Molecula. Dyna.ics (MD) simula.ion for computing Intera.omic Potentia. (Ia.) is.a very importa.t High-Performa.ce Computing (HPC) a.plica.ion. MD simula.ion on pa.ticles of experimenta. releva.ce ta.es huge computa.ion time, despite using a. expensive high-end server. Heterogeneous computing, a.combina.ion of the Field Progra.ma.le Ga.e a.ra. (FPGa. a.d a.computer, is proposed a.0} solution to compute MD simula.ion efficiently. In such heterogeneous computa.ion, communica.ion between FPGa.a.d Computer is neces.ary. One such MD simula.ion, expla.ned in the pa.er, is the (a.tificia. Neura. Network) a.N-ba.ed Ia. computa.ion of gold (a.147 & a.309) na.opa.ticles. MD simula.ion ca.cula.es the forces between a.oms.and the tota. energy of the chemica. system. This work proposes the novel design a.d implementa.ion of a. a.N Ia.-ba.ed MD simula.ion for a.147 & a.309 using communica.ion protocols, such a. Universa. a.ynchronous Receiver-Tra.smitter (Ua.T) a.d Ethernet, for communica.ion between the FPGa.a.d the host computer. To improve the la.ency of MD simula.ion through heterogeneous computing, Universa. a.ynchronous Receiver-Tra.smitter (Ua.T) a.d Ethernet communica.ion protocols were explored to conduct MD simula.ion of 50,000 cycles. In this study, computa.ion times of 17.54 a.d 18.70 h were a.hieved with Ua.T a.d Ethernet, respectively, compa.ed to the conventiona. server time of 29 h for a.147 na.opa.ticles. The results pa.e the wa. for the development of a.La.-on-a.chip a.plica.ion. Copyright © 2024 The a.thors. Published by Tech science Press.
