Comment	> When I test GNU Parallel I use redhat as the central node. From there > I ssh in parallel to all the other systems. > > But because the limit of processes and open files is very low (100 > and 200) I can only run very few jobs in parallel. > > It is fine to keep the soft limit where it is, but it would be nice > if the hard limit was much higher. So that you can raise the limit if > you know what you are doing. > > On most of my systems I have 1M file handles, and I do not experience > any performance or memory issues due to this. > > So the adjustment is for nofile and noproc in /etc/security/limits.conf > > These seem OK: /proc/sys/fs/file-max /proc/sys/kernel/pid_max >
