Sacrificing Interoperability for Information Security: Containing Data Loss and Malware Propagation
Using hardware that does not provide software and data interoperability could address security problems.
How to be a good PC member ……. not!
Here are some tips to be a good PC member.
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.

The von Neumann Bottleneck Revisited
The term “von Neumann bottleneck” was coined by John Backus in his 1978 Turing Award lecture to refer to the bus connecting the CPU to the store in von Neumann architectures. In this lecture, he argued that the bus was a bottleneck because programs execute on the CPU...
Easy Persistent Memory Performance Wins
Mainstream non-volatile main memory (NVMM) is just around the corner: Intel is opening up access to their 3DXpoint technology to a broader range of companies, and we are gradually learning more about the technology. Despite our growing understanding, the question of...
Streaming Video for The Computer Architect
Today streaming video accounts for over 70% of evening web traffic in the US. YouTube upload rates outpace not only CPU performance, but Moore’s Law itself, and reached 400 hours of video per minute in July 2015. In addition to sheer hours per minute, the videos...
Intelligent memory architecture with new memory technologies
A previous blog titled “Blurring the lines between memory and compute” by R. Das was a nice summary of the history and the recent trends on addressing the memory wall challenges with process-in-memory (PIM) ideas. This blog would like to further highlight...
A Proposal to Coordinate Reviewing Across Computer Architecture Conferences
Peer-reviewed articles in top conferences are both the result and the driving force of computer architecture research. As our community expands and the number of submissions to top conferences continues to grow, it will be imperative to improve the review process....
Speculating about speculation: on the (lack of) security guarantees of Spectre-V1 mitigations
Spectre and Meltdown opened the Pandora box of a new class of speculative execution attacks that defeat standard memory protection mechanisms. These attacks are not theoretical, they pose a real and immediate security threat, and have been reportedly exploited by...Subscribe
