| Outline of Final Research Achievements |
Fault resiliency is an important issue for post-petascale computing environments. In order to achieve fault resiliency of application programs running on such computers, we propose, design and develop a prototype system of a highly available distributed scheduler and investigate its performance characteristics.
We first designed a highly available distributed self-scheduler and developed a Java-based prototype system using Apache ZooKeeper, and showed its availability and scalability. Then, we implement the proposed scheduler into the C-based falanx middleware developed using User Level Fault Mitigation (ULFM) MPI. We showed the feasibility of the proposed scheduler from the experiments.
