calibration test(?) error

calibration test(?) error

Postby cyptic » Sun Nov 06, 2011 12:36 pm

Hi,
I have been exploring performance counters and I am new to the whole concept of hardware performance counters. I was exploring PAPI 4.2 and found that a test failed.

The test passes sometimes and fails irregularly.

Here is the output of a failure instance:
