摘要： A system, method and computer program product for allocating shared resources. Upon receiving requests for resources, the cost of bundling software in a virtual machine (VM) image is automatically generated. Software is selected by the cost for each bundle according to the time required to install it where required, offset by the time to uninstall it where not required. A number of VM images having the highest software bundle value (i.e., highest cost bundled) is selected and stored, e.g., in a machine image store. With subsequent requests for resources, VMs may be instantiated from one or more stored VM images and, further, stored images may be updated selectively updated with new images.

摘要： A template generator organizing templates in a cost-aware clustering, a method of allocating resources using cost-aware clustering and computer program products therefor. A resource provisioning unit generates, selects and maintains a selected number of resource templates. Each template specifies an allocable resource capacity configuration. Each requesting client device has resources allocated determined by one of the selected resource templates. A resource provisioning unit includes a configuration store with costs of allocable resources and associated attributes, a server request store with previously received requests, and an input parameter store with template list options. A template generator determines an optimum list of templates to satisfy previously received requests. A template store stores generated template lists.

摘要： Aspects of the present invention provide a tool for analyzing and remediating an update-related failure. In an embodiment, a failure state of a computer system that has been arrived at as a result of an update is captured. A semantic diff that includes the difference between the failure state and at least one of an original state or a completion state is then computed. This semantic diff is transformed into a feature vector format. Then the transformed semantic diff is analyzed to determine a remediation for the update. Failure and/or resolution signatures can be constructed using the semantic diff and contextual data, and these signatures can be used in comparison and analysis of failures and resolutions.

摘要： Aspects of the present invention provide a solution for passively monitoring a computer system. In an embodiment, a virtual server is accessed by an indexing agent that is contained in an indexing appliance. The virtual server is located on a physical server and is one of a plurality of virtual system instances on a common physical server. The indexing appliance is separate from the virtual server and, as such, the indexing agent is not executed within the virtual server, itself. The indexing agent retrieves a virtual image of the virtual server and indexes the virtual image to extract features indicative of changes in the virtual server. These features are analyzed to perform passive monitoring of the virtual server. Since the indexing appliance is separate from the virtual server for which passive monitoring is being performed, the indexing agent can perform the retrieving and the indexing without utilizing agents executing within the virtual server.

摘要： Systems and methods are disclosed that allow atomic updates to global data to be at least partially eliminated to reduce synchronization overhead in parallel computing. A compiler analyzes the data to be processed to selectively permit unsynchronized data transfer for at least one type of data. A programmer may provide a hint to expressly identify the type of data that are candidates for unsynchronized data transfer. In one embodiment, the synchronization overhead is reducible by generating an application program that selectively substitutes codes for unsynchronized data transfer for a subset of codes for synchronized data transfer. In another embodiment, the synchronization overhead is reducible by employing a combination of software and hardware by using relaxation data registers and decoders that collectively convert a subset of commands for synchronized data transfer into commands for unsynchronized data transfer.

摘要： The present invention provides a switch memory architecture (SMA) consisting of: (i) processing elements (PE) (ii) memory banks (MB), and (iii) interconnect switches (ISWITCH). The present invention allows for efficient, potentially unbounded data transfer between two adjacent processes by passing a memory handle and the status registers (memory control information) of the MB. This function may be performed by the ISWITCH.
