계산 그리드의 소규모 리눅스 PC 클러스터에서 소용량 메모리의 효율적 활용을 위한 메모리설정 기법

초록

In spite of efforts on efficient utilization of resources participating in the Grid, it is not straightforward to attain high utilization due to usage patterns including the popularity of software. In computational Grid, some specific engineering application hits a high rate but there is no certainty that the software is installed at a cluster with high capacity, i.e. main memory. In the cluster’s perspective of the software, the cluster need complete the requested tasks with its restrictive memory. The restrictive memory incurs frequent thrashing, and this work aims at the least thrashing possible by an effective memory utilization scheme.
