Can Broken Multicore Hardware be Mended?
The multi- and many-core (MC) era we have reached was triggered after the beginning of the century by the stalling of single-processor performance. Technology allowed more transistors to be placed on a die, but they could not reasonably be utilized to increase single-processor performance. Predictions about the number of cores has only partly been fulfilled: todayΓ’β¬β’s processors have dozens rather than the predicted hundreds of cores (although the Chinese supercomputer [3] announced in the middle of 2016 comprises 260 cores on a die). Despite this, the big players are optimistic. They expect that Moore-law persists, though based on presently unknown technologies. The effect of the stalled clock frequency is mitigated, and it is even predicted [6] that Γ’β¬ΒNow that there are multicore processors, there is no reason why computers shouldnΓ’β¬β’t begin to work faster, whether due to higher frequency or because of parallel task execution. And with parallel task execution it provides even greater functionality and flexibility! Γ’β¬Β
