibration damper. The vibration damper has a mass element suspended in a spring mechanism. The spring mechanism acts with a first spring stiffness and acts with a second spring stiffness. The first spring stiffness is different from the second spring stiffness.

Abstract: A user submits an unstructured query that is analyzed to determine a mapping from attributes to attribute values. One or more matching items from a structured data set are determined based on the attribute values of attributes associated with the items. The matching items are displayed. One or more refinement attributes are displayed, each with one or more attribute values. The attribute values in the refinements that correspond to the attribute values of the query are shown as selected. If the user selects any of the refinement attributes, the query is revised to incorporate the attribute values of the selected refinements. New matching items are determined using the revised structured query. The revised structured query and the new matching items are displayed. This process can be iterated, by modification of the query or the refinements. The matching items, the selected refinement attribute values and the query are synchronized.
