Problems solved by technology

The problem with this solution is that the resources occupied by the abnormal logical partition are also given up.
If there is no way to dynamically allocate the resources of the dead logical partition to the live logical partition, the computer industry will continue to suffer from the waste of resources when the logical partition occupying the resource dies in the shared resource environment

Embodiment Construction

[0020] According to a preferred embodiment of the present invention, when a logical partition dies, the dynamic resource allocation mechanism tries to allocate all resources occupied by the dead logical partition to the active logical partition after closing the dead logical partition. In this manner, the resources occupied by the dead logical partitions will not be wasted by closing the dead logical partitions.

[0021] Referring to FIG. 1, computer system 100 is an enhanced IBM iSeries computer system, which represents a suitable class of computer systems capable of supporting logical partitioning and dynamic resource allocation in accordance with a preferred embodiment. Those skilled in the art should understand that the mechanism and device of the present invention are also applicable to any computer system that supports logical partitions. As shown in FIG. 1 , computer system 100 includes one or more processors 110 connected to main memory 120 , mass storage interface 130...

Abstract

A dynamic resource allocation apparatus and method detects when a logical partition is dead, and attempts to allocate any of the dead logical partition's shared resources to a live logical partition after shutting down the dead logical partition. This allows the shared resources of the dead logical partition to be used, where possible, by shifting the resources to one or more logical partitions that are still alive. In this manner the shared resources are used to the fullest extent possible, without wasting shared resources simply because they are owned by a dead logical partition.

Description

technical field [0001] The present invention relates to data processing, and in particular to the allocation of shared resources of computer systems. Background technique [0002] Since the dawn of the computer age, computer systems have grown into extremely complex devices that can appear in many different configurations. A computer system typically includes a combination of hardware (eg, semiconductor devices, circuit boards, etc.) and software (eg, computer programs). As the development of semiconductor processing and computer architecture pushes the performance of computer hardware higher and higher, more complex computer software has been developed to take advantage of the higher performance of hardware, making today's computer systems far more powerful than they were just a few years ago. [0003] The combination of hardware and software on a particular computer system defines the computing environment. Therefore, different computer hardware platforms and different c...
