one-core: Most modern CPUs are SMP (multicore). However, when only one core is present, some aspects of coherence are much cheaper. For example, RISC-V can use one instruction fence.i rather than a syscall that invokes all other cores. This feature enables such optimizations, but the resulting program will only be safe to run on one-core systems.
