| 20090037501 | METHOD AND SYSTEM FOR MANAGING MEMORY FOR A PROGRAM USING AREA - If garbage collection is executed in every thread-local heap in order to secure processing responsiveness, a memory area may be fragmented or collectable areas may be reduced as the program execution proceeds. To overcome such problems, memory is divided into an area where thread specific data is allocated and an area where referenceable data from other threads is allocated, and is managed separately. More specifically, data that is referenced specifically by each thread is allocated to a thread-local heap, while data that is referenced from other threads is allocated to a global heap. | 02-05-2009 |
| 20090037684 | MEMORY MANAGEMENT METHOD AND COMPUTER USING THE METHOD - Memory management by garbage collection involves a memory area that is allocated in a computer. Data is created in the memory area in accordance with a program executed by a processor of the computer, and it is checked whether or not data necessary to execute the program exists in the memory area to be released, in response to an explicit instruction to release the memory area. As a result of the check, if data necessary to execute the program does not exist in the memory area, the memory area is released. As a result of the check, if data necessary to execute the program exists in the memory area, the data is moved to a memory area different from the memory area to be released. | 02-05-2009 |
| 20100077170 | MEMORY MANAGEMENT METHOD AND COMPUTER USING THE SAME - The present invention provides a memory management method, including the steps of: securing a memory area by a program executed by a computer; storing an object in the memory area in accordance with the execution of the program; bringing the memory area into a release reservation state in accordance with the program instructing the memory area to be released; moving the object to a memory area not to be released while another object in the memory area not to be released and not to be brought into the release reservation state refers to the object in the memory area to be released including the memory area to be brought into the release reservation state; and releasing the memory area to be released. | 03-25-2010 |
| 20100153922 | METHOD OF DETECTING MEMORY LEAK CAUSING PORTION AND EXECUTION PROGRAM THEREOF - With regard to a plurality of data stored in a memory, relationship of data is grasped twice after a time interval therebetween. Next, increased data C | 06-17-2010 |
| 20100250629 | MEMORY MANAGEMENT METHOD AND COMPUTER - A memory management method is provided to manage a memory in which areas of a garbage collected Java heap memory and a non-garbage collected external heap memory can be secured, by using a program executed by a processor in a computer. If it is judged that there is no reference to all data arranged in the external heap memory or starting point data of reference relations included in the all data, from data arranged outside the external heap memory, then the external heap memory is judged to be capable of being deallocated. As a result, it becomes possible to implement memory management in which garbage collection needing a long time program stop is not conducted and an additional API is not used. | 09-30-2010 |
| 20100274947 | MEMORY MANAGEMENT METHOD, MEMORY MANAGEMENT PROGRAM, AND MEMORY MANAGEMENT DEVICE - In a virtual machine system built from a plurality of virtual machines, the utilization efficiency of utilized physical memory is raised. A memory management method in which a virtual machine environment, constituted by having one or several virtual machines and a hypervisor part for operating the same virtual machines, is built on a physical machine and in which: a virtual machine operates an allocation processing part and an application part, application part making a physical memory processing part allocate unallocated physical memory to a memory area and allocation processing part transmitting, when unallocated physical memory is scarce, an instruction for the release, from memory areas utilized by each application part, of memory pages for which physical memory is assigned but not used. | 10-28-2010 |
| 20110099403 | SERVER MANAGEMENT APPARATUS AND SERVER MANAGEMENT METHOD - A server management apparatus for lowering migration costs during scale-in/scale-out and workload consolidation of a cluster system(s) to thereby reduce power consumption is disclosed. The apparatus manages a physical server group which renders operative a virtual server group thereon and, when putting into practice a cluster system including a plurality of virtual servers placed in the physical server group, manages the layout state of virtual servers pursuant to the load state of the virtual server group. When executing scale-in, a virtual server operating on a physical server with the minimum number of operative virtual servers is specified as a shutdown target. When executing scale-out, a workload variation is predicted to control a scale-out destination of cluster system so that load variation-resembled cluster systems gather on the same physical server. The scale-in execution timing is delayed if the predicted load variation tends to rise and accelerated if it falls. | 04-28-2011 |
| 20110213943 | MEMORY MANAGEMENT METHOD AND COMPUTER USING THE METHOD - Memory management by garbage collection involves a memory area that is allocated in a computer. Data is created in the memory area in accordance with a program executed by a processor of the computer, and it is checked whether or not data necessary to execute the program exists in the memory area to be released, in response to an explicit instruction to release the memory area. As a result of the check, if data necessary to execute the program does not exist in the memory area, the memory area is released. As a result of the check, if data necessary to execute the program exists in the memory area, the data is moved to a memory area different from the memory area to be released. | 09-01-2011 |
