摘要： A multiprocessor computing system includes a direct memory access (DMA) engine, a main memory and a host processor including a just-in-time compiler (JIT) that converts bytecode into machine code in discrete executable superblocks (XSBs). The system also includes a system bus coupled to the host processor, the DMA engine and the main memory and allowing communication there between and an auxiliary processing unit (APU) coupled to the system bus and having a local memory, the APU receiving a first XSB from the JIT and storing it in the local memory and loading the one or more next XSBs for execution found in the header of the first XSB into the local memory via the DMA engine.

摘要： A method and computer system are provided for distributing a plurality of data portions from a server system to one or more client systems. The method includes receiving one or more first requests at the server, each first request being submitted by a client system and including a portion identifier, wherein a portion identifier is assigned to each data portion; in response to receiving the first request(s), transmitting a list of chunk identifiers to the requesting client systems, wherein the list of chunk identifiers specifies the data chunks whose meta-data includes the portion identifier contained in the first request; and transmitting some or all data chunks of a data chunk library to each of the requesting client systems. At the requesting client system, the client specifically selects the data chunks of the transmitted data chunks which are specified by the received list of chunk identifiers.

摘要： Aspects of the invention provide a solution for determining a storage location for a data item from among a set of persistent storage locations having varying access speeds. Each data item is associated with a score that is based on the frequency with which the data item has been accessed, as well as possible other factors such as open time and/or close time of the data item, the amount of data in the data item, the period from the last time the data item was closed to the next time that the data item is opened and/or the total amount of data in the data item. Data items with high scores relative to other data items are assigned to faster access storage location while data items with lower scores are assigned to slower access storage locations.

摘要： Efficiently determining identical pieces of memory within a computer memory area, which is occupied by a virtual machine manager hosting multiple guests and the computer memory area being logically separated into memory pages of a unique size. Each guest is inspected for its structural characteristics by the virtual machine manager. The structural characteristics of each guest are compared by the virtual machine manager, wherein memory regions of guests having a similar structure are identified; and the identical memory pages are identified by the virtual machine manager by comparing hash values of memory pages located within memory regions of guests having a similar structure, wherein identical memory pages are determined by comparing hash values calculated over the contents of the memory pages.

摘要： A system and associated method for shifting workloads across platform in a hybrid system. A first kernel governing a first platform of the hybrid system starts a process that is executable in a second platform of the hybrid system. The first kernel requests a second kernel governing the second platform to create a duplicate process of the process such that the process is executed in the second platform. The process represents the duplicate process in the first platform without consuming clock cycles of the first platform. During an execution of the duplicate process in the second platform, the first kernel services an I/O request of the duplicate process that is transferred from the second kernel to the first kernel. When the duplicate process is terminated, the process in the first platform is removed first before the duplicate process releases resources.
