| Outline of Final Research Achievements |
We improved our proposed task-palallel language, called Tascell, and implementations of sevelal application programs using Tascell, as a research project to develop a parallel language that can deliver good performance in distributed memory environemts for practical graph applications. We improved strategies of task assignment to Tascell workers, namely strategies of how a thief worker chooses a victim worker at a work-steal attempt. We also improved our MPI-based implementation of inter-node communication in Tascell. Using the imporoved implementation of Tascell, we developed and tuned several task-parallel applications such as graph mining and construction of Hierarcical matrices, and we achieved good performance on distributed memroy systems including a supercomputer.
