.TH migrategroup 1 "28.02.2003" "the openMosix miggroup feature"

.SH DESCRIPTION
The migdrop feature is an additional "miggroup"-/proc entry for each process
.br 
(it was added to the openMosix kernel in version 2.4.20-openMosix-3).
.br
If a new process is created the "miggroup" proc-file contains "0". The value in this file can be easily set by user-applications like "echo" or any other programs which are using the regular open(), read() and write() functions. 
.br
The main ideas behind this new /proc-entry is that you can now group your processes by setting the same value to their "miggroup" file ( /proc/[PID]/miggroup ). Then those created process-groups can be easily managed by administration-tools and/or scripts.

- make processes join a miggroup: 
.br
[root@node1 miggroup]# joingroup 1300 1332 1364 1396 1428 1460 1 
.br
miggroup = 1
