Hi, this looks like a problem with the MPI and/or UCX library. Try running somr test job only with orca using more than 1 cpu if that works.
Best,
Martin

[EXTERNAL EMAIL]
Hi everyone,
I have a question about using QM with ORCA as the external program for AMBER. When I perform this calculation in serial, it works fine, however, when using parallel it fails after a couple of steps. Does anyone have experience with this?
Here is my mdin file:
&cntrl
imin = 0, ! Perform MD, not minimization
irest = 1, ! Restart simulation from previous run
ntx = 5, ! Coordinates and velocities from the restart file
nstlim =100, ! Number of MD steps = 1 ps
dt = 0.0005, ! Time step in picoseconds
cut = 8.0, ! Non-bonded cutoff in angstroms
ntr = 0, ! No positional restraints
restraint_wt = 0.0, ! Weight of restraint (no restraints applied)
ntb = 2, ! Constant pressure periodic boundary conditions
ntp = 1, ! Isotropic position scaling (NPT ensemble)
barostat = 1, ! Berendsen pressure control
ntc = 2, ! SHAKE on bonds involving hydrogen
ntf = 2, ! Bond interactions with hydrogens excluded
ntt = 3, ! Langevin thermostat
gamma_ln = 5.0, ! Collision frequency for Langevin dynamics
tempi = 310, ! Initial temperature
temp0 = 310, ! Target temperature
ioutfm = 1, ! Write binary trajectory file
ntpr = 1, ! Print energy information every 500 steps
ntwx = 1, ! Write coordinates to trajectory file every 500 steps
ntwr = 1, ! Write restart file every 500 steps
ifqnt=1, ! Turn on QM/MM

.... aborting the run
Am I not allocating enough memory? According to the job file, it uses about 200-300 mb per step and if maxcore is mb allocated per cpu (ntasks is 8 and cpus per task is 1 so 8 total) then I figured it would be enough if my maxcore is 2000.
