  • Patent number: 11221884
    Abstract: According to one aspect of the present disclosure, a method and technique for hybrid virtual machine configuration management is disclosed. The method includes assigning to a first set of virtual resources associated with a virtual machine a first priority and assigning to a second set of virtual resources associated with the virtual machine a second priority lower than the first priority. An operating system of the virtual machine is provided with the first and second priorities assigned to the respective first and second sets of virtual resources. The operating system dispatches to process a workload the virtual resources from the first set before dispatching the virtual resources from the second set.

  • Patent number: 10310860
    Abstract: A system and method adjust instruction dispatch in a multi-pipeline processor core having a plurality of execution units for improved performance of out-of-order execution of instructions. A dispatch adjust circuit receives a queue full signal from one or more of the execution queues that indicates the corresponding execution queue is full. In response to the queue full signal, the instruction dispatch circuit sends a stop signal to the instruction issuer to stop issuing additional instructions to the queues until one or more of the queues are empty. The dispatch adjust circuit may also receive a queue empty signal from the queues to detect when they are empty to send a start signal to the issuer.

  • Patent number: 9563559
    Abstract: Some embodiments of the inventive subject matter are directed to operations that include determining that an access request to a computer memory results in a cache miss. In some examples, the operations further include determining an amount of cache resources used to service additional cache misses that occurred within a period prior to the cache miss. Furthermore, in some examples, the operations further include servicing the access request to the computer memory based, at least in part, on the amount of the cache resources used to service the additional cache misses within the period prior to the cache miss.

  • Patent number: 9513952
    Abstract: A mechanism is provided for sharing resources allocated to an entitled virtual machine (VM). A blocked domain is created around the entitled VM and one or more processors allocated to the entitled VM. A first dispatching algorithm is implemented that prevents the dispatching of processes from other operating systems within other VMs to the one or more processors allocated to the entitled VM. Responsive to utilization of the one or more processors allocated to the entitled VM falling below a predetermined threshold, a second dispatching algorithm is implemented that allows dispatching of processes from the other operating systems within the other VMs to the one or more processors allocated to the entitled VM.

  • Patent number: 9086888
    Abstract: A method for processing instructions. The instructions are processed by a processor unit while using a first table in a plurality of tables to predict a set of instructions needed by the processor unit after processing of a conditional instruction. An identification is formed that a rate of success in correctly predicting the set of instructions when using the first table is less than a threshold number. A sequence of the instructions being processed by the processor unit is searched for an instruction that matches a marker in a set of markers for identifying when to use the plurality of tables. An identification that the instruction that matches the marker is formed. A second table from the plurality of tables referenced by the marker is identified. The second table is used in place of the first table.
