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