Diverging Chip Architectures in the Wake of Spectre and Meltdown

In this podcast, the Radio Free HPC team looks at the tradeoff between chip performance and security. In the aftermath of the recently disclosed Spectre and Meltdown exploits, Cryptograpy guru Paul Kocher from Rambus is calling for a divergence in processor architectures:

The direction that we need to go as an industry though is ...We need to stop trying to build one processor architecture that is great for playing video games and doing wire transfers. We need to build architectures where there are cores and software stacks designed for security that can be slower, that can be simpler, and we need separate ones that are optimized for performance."

In this video, Paul Kocher presents: Spectre - Exploiting Speculative Execution. Kocher is the lead author of the paper on the Spectre processor vulnerability.

After that, we do our Catch of the Week.
