Abstract

The invention discloses method, which includes: according to the NVDIMM memory allocation request, the state symbol of corresponding process is installed to be the NVDIMM memory allocation, and the ID information of the process is ontained. The ID information is transmitted to a kernel. According to the ID information, memory is allocated by the kernel for the process in the NVDIMM memory. The memory of users' programs which are important for users can be allocated on the NVDIMM. So data of users can be preserved well when the abnormal conditions such as power-off occur. A linux system application program memory management system also has above-mentioned beneficial effects.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a Linux system application program memory management method and system. Background technique [0002] First of all, with the rapid development of related technologies such as big data and cloud computing, the number of devices connected to the Internet has continued to increase, and by 2015, it had reached 15 billion. The pressure on the data center has also increased, and only by adopting new technologies can its efficiency and performance be further improved. [0003] At present, the calculation results and service information of the computer system are temporarily stored in the memory, and these data will be lost after the system is powered off, and may even cause the entire system to crash. Therefore, how to effectively avoid the heavy loss of user data due to data loss when the system is abnormal is a technical problem to be solved by those skilled in the art. Contents ...
