Systems and method for malware detection

A system and method for distinguishing human input events from malware-generated events includes one or more central processing units (CPUs), one or more input devices and memory. The memory includes program code that when executed by the CPU causes the CPU to obtain a first set of input events from a user utilizing the input device. The first input events are used to obtain or derive a feature indicative of the user, such as a multi-dimensional feature vector as provided by a support vector machine. Second input events are then obtained, and the second input events are classified against the feature to determine if either the user or malware initiated the second input events.

The invention relates to a dynamic deployment method for virtual machines. The method comprises the following steps: dividing residual resources of each dimension on a physical machine by demanded resource quantity of a corresponding dimension of a to-be-deployed physical machine so as to obtain a ratio sequence, screening out the minimum value of ratios in the sequence and taking the minimum value as the maximum accommodating number of the physical machine to a to-be-deployed virtual machine; selecting a physical machine with the largest maximum accommodating number, and judging whether the physical machine has enough resources to accommodate the to-be-deployed virtual machine; if the value of the maximum accommodating number of the target physical machine is greater than or equal to 1, deploying the virtual machine to the physical machine; and if the maximum accommodating number of the target physical machine is less than 1, outputting that the deployment of the virtual machine fails. By using the method disclosed by the invention, a 'short board' phenomenon, namely, resources of other dimensions are wasted because of the lack of resources of some dimension of a physical machine in a cluster, can be avoided, and the resource utilization ratio of the physical machine can be increased.

Extensible centralized dynamic resource distribution in a clustered data grid

ActiveUS20120297056A1Avoid bottlenecksBottlenecks caused by a single point of coordination can be preventedDigital computer detailsDatabase distribution/replicationClustered dataDynamic resource
A centralized resource distribution is described where the decision portion of partitioning data among cluster nodes is made centralized while the actual mechanics to implement the partitioning remain a distributed algorithm. A central distribution coordinator is used to create an extensible central strategy that controls how the data will be partitioned across the cluster. The work to implement this strategy is performed by all of the members individually and asynchronously, in accordance with a distributed algorithm. The central strategy can be communicated to all cluster members and each member can perform the partitioning as it relates to itself. For example, in accordance with the distributed algorithm, one node may decide that it needs to obtain a particular partition in light of the central strategy and carry out the necessary steps to obtain that data, while other nodes may be asynchronously performing other individual partition transfers relevant to those particular nodes.

Using constraint-based heuristics to satisfice static software partitioning and allocation of heterogeneous distributed systems

Systems and methods automatically design a system's architecture by modeling the architectural complexity of large-scale distributed systems to drive a partitioning and allocation algorithm. The result is a configuration based on the structure of the software tasks and data access, and the capacities of the hardware. Coupling and cohesion are relative, dependent on the ratio of load to capacity, and not independent software characteristics. The partitioning and allocation algorithm includes tradeoffs between processor utilization, memory utilization, inter-processor communication, and peripheral contention. The systems and methods take into account both precedence constraints and the directional flow of data. Further aspects include interleaving the decisions of database segmentation and software distribution. This approach is demonstrated with a simplified example of a real distributed system.
