Engine-ering


Presentation

Traditionally people work on CPU at the LPAR level. However, there is considerable value in going down to the logical processor (or engine) level.

For example, HiperDispatch behaviour is much more understandable if you consider individual engine behaviour. Relative system performance is also more explicable if you go down to the engine level.

This presentation, with examples, gives a structured approach to realising the value from going top down to individual engines.

Speakers


  • Martin Packer at IBM UK LTD.
  • With 32 years of mainframe experience (about 40 of computers), Martin is widely known within the industry, having presented at many conferences and having authored a number of IBM Red Books on performance and other matters. He continues to develop System Analysis tools he uses every day in some of the most difficult Performance and related mainframe situations IBM customers encounter: He has a very wide range of experience of what enterprises do with their System z mainframes. Getting "low down and dirty" with instrumentation gives him a rare insight into what the data can do: He leads others - customers, IBMers, business partners, and other vendors - in getting the value out of this instrumentation. With that experience base he drives conversations with developers about enhancing instrumentation, as well as their products in general. But it's not all about the mainframe: He has a wide range of other technological interests. For example, he knows a lot about programming and how the web is constructed. Last year he started the Mainframe, Performance, Topics Podcast series with Marna Walle.
