| Outline of Final Research Achievements |
In this research, we have supported fault tolerance features in a multi-SPMD programming/execution environment, where tasks in a workflow are executed in distributed parallel. The programming environment adopts multi-programming methodologies across multi-architectural levels, such as Numa-core groups in a node, nodes in a cluster, a cluster of clusters, to realize scalability. To achieve a fault tolerance and resilience mechanism without any modification of the application’s source code, we have developed middleware to detect errors in remote programs and extended workflow scheduler to realize fault resilience.
