The system performs this calculation. Are you sure you want to do it yourself? >Our machine has 5 engines.

The latest information is at https://www-304.ibm.com/servers/resourcelink/lib03060.nsf/pages/srmindex?OpenDocument . If you are using advertised MSU to compute SU/second, you will not get good results. I don't remember which control block contains the CPU/second value that SRM uses. Also beware that if you make dynamic changes for the processor, such as with capacity on demand, the SU/second value will change. SRM is aware and its calculations of SU usage are adjusted accordingly. -- Tom Marchant ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
