db2 9 processes on linux.

I logon the OS use instance owner db2inst1 and enter ps -al, the
output is:
F S UID PID PPID C PRI NI ADDR SZ WCHAN TTY TIME CMD
0 S 509 12434 1 0 76 0 - 13450 pipe_w pts/0 00:00:00
db2bp
4 S 0 14704 1 7 83 0 - 39983 - pts/0 00:00:00
db2sysc

db2fmp
0 R 509 14720 12319 0 77 0 - 1069 - pts/0 00:00:00 ps

This is a new installed partitioned instance, and have not created any
database, why there are so many db2sysc processes?
I also try to create a non partitioned instance, using the same
command, and I got about 3 db2sysc processes.
What are these processes used for, db2bp, db2sysc, db2fmp, etc.
