Multithreading (MT) is a new function that is provided for z/OS
to use a core more efficiently when it encounters cache misses. Multithreading
allows multiple threads to dispatch a work unit simultaneously to
the same core. Multithreading improves the probability that at least
one thread has an instruction ready to run (not resolving a cache
miss), which increases core throughput.
When change was introduced
V2R1 (as updated February 2015).
