Abstract:

We propose a data migration mechanism that allows an explicit and controlled mapping of data to memory. While read or write copies of each data element can be assigned to any processors memory,longer term storage of each data element is assigned to a specific location in the memory of a particular processor. Our proposed integration of a data migration scheme with a compiler is able to eliminate the migration of unneeded data that can occur in multiprocessor paging or caching. The overhead of adjudicating multiple concurrent writes to the same page or cache line is also eliminated. We present data that suggest that the scheme we suggest may be a practical method for efficiently supporting data migration. KT
