摘要:
Systems, methods, and computer program products for processing data are disclosed. A method according to one embodiment includes reading a data processing instruction locally called by a virtual work unit; optimizing the read data processing instruction; and performing data processing for the virtual work unit using the optimized data processing instruction. The step of optimizing the read data processing instruction may include one or more of: merging data processing instructions from different virtual work units for same data, and analyzing data processing instructions from different virtual work units to select suitable data processing timing. The data processing method is executed in a virtual environment.

A Pub-Sub messaging method and system is disclosed. The method comprises: receiving a plurality of Pub-Sub messages; judging whether the plurality of Pub-Sub messages are similar; aggregating similar Pub-Sub messages to generate an aggregated Pub-Sub message; and transmitting the aggregated Pub-Sub message. Correspondingly, a message de-aggregating method comprises: receiving an aggregated Pub-Sub message, wherein the aggregated Pub-Sub message is generated by aggregating a plurality of similar Pub-Sub messages; de-aggregating the aggregated Pub-Sub message to recover the plurality of Pub-Sub messages; and transmitting the plurality of Pub-Sub messages.
摘要:
A method for realizing content sharing among mobile terminals comprises: receiving an index of access content sent by a requesting mobile terminal; looking up a shareable content index table for the index of the access content; and sending identification information of a mobile terminal having the index of the access content to the requesting mobile terminal if the index of the access content is found, so that the requesting mobile terminal obtains the requested access content from the mobile terminal having the index of the access content via wireless communication.

The present invention discloses a method and system for processing test cases for applications to be tested. The method includes evaluating two applications to be tested; obtaining test cases for the two applications to be tested and determining resources and execution times needed by the test cases for the two applications to be tested. According to the compatibility relationship between the two applications to be tested, and the resources and execution times needed by the test cases for the two applications to be tested, the test cases for the two applications to be tested are clustered to a virtual machine instance to test the test cases for the two applications to be tested on the virtual machine instance.
摘要:
A method and system for controlling load admission rate of an application server is provided. In the method, actual heap utilization and load admission rate of the application server in current control cycle are detected; based on the detected actual heap utilization and load admission rate, load characteristics variation parameters of the application server are estimated; and control gain of a feedback controller is calculated based on the load characteristics variation parameters; the feedback controller calculates desired load admission rate of the application server in next control cycle by using the calculated control gain. The load admission rate of the application server can be adaptively controlled by tracking changes in workload characteristics of the application server, such that the actual heap utilization of the application server is maintained at or close to target heap utilization.
