output log

Description of problem:  Seeing random failures with Interlagos cpuscaling testing.  Very difficult to get a passing run.  


Version-Release number of selected component (if applicable): RH 6.1 x64 GA / v7-1-3-46


How reproducible: 90+ percent of time


Steps to Reproduce:
1.  DL585 G7.  (4) 2.6 Interlagos.  
2.  Install RH 6.1 x64 and v7-1-3-46
3.  execute cpuscaling
  
Actual results:
Intermittent random error with current processor speed setting causes test to fail.  All actual workload results are successful.

Expected results:

If workload results are successful, overall test should pass.

The error seen in the log is:

Error: cpu36 in package 0 has the value 2600000 which differs from other cpus in the package.

process for cpu 24 is done in 44.54 seconds
process for cpu 12 is done in 44.89 seconds
process for cpu 20 is done in 44.66 seconds
process for cpu 48 is done in 44.85 seconds
process for cpu 16 is done in 44.55 seconds
process for cpu 32 is done in 44.64 seconds
process for cpu 44 is done in 44.41 seconds
process for cpu 56 is done in 44.72 seconds
process for cpu 28 is done in 44.56 seconds
process for cpu 36 is done in 44.63 seconds (not running at 2600000 since workload is taking the same as the other processors)
process for cpu 40 is done in 44.45 seconds
process for cpu 52 is done in 44.57 seconds
process for cpu 60 is done in 44.71 seconds
process for cpu 0 is done in 44.81 seconds
process for cpu 4 is done in 44.61 seconds
process for cpu 8 is done in 44.54 seconds

And 

Error: cpu34 in package 2 has the value 2600000 which differs from other cpus in the package

process for cpu 34 is done in 24.09 seconds (again running the workload at the same speed as the other processors that didn't report an error.)

Results with interlagos performance boost disabled in rbsu.

With AMD Core Performance Boost disabled in bios, I was able to pass the test 3 out of 3 times.

Comment 4 Gregg Shick 2011-07-20 18:30:22 UTC
Although it still has one of these failures in the log:  

Error: cpu36 in package 0 has the value 2600000 which differs from other cpus
in the package.
