The Increasing Heterogeneity of Cloud Hardware and What It Means for Systems

Dominoes

The past five years have seen a significant change in the way cloud servers look. Traditionally homogeneous cloud systems are progressively shifting to heterogeneous designs, either through special purpose chips, like Google’s TPUs, or reconfigurable fabrics, like Microsoft’s Catapult and Brainwave projects; sometimes, they even adopt a combination of the two. This post provides an … Read more The Increasing Heterogeneity of Cloud Hardware and What It Means for Systems

ASPLOS 2020 Online Conference Experience

With little more than two weeks to go, the ASPLOS 2020 General chair and steering committee decided they could not go forward with the planned physical event 16-20 Mars in Lausanne, Switzerland due to the ongoing COVID 19 pandemic. With a record-sized program of 86 papers and 400-500 expected attendance, simply canceling the event was … Read more ASPLOS 2020 Online Conference Experience

The Remarkable Utility of Dataflow Computing

Dataflow graph

We build computer systems around abstractions. The right abstractions are timeless and versatile, meaning they apply in many different settings. Such abstractions make developers’ lives easier, and allow system developers and researchers to optimize performance “below the hood”, by changing systems without breaking the abstractions. In this post, I will argue that the abstraction of … Read more The Remarkable Utility of Dataflow Computing
