A dynamic application environment or system is described that includes a client, a run-time system, and a back-end database. The client comprises a workstation or desktop PC running browser software, such as Microsoft Internet Explorer or Netscape Navigator. The back-end database comprises a back-end (e.g., server-based) database system, such as an SQL-based database system. The run-time system includes a collection or repository module for storing “presentation templates,” a Template Services Module or engine, a Template Parameters Module, and a Database Accessor Module. The presentation templates are employed for presentation of the application to the user interface (at the client). At application run-time, the templates are provided to the Template Services Module, which includes a Template Manager and a Template Parser. These provide generic processing of the templates, which may be assembled to complete a finished product (i.e., run-time application). For instance, the Template Services Module knows how to load and parse a template and then look up its parameters, regardless of the application-specific details (e.g., user interface implementation) embodied by the template. In use, the system is deployed with presentation templates that represent the various client views of the target application, for the various platforms that the application is deployed to. In this manner, when new functionality needs to be added to the system, it may simply be added by expanding the run-time library portion of the system.

Method, apparatus and system embodiments to schedule user-level OS-independent “shreds” without intervention of an operating system. For at least one embodiment, the shred is scheduled for execution by a scheduler routine rather than the operating system. The scheduler routine resides in user space and may be part of a runtime library. The library may also include monitoring logic that monitors execution of a shredded program and provides scheduling hints, based on shred dependence information, to the scheduler. In addition, the scheduler may further optimize shred scheduling by taking into account information about a system's configuration of thread execution hardware. Other embodiments are also described and claimed.

A digital rights management (DRM) system and methodology for a Java client implementing a Java Runtime Environment (JRE). The JRE comprises a Java Virtual Machine (JVM) and Java runtime libraries components and is capable of executing a player application for presenting content that can be presented through a Java program (e.g., a Java application, applet, servlet, bean, etc.) and downloaded from a content server to the client. The DRM system includes an acquisition component for receiving downloaded protected contents; and a dynamic rights management layer located between the JRE and player application for receiving requests to view or play downloaded protected contents from the player, and, in response to each request, determining the rights associated with protected content and enabling viewing or playing of the protected contents via the player application if permitted according to the rights. By providing a Ad DRM-enabled Java runtime, which does not affect the way non-DRM-related programs work, DRM content providers will not require the installation of customized players. By securing the runtime, every Java™ player automatically and transparently becomes a DRM-enabled player.

Presented are embodiments of methods and systems for library-based compilation and dispatch to automatically spread computations of a program across heterogeneous cores in a processing system. The source program contains a parallel-programming keyword, such as mapreduce, from a high-level, library-oriented parallel programming language. The compiler inserts one or more calls for a generic function, associated with the parallel-programming keyword, into the compiled code. A runtime library provides a predicate-based library system that includes multiple hardware specific implementations (“variants”) of the generic function. A runtime dispatch engine dynamically selects the best-available (e.g., most specific) variant, from a bundle of hardware-specific variants, for a given input and machine configuration. That is, the dispatch engine may take into account run-time availability of processing elements, choose one of them, and then select for dispatch an appropriate variant to be executed on the selected processing element. Other embodiments are also described and claimed.

A system and method for automated conversion of a SAS runtime macro language (RML) program to a target language program such as JAVA. RML macros are identified and converted for inclusion in the RML program. A lexer is applied to generate a stream of tokens, including a token type for ambiguous tokens. A context dependent parsing module, including a token filter to resolve ambiguous tokens, assists the parser in generating an abstract syntax tree (AST), which is modified to express RML specific control flow constructs with target language program elements. The elements of the modified AST are replaced with target language templates from a library, with template parameters filled from the corresponding AST element. A run time library is provided for execution of the target language program.

Successor versions of an application service provision runtime library of an application service provision apparatus are provided with corresponding update services to facilitate upgrade of applications to selected ones of the successor versions on request. In various embodiments, a dispatcher of the application service provision apparatus is provided with complementary functions to coordinate the servicing of the upgrade requests. In some embodiments, each of the update services is equipped to upgrade the application from an immediate predecessor version of the runtime library. In other embodiments, each of the update services is equipped to upgrade the application from any predecessor version of the runtime library.

Disclosed herein is a method of analyzing and decrypting encrypted malicious scripts. The method of the present invention comprises the steps of classifying a malicious script encryption method into a case where a decryption function exists in malicious scripts and is an independent function that is not dependent on external codes such as run time library, a case where a decryption function exists and is a dependent function that is dependent on external codes, and a case where a decryption function does not exist; and if the decryption function exists in malicious scripts and is the independent function that is not dependent on the external codes, extracting a call expression and a function definition for the independent function, executing or emulating the extracted call expression and function definition for the independent function, and obtaining a decrypted script by putting a result value based on the execution or emulation into an original script at which an original call expression is located. According to the present invention, unknown malicious codes can be promptly and easily decrypted through only a single decryption algorithm without any additional data. In addition to the decryption of encrypted codes, complexity of later code analysis can also be reduced by substituting constants for all values that can be set as constants in a relevant script.

Embodiments include systems and methods for handling task dependencies in a runtime environment using dependence graphs. For example, a computer-implemented runtime engine includes runtime libraries configured to handle tasks and task dependencies. The task dependencies can be converted into data dependencies. At runtime, as the runtime engine encounters tasks and associated data dependencies, it can add those identified tasks as nodes of a dependence graph, and can add edges between the nodes that correspond to the data dependencies without deadlock. The runtime engine can schedule the tasks for execution according to a topological traversal of the dependence graph in a manner that preserves task dependencies substantially as defined by the source code.

The invention uses a bidirectional metadata management system framework, can support the metadata extracted from other subsystems of the EDW to be stored into the metadata management system, and meanwhile, supports providing the needed metadata information to other subsystems of the EDW, solves the running management problem of the metadata and the EDW, reduces the management difficulty of the EDW, guarantees the accuracy of the metadata and causes the subsystems to efficiently communicate and stably run.

The invention discloses a general purpose computation virtualization implementation method based on dynamic library interception. For overcoming the defects of an existing virtual machine technology in supporting general purpose computation, all functions relevant to the general purpose computation in a virtual environment are called and redirected to a non-virtual environment by intercepting and redirecting a general purpose computation runtime library in real time. Because the non-virtual environment has the general purpose computation capacity, the actual general purpose computation tasks will be completed and the results will be returned to the virtual environment. It is totally transparent for a user in the virtual environment due to the method; on the basis of virtualization of the dynamic library, one physical GPU is virtualized into multiple GPUs logically through the space division multiplexing and time division multiplexing technologies for a GPU pool with GPU resources as allocation objects, and the method supports that one GPU is multiplexed by multiple users.

Prefetching irregular memory references into a software controlled cache is provided. A compiler analyzes source code to identify at least one of a plurality of loops that contain an irregular memory reference. The compiler determines if the irregular memory reference within the at least one loop is a candidate for optimization. Responsive to an indication that the irregular memory reference may be optimized, the compiler determines if the irregular memory reference is valid for prefetching. Responsive to an indication that the irregular memory reference is valid for prefetching, a store statement for an address of the irregular memory reference is inserted into the at least one loop. A runtime library call is inserted into a prefetch runtime library for the irregular memory reference. Data associated with the irregular memory reference is prefetched into the software controlled cache when the runtime library call is invoked.

An application service provision apparatus is provided with one or more components to perform a dispatching and a shared resource monitoring function to allow applications be hosted with multiple versions of a hosting service runtime library in a more efficient manner. The dispatching function, upon receipt of a request for service for an application, determines if the version of the runtime library required is known. If not, the dispatching function turns to the latest version of the runtime library to determine the version required. In one embodiment, the required earlier versions are loaded only on an as needed basis. The shared resource monitoring function, upon detecting aggregated allocation of a shared resource reaching a pre-determined threshold, requests consumers of the shared resource to provide tracked last used times of their allocations. In response, the monitoring function selects a number of the allocations for release, and instructed the shared resource consumers accordingly.

Embodiments of a mobile state object for storing and transporting job metadata on a cluster computing system may use a database as an envelope for the metadata. A state object may include a database that stores the job metadata and wrapper methods. A small database engine may be employed. Since the entire database exists within a single file, complex, extensible applications may be created on the same base state object, and the state object can be sent across the network with the state intact, along with history of the object. An SQLite technology database engine, or alternatively other single file relational database engine technologies, may be used as the database engine. To support the database engine, compute nodes on the cluster may be configured with a runtime library for the database engine via which applications or other entities may access the state file database.

Described is a system and method that separates a managed code runtime library or program into four parts, comprising a header, resources, metadata and method implementations. The metadata and some or all of the resources are maintained in system memory (RAM) the entire time that the program is running. The method implementations and any non-maintained resources are loaded on demand, and then discarded such as via garbage collection. The amount of memory consumed by a managed code program is thus reduced relative to non-separated environments, but because the metadata and selected resources are in memory, the program execution is highly efficient due to significantly reduced access of data in non-volatile storage. The parts of the assembly that are maintained in RAM can be saved as code library files, providing shared use by programs and efficient loading by eliminating any need to again parse a program to identify the separate parts.
