Spatially-correlated intra-die process variations result in significant core-to-core frequency variations in chip-multiprocessors. An analytical model for frequency island chip-multiprocessor throughput is introduced. The improved variability-tolerance of FI-CMPs over their globally-clocked counterparts is quantified across a range of core counts and sizes under constant die area. The benefits are highest for designs consisting of many small cores, with the throughput of a globally-clockeddoi:10.1145/1391469.1391550 dblp:conf/dac/HerbertM08 fatcat:tt6yy2ksavcj3e6h6f3zuvmhyq
