Software architecture for service of collective memory and method for providing service of collective memory using the same

A method operating on a computer system comprising a processor and a memory for providing a service of a collective volume memory, comprising:

• virtualizing, on the computer system, memories given from nodes to manage the virtualized memories as a collective memory;
• and
• providing, on the computer system, the collective memory service by mapping the collective memory to a selected node through a virtual address space, wherein the driving of a virtual engine includes:
• tracking a service usage condition of the collective memory;
• and
• exchanging a memory page by different scheme based on where the collective memory is positioned,
• wherein the exchanging memory page is performed
• either one of a transaction protocol layer at the time of providing the collective memory service when the collective memory is positioned on a local node according to a tracking result, and exchanging the memory page by using a host channel adaptor (HCA) at the time of providing the collective memory service when the collective memory is positioned on a remote node according to the tracking result.

• wherein the providing of the collective memory service includes:
• processing an interface for supporting the collective memory service;
• mapping the collective memory to the address space to be used as the memory for each node selected through the interface;
• and
• allowing the selected nodes to share the collective memory when the number of the selected nodes is at least two,
• and wherein the exchanging the memory page includes:
• exchanging the memory page by using a transaction protocol layer at the time of providing the collective memory service when the collective memory is positioned on a local node according to a tracking result, and
• exchanging the memory page by using a host channel adaptor (HCA) at the time of providing the collective memory service when the collective memory is positioned on a remote node according to a tracking result.
