Question

which technology enables a cpu core to function as two threads?
affinity
ipc
smt
elasticity

Explanation:

To determine the technology that enables a CPU core to function as two threads, we analyze each option:

• Affinity: Relates to binding a process to specific CPU cores, not about a core acting as multiple threads.
• IPC (Instructions Per Cycle): Measures CPU performance, not about thread virtualization per core.
• SMT (Simultaneous Multi - Threading): This technology allows a single CPU core to execute multiple threads simultaneously, effectively making a core function as if it has two (or more) threads.
• Elasticity: Related to resource scaling in cloud - like environments, not CPU core thread functionality.

Answer:

C. SMT
