This paper presents optimizations in a high-performance conjugate gradient benchmark (HPCG) for multi-core Intel® Xeon® processors and many-core Xeon Phi™ coprocessors. Without careful optimization, the HPCG benchmark under-utilizes the compute r

Lattice Quantumchromodynamics (QCD) is a powerful tool to numerically access the low energy regime of QCD in a straightforward way with quantifyable uncertainties. In this approach, QCD is discretized on a four dimensional, Euclidean space-time grid

We present a new approach for multithreaded communication and asynchronous progress in MPI applications, wherein we offload communication processing to a dedicated thread. The central premise is that given the rapidly increasing core counts on modern

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
