We optimize codes implementing Monte Carlo simulations of spin-glass systems for some multi-core CPU and GPU architectures. We consider both the binary Ising and floating-point Heisenberg spin-glass models in 3 dimensions. We provide performance figures for the Intel Nehalem quad-core and the IBM Cell/BE CPUs and the Nvidia Tesla C1060 GPU; for the binary model we also draw a comparison with the performance of dedicated computers, such as the Janus machine. © 2012 Springer-Verlag.

Abstract
We optimize codes implementing Monte Carlo simulations of spin-glass systems for some multi-core CPU and GPU architectures. We consider both the binary Ising and floating-point Heisenberg spin-glass models in 3 dimensions. We provide performance figures for the Intel Nehalem quad-core and the IBM Cell/BE CPUs and the Nvidia Tesla C1060 GPU; for the binary model we also draw a comparison with the performance of dedicated computers, such as the Janus machine. © 2012 Springer-Verlag.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
