An Efficient and Transparent Thread Migration Scheme in the PM2 Runtime System

International audienceThis paper describes a new iso-address approach to the dynamic allocation of data in a multithreaded runtime system with thread migration capability. The system guarantees that the migrated threads and their associated static data are relocated exactly at the same virtual address on the destination nodes, so that no post-migration processing is needed to keep pointers valid. In the experiments reported, a thread can be migrated in less than 75μs

Load balancing HPF programs by migrating virtual processors

This paper explores the integration of load balancing features in the data parallel language HPF targeting semi-regular applications. We show that the HPF virtual processors are good candidates to be the unit of migration. Then, we compare 3 possible implementations and show that threads provide a good trade-off between efficiency and ease of implementation. We finally describe a preliminary implementation. The experimental results, obtained with the Gaussian elimination with partial pivoting are promising
