Abstract: Virtual machines are managed by obtaining software hierarchy information of a current virtual machine to be installed. Then logical memory assigned to the current virtual machine is divided into a private part and a shared part based at least in part upon existing software hierarchy information of at least one virtual machine already installed and the software hierarchy information of the current virtual machine. Then, the shared part of the logical memory is mapped to shared segments of a physical memory, wherein the shared segments are used by at least one installed virtual machine.

Abstract: Global heap allocation technologies in a multi-thread environment, and particularly to a method and system for dynamically adjusting global heap allocation in the multi-thread environment, and more particularly to a method and system for dynamically adjusting global heap allocation by monitoring conflict parameters of the global heap allocation method. The present invention provides a method of dynamically adjusting global heap allocation in multi-thread environment, comprising: identifying a global heap allocation method in an application program; judging whether the global heap allocation method is a multi-thread conflict hot point; and using a local stack to allocate memory space requested by the global heap allocation method in response to a “yes” judging result.

Abstract: A method of accessing a shared data structure in parallel by multiple threads in a parallel application program is disclosed, in which a lock of the shared data structure is granted to one thread of the multiple threads, an operation of the thread which acquires the lock is performed on the shared data structure, then an operation of each thread of the multiple threads which does not acquire the lock is buffered, and finally the buffered operations are performed on the shared data structure when another thread of the multiple threads subsequently acquires the lock. By using this method, the operations of other threads which do not acquire the lock of the shared data structure can be buffered automatically when the shared data structure is locked by one thread, and all the buffered operations can be performed when another thread acquires the lock.
