Crazy forever
In a computer with 8 cores (2 quad core CPU, no HT) I run 6 physics simulation programs. The system gave me a 40% idle report in top (not very accurate).
Cpu(s): 59.0% us, 0.2% sy, 0.0% ni, 40.2% id, 0.5% wa, 0.0% hi, 0.0% si
Then I tried to overload the system with more simulation programs. I run another 4. Now the system is overloaded with tasks, but top command still returns 40% idle.
What's the problem with top? Did it update after a minute?
Edit: waited for several minutes, still 59.0% us
is it frozen?
