A task processing method and virtual machine are disclosed. The method includes selecting an idle resource for a task; creating a global variable snapshot for a global variable; executing the task, in private memory space in the selected idle resource; after the execution of the task is complete, acquiring a new global variable snapshot corresponding to the global variable, and acquiring an updated global variable according to a local global variable snapshot and the new global variable snapshot; and determining whether a synchronization variable of a to-be-executed task in a task synchronization waiting queue includes the current updated global variable, and if the synchronization variable of the to-be-executed task in the task synchronization waiting queue includes the current updated global variable, putting the task into a task execution waiting queue.

Task processing method and virtual machine

A task coordination apparatus in a computing system having a distributed shared memory (DSM) coordinates the execution of two related tasks, wherein the second task has an execution variable which is modified by the first task. The task coordination apparatus creates a snapshot of a memory space in the distributed shared memory assigned to the first task and a cooperation watching area of the second task. The cooperation watching area contains a memory address pointing to a location where the execution variable of the second task is stored in the memory space assigned to the first task. The first task is allocated to a first computing node for execution, and the memory space assigned to it is updated according to the execution result. After updating the memory space, the second task is allocated to a second computing node for execution using the execution variable updated by the first task.
