How can I avoid core files if my program crashes#
Core files can be very helpful when debugging a problem but they also take a long time to get written for large parallel programs. The following command will limit the core size to zero, i.e. no core files will be written:
ulimit -c 0 # for bash/ksh
limit stacksize 0 #for tcsh/csh
The effect of the above command call can be checked with:
ulimit -c # for bash/ksh
limit stacksize #for tcsh/csh
Please, note that the command name and syntax are specific to a shell used.
