We propose a lightweight process migration mechanism and an adaptive memory prefetching scheme called AMPoM (adaptive memory prefetching in openMosix), whose goal is to reduce the migration freeze time in openMosix while ensuring the execution efficiency of migrants. To minimize the freeze time, our system transfers only a few pages to the destination node during process migration. After the migration,...
We study the load rebalancing problem in a heterogeneous grid environment that supports process migration. Given an initial assignment of tasks to machines, the problem consists of finding a process reassignment that achieves a desired better level of load balance with minimum reassignment (process migration) cost. Most previous algorithms for related problems aim mainly at improving the balance level...
