IBM Power 770 and 780 (9117-MMD, 9179-MHD) Technical Overview and Introduction

2.1.3 Simultaneous multithreading

processors support SMT1, SMT2, and SMT4 modes to enable up to four
instruction threads to execute simultaneously in each processor core. The
processor supports the following instruction thread execution modes:

򐂰

SMT1: Single instruction execution thread per core

򐂰

SMT2: Two instruction execution threads per core

򐂰

SMT4: Four instruction execution threads per core

SMT4 mode enables the processor to maximize the throughput of the processor
core by offering an increase in processor-core efficiency. SMT4 mode is the latest step in an
evolution of multithreading technologies introduced by IBM. Figure 2-3 shows the evolution of
simultaneous multithreading in the industry.

Figure 2-3 Evolution of simultaneous multithreading

The various SMT modes offered by the processor allow flexibility, enabling users
to select the threading technology that meets an aggregation of objectives such as
performance, throughput, energy use, and workload enablement.

Intelligent Threads

The processor features Intelligent Threads that can vary based on the workload
demand. The system either automatically selects (or the system administrator can manually
select) whether a workload benefits from dedicating as much capability as possible to a
single thread of work, or if the workload benefits more from having capability spread across
two or four threads of work. With more threads, the processor can deliver more
total capacity as more tasks are accomplished in parallel. With fewer threads, those
workloads that need fast individual tasks can get the performance that they need for
maximum benefit.
