چکیده
In this white paper we describe work done on the development of an efficient iterative solver for lattice QCD based on the Algebraic Multi-Grid approach (AMG) within the tmLQCD software suite. This development is aimed at modern computer architectures that will be relevant for the Exa-scale regime, namely multicore processors together with the Intel Xeon Phi coprocessor. Because of the complexity of this solver, implementation turned out to take a considerable effort. Fine tuning and optimization will require more work and will be the subject of further investigation. However, the work presented here provides a necessary initial step in this direction.

Lattice QuantumChromodynamics (LQCD) is currently the only known model independent, non perturbative computational method for calculations in the theory of the strong interactions, and is of importance in studies of nuclear and high energy physics. LQCD codes use large fractions of supercomputing cycles worldwide and are often amongst the first to be ported to new high performance computing arc...

This white paper describes parallelization of the Slilab code with OpenMP for a shared-memory execution model when focusing on the multiphase phase flow simulations, such as fiber suspensions in turbulent channel flows. In such problems the motion of the ”second phase fibre” is frequently crossed over the distributed domain boundary of the ”first phase fluid”, which in turn reduces the work-bal...

The Intel Xeon Phi architecture from Intel Corporation features parallelism at the level of many x86-based cores, multiple threads per core, and vector processing units.

متن کاملLattice QCD with Domain Decomposition on Intel
The gap between the cost of moving data and the cost of computing continues to grow, making it ever harder to design iterative solvers on extreme-scale architectures. This problem can be alleviated by alternative algorithms that reduce the amount of data movement. We investigate this in the context of Lattice Quantum Chromodynamics and implement such an alternative solver algorithm, based on do...
متن کاملConjugate gradient solvers on Intel Xeon Phi and NVIDIA GPUs
Lattice Quantum Chromodynamics simulations typically spend most of the runtime in inversions of the Fermion Matrix. This part is therefore frequently optimized for various HPC architectures. Here we compare the performance of the Intel R Xeon Phi TM to current Kepler-based NVIDIA R Tesla TM GPUs running a conjugate gradient solver. By exposing more parallelism to the accelerator through inverti...
