Abstract: Predicting acceleration in a hybrid system may comprise determining a number of cross system calls in a first host-accelerator computer architecture running a workload. Host machine overhead and accelerator overhead in the first host-accelerator computer architecture associated with each of the cross system calls may be determined. Communication delay associated with each of the cross system calls in the first host-accelerator computer architecture running a workload may be determined. An application response time may be predicted for a candidate application to be run in a second host-accelerator computer architecture, based at least on the determined host machine overhead, the accelerator overhead, and the communication delay associated with each of the cross system calls in the first host-accelerator computer architecture running a workload.

The objects are populated with data from the ERP data.

Abstract: Methods and devices for detecting performance-degrading behaviors include identifying a data source component that inputs data into an application executing on a mobile device, and identifying a data sink component that consumes data output from the application. Using a measured runtime control-flow parameter, a likelihood that the data source component is a critical data resource may be determined. Using the probability value, a behavior model that identifies a mobile device feature associated with the critical data resource may be updated and used to determine whether the software application is malicious. Measured runtime control-flow parameters may include a program execution distance between data source and sink components based on heuristics.

Abstract: Systems and methods are disclosed for handling messages using a messaging bus residing on a mobile device. An example system includes a register module that registers first and second applications. The second application is executing on the mobile device. The system also includes a routing module that receives from the first application a communication in a first format for the second application, determines a second format associated with the second application, and determines whether the first format is different from the second format. When the first format is determined to be different from the second format, the routing module transmits to the second application the communication in the second format. The system further includes a translation module that when the first format is determined to be different from the second format, translates the communication in the first format to the second format.

Abstract: A performance monitoring system is presented for monitoring and tracing individual transactions, where transaction processing includes sending and receiving messages using messaging systems that do not allow the augmentation of existing messages with monitoring system specific correlation information. Agents are deployed to sender and receiver applications that monitor and report transactions. Both sender and receiver applications are instrumented with sensors that detect and report sending or receiving of such immutable messages. Those sensors also extract correlation data from sent and received data allowing the identification of matching corresponding send/receive pairs. A mapping agent is used to retrieve mapping information from a messaging system which may alter the additional message identification data while messages travel through the system. This mapping information is additionally used for the correlation process.

Abstract: A system, method, and computer readable medium for consistent and transparent replication of multi process multi threaded applications. The computer readable medium includes computer-executable instructions for execution by a processing system. Primary applications runs on primary hosts and one or more replicated instances of each primary application run on one or more backup hosts. Replica consistency between primary application and its replicas is provided by imposing the execution ordering of the primary on all its replicas. The execution ordering on a primary is captured by intercepting calls to the operating system and libraries, sending replication messages to its replicas, and using interception on the replicas to enforce said captured primary execution order. Replication consistency is provided without requiring modifications to the application, operating system or libraries.

Abstract: In a multi processing system, packet routing units are arranged in respective middleware layers in first nodes corresponding to memory spaces connected to plural processor cores and perform routing of a packet among parent nodes and child nodes in a tree. The child nodes are user nodes that are objects of respective application layers in the memory spaces. The first nodes are the parent nodes. The user nodes, the first nodes, and a second node in the tree are assigned addresses that identify parent-child relationship of nodes in the tree. The second node is a parent node of the first nodes. The packet routing unit (a1) stores the packet if the source address is identical to an own node address, (a2) transfers the packet to a child node if the source address indicates the child node, and (a3) transfers the packet to a parent node in the other cases.

The method further includes writing the data message as a data window in the sender queue of the sender intermediate layer. The method additionally includes transmitting a front data window of the sender queue of the sender intermediate layer to the receiver queue of the receiver intermediate layer. The method also includes receiving a single receipt-acknowledgement message after a receiver transport layer of the protocol stack has received all of the front data window. The method further includes receiving a commit-acknowledgement message.

Abstract: Described are techniques for executing code performing one or more operations corresponding to scheduling and synchronization primitives. During execution of the code, a call is performed using an application programming interface requesting a first of the operations corresponding to one of said scheduling and synchronization primitives. During runtime in response to said call, it is determined whether to perform the first operation. The determining step uses a set of one or more criteria indicating conditions as to when the scheduling and synchronization primitives are allowed to be performed. The one or more criteria are determined in accordance with a plurality of different platforms. If it is determined that the first operation is allowable and the first operation is to be performed, then the code can be executed on each of the different platforms in a privileged execution mode and a non-privileged execution mode.

Abstract: An improved technique of identifying particular events for alerting within an ENMS involves tagging each incoming event notification as having high priority or normal priority according to a set of rules. Those event notifications tagged as having a normal priority are sent directly to a reporting database, while those tagged as having a high priority are sent directly to an alert evaluation module which is configured to generate an alert as a result of an alert evaluation operation performed on an event notification. In order to comply with reporting requirements, however, the improved technique further involves generating a copy of the event notifications tagged as high priority and sending the copies to the reporting database.
