Hello, For a new project I need to implement a mechanism that will allow me to gather process together according to a user choice. For example, here is a list of running process: USER ID COMMAND thouveng 345 gnome-session thouveng 348 /usr/bin/ssh-agent /usr/share/apps/switchdesk/Xclients.gnome thouveng 413 /usr/libexec/gconfd-2 11 thouveng 456 /usr/libexec/bonobo-activation-server --ac-activate thouveng 467 metacity --sm-save-file 1080547315-1211-2058173655.ms thouveng 556 gnome-settings-daemon --oaf-ior-fd=14 thouveng 560 xscreensaver -nosplash I want to be able to group together process with ID 467 and 560 in order to study how those processes use resources on the system. So, an idea is to add a new structure to store them and a new module to manipulate those new "container". Before do it myself, I'd like to know if this already exist. I do web search and I find the PAGG (Process Aggregate) project which is very close to what I need. I tried it but when I booted the new kernel, the memory usage was always above 40%... I don't know if it's because of the patch (which is dated from nov 7 2002) but this strange behavior pushed me to look for other solutions.
