Respected Lammps users, I am using lammps 15 July 2023 and march 2023 widowns version mpi, After installation of march 2023 version doesnt contain lm_mpi.exe file in bin after which I downloaded july 2023. I need to use mpi run as it works for few hours then suddenly shutdown showing an error. Kindly assist to resolve it. In addition is it better to use OMP multithreded run rather than to use mpi as I used both of these together worked but the speed was not so fast as mpi alone? Below are the specs of computer. Thanks
