TPF CPU Measurement report for our clients

This request is for IBM to provide HP with the ability to provide CPU measurement reporting for TPF systems running for one of our clients. The data will help both provider and customer manage the CPU performance of the TPF applications and systems. The team had discussed this one with IBM and per IBM the current function is not intended to be used as our client requested, so they suggested we open an RFE.

    The instrumentation which is being requested is based upon the counter data. TPF has a spin loop in dedicated environments which causes the counter data to be seriously biased/useless. In order to obtain relevant performance information the data from Diagnostic Sampling must be gathered.

    Interpretation of CPUMF data for performance estimation/projection requires significant knowledge of IBM machine design and implementation to understand how the processor handles the characteristics of the customers unique workload. To this end TPF customers will be best served by doing full CPUMF with diagnostic sampling turned on and sending these results to the TPF lab. We recommend CPUMF runs about once per year and when significant HW/SW changes are made. e.g. migration from EC12 to z13, with large TPF application changes, or when there are large unexplained changes in the mils per message.

    The lab will supply summary data for each customer that does a CPUMF data run which will include: MIPS, L1 to L4 cache, TLB etc. This supplied data will always be valid. We will also archive this data to aid in our ability to project future processor requirements.
