Should you enable Simultaneous Multithreading (SMT) on your z13, z13s, or z14 for your zIIP workloads? That is an interesting question that doesn’t have an easy answer. If you do enable SMT, you should be prepared to review a number of SMT-specific measurements, as well as your standard application measurements. Unfortunately, these are some of the most confusing, misunderstood, and poorly documented measurements in all of the SMF data.
Join Scott Chapman in this session as he explores the meaning and derivations of the SMT measurements and then presents existing measurements that may be useful in determining if SMT should even be explored. A decision tree for deciding whether to stay in single-threaded mode or try SMT-2 will be introduced.
