Forty-five years ago this month, Intel co-founder Gordon Moore predicted that the number of transistors on an integrated circuit would double each year (later revised to every 18 months). This laid the groundwork for another prediction: that doubling the number of transistors would also double the performance of CPUs every 18 months.

This bold prediction, known as Moore’s Law, long held true. But we have reached the limit of what is possible with one or more traditional CPUs. The computing industry – and everyone who relies on it for continued improvements in productivity – needs to take the leap into parallel processing. has published a piece I’ve written about this, describing how the CPU scaling predicted by Moore’s Law is now dead. Give it a read here, and feel free to post comments in this blog.
