Subject: New time code miscalculates cpu usage
Date: Tue, 16 Oct 2007 15:25:25 -0500 [thread overview]
Message-ID: <20071016202525.GA11837@lixom.net> (raw)
Hi,
Not sure when this started happening, but I wanted to report it. I'll
start bisecting in a day or two if noone else has gotten around to
looking at it:
$ echo "int main(void) { while(1); }" > test.c ; gcc test.c
$ time ./a.out & sleep 2 ; killall a.out
real 0m2.008s
user 0m4.014s
sys 0m0.002s
Seen on POWER5 and PA6T, haven't tried anything else yet.
-Olof
