sysadmins often say this, so they don't have to check it out, or when they don't know what they are doing. if they *know* that there is something wrong with the input, then they should at the very least tell you what it is. but i agree that if it works with less processors, it should work with more. unless you are using some very unusual settings when launching the job. more likely is that you are running out of memory on the machine or are hitting a stack size limit or something similar. your system manager(s) should be able to figure this out and/or advise you how to run that you are using less memory, or with a hybrid MPI plus OpenMP parallelization or whatever else is possible on the specific machine. in any case, it doesn't really sound like a QE problem. axel. > Sorry if I am asking stupid doubts but I am little new at this. > Vishal Gupta > B.Tech. 3rd year Mechanical > Indian Institute of Technology Ropar > Rupnagar (140001), Punjab, India. > Email :- [email protected] > > On Fri, Aug 14, 2015 at 10:32 PM, Axel Kohlmeyer <[email protected]> wrote: >> >> On Fri, Aug 14, 2015 at 12:58 PM, Vishal Gupta >> <[email protected]> wrote: >> > I've been running an SCF calculation for a fee Ni system on High >> > performance >> > cluster.
