703.0. "DIGITAL UNIX - negative CPU UTIL ????" by TAV02::ZVI_P (Here we are) Wed May 07 1997 07:27

Hi

 I am doing a small UNIX study here at office before proposing a CP study
to a UNIX customer.

I collected data by DECPS and integrated it on the measured machine.

I copied the MERG file to a VMS machine and started the CP study.

For workload classes I used the DIGITAL UNIX DEFAULTS.
CP version is T4.0 .

On validation I got:

    Can someone help me resolve that ?


  It says the measured CPU utilization is -36.502 ?????

  I post the MERG file at :

$  dir ppantr::$2$DKB200:[IPMT.CP]/sec

    Hi,
    
    	I've looked into your problem. I'm also getting the utilization a
    negetive value. Can you provide me with :
    	1. .proc file generated along with the .merg file and
    	2. .cpd file used to generate the .merg file.
    
    
    	We've fixed the spec numbers in ecp_axpvmscpu.dba. Plesae copy the
    file from cpdev::public:[anonymous].
