SERVER USING HIERARCHICAL STURCTURED MEMORY MANAGEMENT TECHNIQUE ON MULTI PROCESS

摘要

According to an embodiment of the present disclosure, a server implementing the multi-process system is disclosed. The server includes: a global memory management unit that manages memory of all processes; A plurality of process memory management units for managing memory for at least one process among the entire processes; And a plurality of thread memory management units for managing memory of threads included in any one of the entire processes. Including, wherein the global memory management unit determines whether to allocate the first available memory in response to a first memory allocation request of a first process memory management unit, which is one of the plurality of process memory management units, and When allocation is not allowed, a request for securing a first available memory is transmitted to at least one second process memory management unit included in the plurality of process memory management units, and a third process memory management unit that is any one of the plurality of process memories In response to a second memory allocation request of the first thread memory management unit managed by the third process memory management unit, it is determined whether to allocate the second available memory, and when the allocation of the second available memory is not allowed, the third process A request for securing a second available memory may be transmitted to at least one second threaded memory management unit managed by the memory management unit.
