Dear Prof. Case,
Thank you. I solved this problem, as polyAT_wat_min2.rst was missing in the old directory. I redo the calculations again. This time the jobs start without problem. However, the works seems to stop at the location:
--------------------------------------------------------------------------------
3. ATOMIC COORDINATES AND VELOCITIES
--------------------------------------------------------------------------------
begin time read from input coords = 0.000 ps
Number of triangulated 3-point waters found: 2968
--------------------------------------------------------------------------------------------------
I tried to do the calculations with single node, the jobs finished without an error. How can I double check if the jobs are visible to all the nodes?
Best regards & thanks,
