Hi users, Am running the mdrun_mpi on cluster with the md.mdp parameters as-
; VARIOUS PREPROCESSING OPTIONS title = Position Restrained Molecular Dynamics ; RUN CONTROL PARAMETERS constraints = all-bonds integrator = md dt = 0.002 ; 2fs ! nsteps = 2500000 ; total 5000 ps. nstcomm = 10 nstxout = 500 ; collect data every 1 ps nstxtcout = 500 nstvout = 0 nstfout = 0 nstlist = 10 ns_type = grid rlist = 1.0 coulombtype = PME rcoulomb = 1.0 vdwtype = cut-off rvdw = 1.4 pme_order = 4 ewald_rtol = 1e-5 optimize_fft = yes DispCorr = no ; Berendsen temperature coupling is on Tcoupl = v-rescale tau_t = 0.1 0.1 tc-grps = protein non-protein ref_t = 300 300 ; Pressure coupling is on Pcoupl = parrinello-rahman Pcoupltype = isotropic tau_p = 1.0 compressibility = 4.5e-5 ref_p = 1.0 ; Generate velocites is on at 300 K. gen_vel = yes gen_temp = 300.0 gen_seed = -1 The grompp runs fine. but when i run the mdrun_mpi i get an error such as- Child exited abnormally! Killing remote processes...DONE Aiswarya
