Performance Characterization of Graph500 on a distributed-memory based Supercomputer

[Abstract]
Graph500 has emerged as a new benchmark of ranking supercomputers with the motivation that large-scale graph analysis is becoming greatly important application. It is well studied that Graph algorithms are suitable for shared-memory based supercomputers such as Cray XMT. Recent trend of Linpack-based supercomputer ranking shows that heterogeneous and distributed-memory based supercomputers with tremendous amount of GPGPUs greatly achieves top-ranked performance score. However, the performance characteristics of large-scale graph analysis like Graph500 on such a distributed-memory supercomputer has not yet been well investigated. This paper shows thorough study on the performance characteristics of Graph500 using 4th-ranked supercomputer, TSUBAME.
