  • SCALING of the LAMMPS code on NVIDIA A100 GPU cards

    SCALING of the LAMMPS code on NVIDIA A100 GPU cards

    Note (GPU cards are the same type as on Karolina supercomputer at IT4Innovations) The advance of computing power has opened new perspectives of computational materials design. Accurate predictions of the intrinsic physical properties are routinely obtained by performing ab-initio simulations at the atomistic level. These calculations, however, have severe restrictions on the size and temporal evolution of the systems. Finite-temperature properties of nano- and meso-scale systems (104 to 107 atoms) are simulated via classical Molecular... Read More

  • Scaling of VASP 5 on IT4Innovations clusters – metallic structure

    Scaling of VASP 5 on IT4Innovations clusters – metallic structure

    We wanted to see how well does VASP 5.4.4 scales on CPU Nodes at Salomon and Barbora supercomputers at IT4Innovations National supercomputing center in Ostrava, Czech republic. Those clusters in question are both x86, Intel-based CPU clusters. Though Barbora has 8 nodes with 4x Tesla V100 each, those will not be a subject of this test. Salomon has 24 cores per node in two sockets, Barbora has 36 nodes per node in the same configuration.... Read More
