IBM z Systems: Performance Report on Exploiting SMT for SAP Application Servers on z13

An IBM Redpaper publication



Abstract

With the recent availability of the IBM z13™ machine, the new processor chip offers intelligently implemented 2-way simultaneous multithreading. Simultaneous multithreading (SMT) allows two active instruction streams per core, each dynamically sharing the core's execution resources. The SMT feature is available in IBM® z13 for workloads running on the Integrated Facility for Linux (IFL) and the z Integrated Information Processor (zIIP).

SAP on IBM z Systems™ is an excellent candidate in employing zIIP processors for the SAP database server, and IFL processors for SAP application servers. Therefore, it can exploit SMT and potentially see performance gains from using it.

This IBM Redpaper™ publication documents our tests and findings. The measurements were stress tests, not certified benchmarks.
