Summary Homogeneous cluster architectures, which used to dominate high-performance computing (HPC), are challenged today by heterogeneous approaches utilizing accelerator or co-processor devices. The DEEP (Dynamical Exascale Entry Platform) project i

We present results for the b \bar b spectrum obtained using an O(M_bv^6)-correct non-relativistic lattice QCD action, where M_b denotes the bare b-quark mass and v^2 is the mean squared quark velocity. Propagators are evaluated on SESAM's three sets

In a full QCD lattice study with Nf = 2 Wilson fermions, we seek to optimize the signals for the disconnected contributions to the Pion Nucleon Sigma term σN. We demonstrate, in form of a numerical analysis, that — in order to achieve a tolerable

Moments of light cone quark density, helicity, and transversity distributions are calculated in unquenched lattice QCD at $\beta = 5.5$ and $\beta = 5.3$ using Wilson fermions on $ 16^3 \times 32 $ lattices. These results are combined with earlier ca
