Benefits of Intel Xeon Phi Knights Landing (KNL) systems in computing cost are examined with tight-binding simulations of large-scale electronic structures that involve sparse system matrices whose dimensions normally reach several tens of millions. Speed and energy usage of our in-house Schroedinger equation solver are benchmarked in KNL systems for realistic modelling tasks, and are...
QMCPACK, a scalable quantum Monte Carlo package (QMC), has been highly optimized for the latest high end microprocessors: arrays and loops have been restructured to get high vectorization ratios, parallelism is easily and efficiently exploited through the MC nature of the algorithm and finally a lot of attention has been paid to use highly tuned MKL libraries. Identifying optimization...
Excessive studies and simulations are required to plan for the upcoming upgrades of the world’s largest particle accelerators as well as for the design of future machines with tight budgetary margins. The Beam Longitudinal Dynamics (BLonD) simulator suite incorporates the most detailed and complex physics phenomena in the field of longitudinal beam dynamics, required for extremely accurate...
Modern computing architectures allow for unprecedented levels of parallelization,
bringing a much-needed speedup to key scientific applications, such as ever improving
numerical simulations and their post-processing, likewise increasingly taxing.
We report on optimization techniques used on popular codes for computational
astrophysics (FLASH and ECHO) and the performance gained on...
In the age of big data, increasing simulation accuracy, we often need more pixels to show the minute details that traditional single display system cannot provide. Industrial designers such as car manufacturing design teams rely on high-fidelity photorealistic rendering, as supplied by the Intel OSPray framework, to study the interaction of materials and shapes in their designs. The TCP Bridge...
Lattice QCD is a fundamental non-perturbative approach to solving the quantum chromodynamics (QCD) theory of quarks and gluons. The solution of the QCD problem is solved by a lattice gauge theory formulated on a grid or lattice of points in space and time. The calculation of SU(3) operation and D-Slash in high dimensions are typical data dense tasks. In recent years, the SIMD architecture of...
