a process in a strange state

[Jacques Beigbeder]

Hello,

Hardware: bi-pro. Intel Xeon E5520, so /proc/cpuinfo display 16 processors.
OS: Ubuntu 10.04.1 LTS
Usage of this computer: lot of long computations

top displays:
	top - 13:26:09 up 29 days,  2:10,  5 users,  load average: 9.15, 9.12, 9.09
	Tasks: 352 total,  10 running, 341 sleeping,   0 stopped,   1 zombie
	Cpu(s): 75.7%us,  2.7%sy,  0.0%ni, 21.6%id,  0.0%wa,  0.0%hi,  0.0%si,  0.0%st
	Mem:  74372776k total, 29699520k used, 44673256k free,   248240k buffers
	Swap: 134223032k total,     5408k used, 134217624k free,   929532k cached

so it has an uptime of 9. But only 8 processes displays %CPU near 100%.

ps augxww | grep 11011 displays:
	USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
	xxxxxxx  11011 320096871  4.0 3022636 3007260 ? R<  Mar09 17179869:11 ./someprog

So for process 11011:
	%CPU = 320096871
	%MEM = 4.0
	VSZ = 3022636
	RSS = 3007260
	TTY = ?
	STAT = R
	START = Mar09
	TIME = 17179869:11, TIME?
strace -p 11011 has nothing to display.

May I assume that process 11011 runs, since uptime is 9?
What is this strange %CPU??

Thanks for your help,
