Computer Architecture Today

Informing the broad computing community about current activities, advances and future directions in computer architecture.
Reflections on trusting SGX

Reflections on trusting SGX

The security community will remember the year of 2018 as the year of speculative execution attacks.  Meltdown and Spectre, the recent Foreshadow (L1TF in Intel’s terminology), and their variants demonstrate how the immense processor design complexity, perpetual...

Data management on non-volatile memory

Data management on non-volatile memory

In a recent blog post, Steve Swanson presented three milestones that mark the adoption path of non-volatile memory by applications. The next step in this path is tailoring fundamental protocols and algorithms for non-volatile memory. We illustrate this point using...

Server Architecture for the New Age Datacenter

Server Architecture for the New Age Datacenter

Server architectures have largely been boring. Boring has been good. It has helped applications thrive in a stable H/W ecosystem and innovate at providing business logic. While performance improvements have largely been single thread performance improvements extended to data center class systems, we are beginning to see a new era in Server architecture designs driven by memory technologies, accelerators and fabrics like Gen-Z, CCIX and Open CAPI that glue them.
