We present the fast multi-GPU-based calculation of percolation problem on the two-dimensional (2D) square lattice for the multiple GPUs on the large-scale open science supercomputer TSUBAME 2.0.… (More)

The computational performance of multi-GPU applications can be degraded by the data communication between each GPU. To realize high-speed computation with multiple GPUs, we should minimize the cost… (More)

We present the fast multi-GPU-based calculation of percolation problem on the two-dimensional (2D) square lattice for the multiple GPUs on the large-scale open science supercomputer TSUBAME 2.0.… (More)

We present the GPU calculation with the common unified device architecture (CUDA) for the Wolff single-cluster algorithm of the Ising model. Proposing an algorithm for a quasi-block synchronization,… (More)

Paying attention to the difference of density of states, Δln g(E)≡ln g(E+ΔE)-lng(E), we study the convergence of the Wang-Landau method. We show that this quantity is a good estimator to discuss the… (More)

We present new versions of sample CUDA programs for the GPU computing of the Swendsen–Wang multi-cluster spin flip algorithm. In this update, we add the method of GPU-based cluster-labeling… (More)
