Abstract: A plurality of requests are received for computing processing. At least some of the plurality of requests are replicated. The requests are replicated based on a fractional replication factor. Each received request and each replicated request are transmitted to a computer resource for processing. At least some embodiments provide the capability for meeting tail latency targets with improved performance and reduced cost.

Abstract: The present disclosure relates to a method of managing requests to a key-value database. A non-limiting example of the method includes receiving a request that includes a number of keys. The number of keys can be compared with a first threshold number and second threshold number. If the number of keys exceeds the first threshold number, the request can be split. If the number of keys is smaller than the second threshold number, the request can be merged with at least one previous or subsequent request. Requests resulting from the splitting and merging steps can be submitted to the key-value database for further processing of the submitted requests.

Abstract: Embodiments include pre-processing work items to be processed by computerized processing elements. Aspects include accessing a performance index, which relates to (dynamic) processing performances of work items as processed by the computerized processing elements. Aspects also include determining a time interval (during which the receiver may group queued work items into a block, according to the accessed performance index. Aspects further includes setting a timer to the determined time interval, to allow the receiver to group work items being queued until that time interval has elapsed, according to the timer set. As a result, a block of grouped work items will be obtained, which can then be passed to a scheduler for subsequent processing by computerized processing elements.

Abstract: In a process as disclosed according to the present invention, gases or gas mixtures used to form a reactant mixture in an at least temporarily ignitable composition are fed into a mixing chamber (11) through the passages (131) in a boundary wall (13) of the mixing chamber (11) and by means of one or more feed conduits (14) which have feed orifices (141) and extend into the mixing chamber (11), respectively.

Abstract: Embodiments of the invention provide a computer-implemented method for managing cryptographic objects in a key management system. This system comprises a set of one or more hardware security modules (HSMs), as well as clients interacting with the HSMs on behalf of users who interact with the clients. The method comprises monitoring, for each HSM of the set, an entropy pool and/or a load at each HSM. The entropy pool of a HSM is the entropy that is available at this HSM for generating cryptographic objects. The load induced at a HSM is the load due to the users interacting with the clients to obtain cryptographic objects. Cryptographic objects are generated, at each HSM, according to the monitored entropy pool and/or load. The extent to which such objects are generated depends on the monitored entropy pool and/or load.
