Simultaneous multithreading (SMT) technology, available on the IBM z13 and later, offers intelligently implemented two-way simultaneous multithreading.
SMT allows two active instruction streams per core, each dynamically sharing the core's execution resources.
Does CA-IDMS support SMT?
CA-IDMS, all available releases.
CA-IDMS is unaware of the Simultaneous multithreading support, but runs successfully in such environments.
There are no known problems.
