Dynamic graph random walk (DGRW) emerges as a practical tool for capturing structural relations within graph. Effectively executing DGRW on GPU presents certain challenges. First, existing sampling methods demand pre-processing buffer, causing substantial space complexity. Moreover, the power-law distribution of vertex degrees introduces workload imbalance issues, rendering embarrassed to parallelize. In this paper, we propose FlowWalker, GPU-based dynamic framework. FlowWalker implements an...

We present a machine learning (ML) framework for large-scale dynamical simulations of charge density wave (CDW) states. The modulation in CDW state is often accompanied by concomitant structural distortion, and the adiabatic evolution order governed dynamics lattice distortion. Calculation electronic contribution to driving forces large systems, however, computationally very expensive. Assuming principle locality electron neural-network model developed accurately efficiently predict local...

We report on a theoretical study of the $\pi^- p \to a^-_1(1260) p$ and \pi^- \rho^0 reactions near threshold within an effective Lagrangian approach. The production process is described by $t$-channel $\rho^0$ meson exchange. For reaction, final \rho^0$ results from decay $a_1(1260)$ resonance which assumed as dynamically generated state $K^* \bar K$ $\rho \pi$ coupled channel interactions. calculate total cross section reaction. It shown that, with coupling constant to obtained chiral...

We present a scalable machine learning (ML) force-field model for the adiabatic dynamics of cooperative Jahn-Teller (JT) systems. Large scale dynamical simulations JT also shed light on orbital ordering in colossal magnetoresistance manganites. The effect these materials describes distortion local oxygen octahedra driven by coupling to degrees freedom $e_g$ electrons. An effective electron-mediated interaction between modes leads structural transition and emergence long-range order at low...

One of the major challenges to design a high performance computer system is predict accurate interchip timing as well control electrical noises such crosstalk, reflections and Ldi/dt noise. As board level clock frequency exceeds 50 MHz, using conventional full swing CMOS driver driving heavily loaded long bus on PCB or backplane obtaining desirable result becomes increasingly difficult. In order achieve higher with bus, low voltage 800 mV transmission line transceiver (Gunning et al., 1992),...
