Multi-GPU-Based Calculation of Percolation Problem on the TSUBAME 2.0 Supercomputer
SESSION: Research Poster Reception
EVENT TYPE: Posters and Electronic Posters
TIME: 5:15PM - 7:00PM
SESSION CHAIR: Torsten Hoefler
AUTHOR(S):Yukihiro Komura, Yutaka Okabe
ROOM:East Entrance
ABSTRACT:
We present the multi-GPU-based calculation of percolation
problem on the 2D regular lattice for the multiple GPUs
on the large-scale open science supercomputer TSUBAME 2.0.
Recently, we presented the multiple GPU computing with the
common unified device architecture (CUDA) for the cluster labeling.
We adapt this cluster labeling algorithm to the percolation
problem. In addition, we modify this cluster labeling algorithm
in order to simplify the analysis for the percolation. As a result,
we realized the large scale and rapid calculations without a decay
of computational speed on the analysis for the percolation, and
the calculation time for the 2D bond percolation with L=65536
is obtained as 180 milliseconds per a single realization.
