摘要

We implement Monte Carlo algorithms for the simulation of spin-glass systems and optimize our codes for recent multi-core CPU and GPU architectures. We consider both the Ising (binary) and Heisenberg (floating-point) spin-glass models. We provide performance figures for the Intel Nehalem and the IBM Cell/BE CPUs and the Nvidia Tesla C1060 GPU; we also draw a comparison with the performance of dedicated machines, such as the Janus system.
