Abstract: Exemplary methods, apparatuses, and systems receive a request to bind a socket for a computer application to a tag. The tag is mapped to a network address for each of a subset of interfaces. The request identifies the computer application using a port number. The subset of interfaces includes one or more interfaces within the computer and less than all interfaces within the computer. An interface within the subset of interfaces receives a protocol data unit (PDU) including the port number included in the bind request and a destination address. The received PDU is delivered via the socket in response to resolving a mapping between the tag included in the bind request and the destination address of the PDU and further based upon determining the port number included in the bind request was included in the received PDU.

The hierarchy further includes an inventory level having at least one extension added by the application, wherein data is displayed when the user selects an extension at the inventory level. Another level of the hierarchy is a category extension level having at least one extension added by an application, wherein data is displayed when the user focuses the extensible user interface on a node displayed by an extension added at the inventory level.

Abstract: Methods and systems that detect computer system anomalies based on log file sampling are described. Computers systems generate log files that record various types of operating system and software run events in event messages. For each computer system, a sample of event messages are collected in a first time interval and a sample of event messages are collected in a recent second time interval. Methods calculate a difference between the event messages collected in the first and second time intervals. When the difference is greater than a threshold, an alert is generated. The process of repeatedly collecting a sample of event messages in a recent time interval, calculating a difference between the event messages collected in the recent and previous time intervals, comparing the difference to the threshold, and generating an alert when the threshold is violated may be executed for each computer system of a cluster of computer systems.

Abstract: Techniques for implementing trapless shadow page tables in a virtualized host system are provided. In one embodiment, an SPT accelerator device of the host system can intercept a memory write operation originating from a virtual machine (VM) and directed to a guest OS page table of the VM, where the guest OS page table is stored in a device memory of the SPT accelerator device. The SPT accelerator device can further extract a guest virtual address (GVA)-to-guest physical address (GPA) mapping in the memory write instruction and can translate the GVA-to-GPA mapping into a GVA-to-host physical address (HPA) mapping. The SPT accelerator device can then write the GVA-to-HPA mapping to a shadow page table of the host system.

Abstract: Particular embodiments establish static redirection of a function that is a member of a class to an alternate implementation of the function. A software tool executing on a computer server receives an executable file for an application and a location for an alternate implementation of the function. The function may be written in Objective C. The software tool can be used to locate a structure for the function by traversing serialized metadata in the executable file. The software tool can then be used to modify the metadata in the executable file by updating the value of a selector indicating the location of a current implementation of the function to indicate a location of the alternate implementation. The selector may be included in a element of the structure for the class method. Finally, the application may provide the modified executable file for installation on client devices.

Abstract: Examples provide for automatically provisioning hosts in a cloud environment. A cloud daemon generates a cloud host-state configuration, for a given cloud instance of a host, stored on a cloud metadata service prior to first boot of the given cloud instance of the host. A first boot of a plurality of cloud instances of hosts is performed using a stateless, master boot image lacking host-specific configuration data. On completion of the first boot of a given cloud instance of a host, the cloud host-state configuration is installed on the master boot image to generate a self-configured boot image including host-specific configuration data for the given cloud instance of the host. A second boot is performed on the given cloud instance of the host by executing the self-configured boot image to automatically provision the given cloud instance of the host in the cloud environment.

Abstract: Some embodiments provide a method for managing a set of computing resources. The method imports descriptions of computing resources from several heterogeneous sources. The descriptions specify categories for the computing resources. The different sources use different types of categories for the resource descriptions. Based on the categories specified for the computing resources in the set, the method derives additional categories for at least a subset of the computing resources. The method stores each imported computing resource tagged according to its specified and derived categories, wherein the category tags are used for binding policies to the computing resources.

Abstract: A business method associates provisioning costs with a usage history indicative of user computing demand, and coalesces the cost data to identify an appropriate provisioning level balancing the provisioning cost and the usage demand cost. Conventional computing environments suffer from the shortcoming of being prone to overprovisioning or underprovisioning a user. Such misprovisioning is inefficient because it denotes underutilized computing resources or ineffective and/or disgruntled users. Costs increase either due to the excessive hardware bestowed on the overprovisioned user, or in support costs addressing the underprovisioned user. Configurations herein substantially overcome such shortcomings by defining a policy indicative of overprovisioning and underprovisioning indicators (misprovisioning flags), and defining rules to specify a triggering event indicating the need to reassess the provisioning of a user.

Abstract: An example method of monitoring elements in a cloud computing system includes partitioning an address space of a hierarchy of service elements into a plurality of address subspaces managed by a respective plurality of processing nodes. The method further includes receiving time series data from a service element, routing the time series data to a first processing node based on an address of the service element within the hierarchy, and processing the time series data at the first processing node to update metric data maintained for the service element. The method further includes routing the time series data to a second processing node based on an address of a parent service element above the service element in the hierarchy, and processing the time series data at the second processing node to update metric data maintained for the parent service element.

Abstract: A method and email application enable email attachments to be viewed through a system external to the email application itself in accordance with select categories. The email application creates categories and categorizes the email attachments according to such categories. The email application then maps the categories into a format understandable by the external system for category information and provides the mapped categories to the external system in such format. In response to receiving a request from the external system for the contents of one of the mapped categories and in response to such category having no further subcategories, the email application identifies the email attachments under such category and maps the identified email attachments to file names. The file names are then provided to the external system as the contents of such category.

Abstract: A server receives an update image for transmission to a client and encodes and compresses the update image data using a progressive encoding scheme. In one embodiment, the image data is encoded using progressive JPEG encoding and then into a base64 text string. When insufficient network bandwidth is available to transmit all of the image data for the update image, the server transmits only a first portion of the encoded image data, which is sufficient to fully reproduce the original update image but at a lower quality. When more network bandwidth becomes available, an additional portion of the encoded image data is transmitted to the client. The client is able to append the additional portion to the first portion to refine the image represented at the client. This mechanism may be implemented using unmodified web browsers and servers to remote a computer graphical user interface display.

Abstract: The current document is directed to a storage stack subsystem of a computer system that transfers data between memory and various data-storage devices and subsystems and that processes I/O requests. In one implementation, the disclosed storage stack includes a latency monitor, an I/O-scheduling bypass pathway, and short-circuit switch, controlled by the latency monitor. While the latency associated with I/O-request execution remains below a threshold latency, I/O-scheduling components of the storage stack are bypassed, with I/O requests routed directly to multiple input queues associated with one or more high-throughput multi-queue I/O device controllers. When the latency for execution of I/O requests rises above the threshold latency, I/O requests are instead directed to I/O-scheduling components of the storage stack, which attempt to optimally reorganize the incoming I/O-request stream and optimally distribute I/O-requests among multiple input queues associated I/O device controllers.

The server system can then store the representation of the application in a server-side repository for deployment as a cloud service.

Abstract: Systems and methods described herein enable a residual error image to be added and rendered in an existing HTML canvas using native primitives. A current image and a residual error image containing pixel value differences between the current image and an updated image are received. A positive residual error image and a negative error image are generated from the residual error image. The positive residual error image is added to the current image to generate a partially updated image, and the partially updated image is xored to generate an inverse image. The negative residual error image is added to the inverse image to generate an updated inverse image, and xoring the inverse image to revert the inverse image to generate the updated image.
