Abstract: The present invention relates to mechanisms for managing VM instances. More specifically, the mechanisms provide at least one VM instance in a resource pool. A configuration requirement is provided with respect to a virtual machine, the configuration requirement describing a first amount of application resources to be installed on the virtual machine. Based on the configuration requirement, a resource tree is built describing a dependency relation between the first amount of application resources. At least one VM instance corresponding to a sub-path of the resource tree is provided in the resource pool, where on each VM instance in the at least one VM instance there are installed application resources included in the sub-path.

Abstract: Embodiments of the invention relate to deploying a program module. The deploying includes obtaining a data dependency relationship between the program module and multiple to-be-deployed program modules, and a specific start order. In response to a request to install and configure the program module, data on which the program module depends are identified according to the data dependency relationship. In addition, the program module is installed and configured responsive to the identified data. The program module is started in response to completion of a startup of program modules required to be started before the program module as specified by the specific start order.

Abstract: Embodiments of mechanisms for forming a micro-electro mechanical system (MEMS) device are provided. The MEMS device includes a substrate and a MEMS sensor over the substrate. The MEMS sensor includes a floating heater disposed over the substrate. The MEMS sensor further includes a heat sink disposed over the substrate and at a side of the floating heater, and the heat sink has an air gap with the floating heater. The MEMS sensor further includes a first plurality of vias formed through the heat sink and thermally connected to the first substrate.

Abstract: A method and system for deploying a service in a cloud computing system. The method comprises collecting metadata information related to the service, building a list including a plurality of potential service endpoints by using the metadata information, and validating the potential service endpoints in the list. With the method, mapping between service and service endpoints is effectively processed while deploying the service.

Abstract: The present invention relates to application program logs. In particular, the invention relates to a method and a system in which an original log method of an application program is optimized and newly injected to the application program. According to one aspect of the present invention, there is provided a method for optimizing an application program log record, comprising: identifying an original log method of an application program; separating a character string parameter in the original log method into a constant part and a variable part; establishing a correspondence flag between the constant part and the variable part; constituting an optimized log method by the constant part, the variable part and the correspondence flag; and replacing the original log method with the optimized log method through a code injection. With the above method, the hard disk storage amount of the log record and the IO operation frequency can be reduced.

Abstract: In a field of software configuration, a technology of migrating and configuring software rapidly by determining a correspondence between device specific information and a specific configuration file location recording such information. According to one aspect of the present invention, a method for software fast configuration is provided comprising: obtaining and analyzing a software configuration program to identify a method related to the device specific information in the software configuration program; adding an identification to the device specific information obtained by the method related to the specific device information; and determining a correspondence between the device specific information and its record location in a software configuration file based on the added identification.

Abstract: A computer-implemented method for monitoring an object-oriented application is disclosed. A transaction-representative-digraph is built based upon a real-time running of the application, and the digraph contains nodes of a plurality of replaceable classes. A key node is selected based upon invocation relationships between the nodes. A monitor program is instrumented at the selected key node.

Abstract: A method and system of deadlock detection in a parallel program, the method comprising: recording lock events during the operation of the parallel program and a first order relation among the lock events; converting information relevant to the operation of the parallel program into gate lock events and recording the gate lock events; establishing a second order relation among the gate lock events and lock events associated with the gate lock events and adding the second order relation to the first order relation; constructing a lock graph corresponding to the operation procedure of the parallel program based on the added first order relation; and performing deadlock detection on the constructed lock graph. The deadlock detection method of the invention can improve the accuracy of deadlock detection without depending on the deadlock detection algorithm per se, and can be applied with facility to various development environments and reduce development costs.

Abstract: The present invention provides an image processing system for scanning a rectangular document. The system comprises a scanner with a scanning module and a computer. The computer has a memory, a processor, a scanner control program, and an image processing program. Depression of a start button generates a start signal that prompts the image processing system to rotate the document image from the scanned rectangular document by a tilting angle as well as to correct the image shape based on angle variation. This produces a straight and rectangular document image.
