Jim, I'm actually not sure that time will report greater than 100% cpu
on ubuntu hardy. (really not sure, and don't have it available right
this moment to check). I would however try making a computation that
will take a little longer and use the system monitor or /proc to look
at your CPU usage rather than time. I've had good luck with GHC 6.8
using > 100% cpu, so I assume 6.10 will work much better.

Hello Jim,
Saturday, February 21, 2009, 6:17:54 PM, you wrote:
main = a `par` b `par` c `pseq` print (a + b + c)
two things: 1) that are grouping order? may be, a `par` (b `par` (c `pseq` print (a + b + c))) ?
2) i recommend you to use 2 *same* computations. otherwise, it's easily possible that one of them needs much more time that the rest
where a = ack 3 10 b = fac 42 c = fib 34
fac 0 = 1 fac n = n * fac (n-1)
ack 0 n = n+1 ack m 0 = ack (m-1) 1 ack m n = ack (m-1) (ack m (n-1))
fib 0 = 0 fib 1 = 1 fib n = fib (n-1) + fib (n-2) --------------------
Thanks,
Jim
