[PerfSuite-users] CPU time greater than Wall clock time

[Naveen P. <nav...@gm...>]

Dear Perfsuite users,

I'm a new user of Persuite/PAPI and would appreciate comments on my query
below.

On a quad core intel runing Fedora Core 6 (kernel 2.6.18), I get the
following numbers while runing a *single* threaded program:
CPU time (seconds)          47.966
Wall clock time (seconds) 30.582

Since the CPU time > Wall clock time, one conclusion might me a bug in
Perfsuite/PAPI or somewhere else.  I double checked the CPU
time by dividing PAPI_TOT_CYC count by CPU frequency, and I arrive at the
same number. Any ideas on what might be going on or what might be the best
approach to debugging this problem is appreciated.

Thanks,
-Naveen
