A system has a collection of central processing units. Each central processing unit is connected to at least one other central processing unit and has a path into flash memory resources. A central processing unit supports a mapping from a data address space, to a flash memory virtual address space, to a flash memory virtual page number to a flash memory physical address space.

An attestation system for asserting and verifying assertions of a known-good state of a computer system is provided. The attestation system allows a challenger and a prover to conduct an attestation so that the challenger can verify an assertion of the prover. To conduct the attestation, the prover sends, as an assertion of its state, a combined measurement of resources along with a constituent measurement of each resource to the challenger. The challenger verifies the assertion by verifying that the asserted constituent measurements represent known-good measurements and verifying that the asserted combined measurement can be generated from the asserted constituent measurements. To verify the asserted constituent measurements, the challenger determines whether each asserted constituent measurement for a resource is a known-good measurement for that resource. To verify the asserted combined measurement, the challenger generates a combined measurement from the asserted constituent measurements received from the prover.

Installation of an application on a test bed machine is monitored to generate a streamed application set of a stream enabled version of the application. Execution of the application on the test bed machine is monitored to generate the streamed application set of the stream enabled version of the application. Stream enabled application pages and a stream enabled application install block to form the streamed application set is generated based on the monitoring of the installation of the application and the monitoring of the execution of the application on the test bed machine. The stream enabled application install block is provided to a client device. A request for a stream enabled application page of the stream enabled application pages is received from the client device. The stream enabled application page is provided to the client device for continued execution of the stream enabled version of the application.

Intelligent network streaming and execution system for conventionally coded applications

An intelligent network streaming and execution system for conventionally coded applications provides a system that partitions an application program into page segments by observing the manner in which the application program is conventionally installed. A minimal portion of the application program is installed on a client system and the user launches the application in the same ways that applications on other client file systems are started. An application program server streams the page segments to the client as the application program executes on the client and the client stores the page segments in a cache. Page segments are requested by the client from the application server whenever a page fault occurs from the cache for the application program. The client prefetches page segments from the application server or the application server pushes additional page segments to the client based on the pattern of page segment requests for that particular application. The user subscribes and unsubscribes to application programs, whenever the user accesses an application program a securely encrypted access token is obtained from a license server if the user has a valid subscription to the application program. The application server begins streaming the requested page segments to the client when it receives a valid access token from the client. The client performs server load balancing across a plurality of application servers. If the client observes a non-response or slow response condition from an application server or license server, it switches to another application or license server.

An client-side performance optimization system for streamed applications provides several approaches for fulfilling client-side application code and data file requests for streamed applications. A streaming file system or file driver is installed on the client system that receives and fulfills application code and data requests from a persistent cache or the streaming application server. The client or the server can initiate the prefetching of application code and data to improve interactive application performance. A client-to-client communication mechanism allows local application customization to travel from one client machine to another without involving server communication. Applications are patched or upgraded via a change in the root directory for that application. The client can be notified of application upgrades by the server which can be marked as mandatory, in which case the client will force the application to be upgraded. The server broadcasts an application program's code and data and any client that is interested in that particular application program stores the broadcasted code and data for later use.

Client-side performance optimization system for streamed applications

The present invention relates to a mechanism for copying selected routines from shared libraries into application programs thereby generating optimized application programs for more rapid execution of the various applications within a computer system. Since optimized programs occupy space on disk and in RAM, programs are preferably selected for optimization based on their frequency of execution and the frequency with which calls are made to the shared libraries. Profile information may be used to identify the execution efficiency of the various application programs and thereby identify the best candidates for optimization. Further, profile information may be employed to copy individual routines contained within the libraries rather than having to copy an entire library where only one routine within the library was of interest. Pinpointing the individual routines of interest in this manner may help conserve disk space by copying only those routines which are most needed to optimize program execution performance.
