- Abstract
- In the cluster environment where nodes are connected via high speed network, approach to utilize remote memory like local memory has been considered as a cost effective way to run large memory application. For the users of HPC cluster(or supercomputer) to run large memory application without administrator's support, we explored the feasibility of user-level remote memory extension to remote memory. We suggest a remote memory library model which extends the virtual address space of the large memory application process to remote memory. It includes user-level page fault handling mechanism based on temporal page mapping. We developed a test program to show if the user-level remote memory extension is feasible. From the experimental test, we found that user-level remote memory extension work well for applications where throughput is more important rather than latency.
