Graphics Processing Units (GPUs) are having a transformational effect on numerical lattice quantum chromo- dynamics (LQCD) calculations of importance in nuclear and particle physics. The QUDA library provides a package of mixed precision sparse matrix linear solvers for LQCD applications, supporting single GPUs based on NVIDIA's Compute Unified Device Architecture (CUDA). This library, interfaced to the QDP++ Chroma framework for LQCD calculations, is currently in production use on the "9g" cluster at the Jefferson Laboratory, enabling unprecedented price performance for a range of problems in LQCD. Nevertheless, memory constraints on current GPU devices limit the problem sizes that can be tackled. In this contribution we describe the parallelization of the QUDA library onto multiple GPUs using MPI, including strategies for the overlapping of communication and computation. We report on both weak and strong scaling for up to 32 GPUs interconnected by InfiniBand, on which we sustain in excess of 4 Tflops.
@cite_18: The implementation of a proof-of-concept Lattice Quantum Chromodynamics kernel on the Cell processor is described in detail, illustrating issues encountered in the porting process. The resulting code performs up to 45 GFlop s per socket (without inter-node parallel communications), indicating that the Cell processor is likely to be a good platform for future Lattice QCD calculations.
@cite_4: In this processing solution supplying apparatus, when restarting the hydrophobic process, the air in the supply pipe is exhausted outside before performing the hydrophobic process by using a transfer gas, bypassing the process chamber. Thus, a large-sized mist of HMDS staying inside the supply pipe is not supplied to the wafer as it is, and after restarting the hydrophobic process after a prolonged stoppage of the adhesion apparatus, the vapor or mist of HMDS can be supplied uniformly to the wafer.
@cite_1: 
@cite_20: A device for straightening wire, particularly coiled wire, is disclosed. The device includes at least two banks of rollers that are pivotally mounted with respect to a supporting base.
LQCD has also been implemented on other heterogeneous devices, primarily on the Cell Broadband Engine. Efforts in this direction have been reported in @cite_20 @cite_1 as part of the QCD Parallel Computing on the Cell Broadband Engine'' (QPACE) project and elsewhere @cite_4 @cite_18 .
