CaSA – Observations from Uppsala

“Unusual Perspectives on AI” – Computer and System Architecture Unraveled Event Five

The fifth CaSA, Computer and System Architecture Unraveled, meetup took place on January 30. We finally gave in and joined the AI hype train, resulting in an event with a somewhat different audience and different discussions. More society and applications, less computer architecture. Our two presenters were Håkan Zeffer from SambaNova Systems and Björn Forsberg from RI.SE (doing his second CaSA presentation!). Håkan talked about the architecture of the Sambanova AI processors, and Björn about AI compilers.

“Processor Performance Insights and Optimization” – Computer and System Architecture Unraveled Event Four

Finally, the fourth CaSA, Computer and System Architecture Unraveled, meetup happened on November 6. It took far too long to get it organized, but we finally did it. The theme was about processor performance analysis and efficient processor implementation, offering two talks from very different perspectives. The location was almost the same as before, on the 19^th floor of the Kista Science Tower building. Once more thanks to the sponsorship from Vasakronan and Kista Science City.

“RISC-V in Practice” – Computer and System Architecture Unraveled Event Three

On Wednesday, March 13, we had our third CaSA, Computer and System Architecture Unraveled, meetup. Same place as the previous, the 25^th floor of the Kista Science Tower building, thanks to the kind sponsorship of Vasakronan and our collaboration with Kista Science City. The theme this time was “The RISC-V ISA in Practice”, with two speakers named Björn. Another great event!

“Packet Networks are not Socket Science” – Computer and System Architecture Unraveled Event Two

On Wednesday, November 22, we had our second CaSA, Computer and System Architecture Unraveled, meetup. Same place in Kista as the last time, the 25^th floor of the Kista Science Tower building, thanks to the kind sponsorship of Vasakronan and our collaboration with Kista Science City. This time, the theme was networking – but not at the socket level. Per Holmberg presented how his team used “micro sleep” for power management in line-rate network processing, and Hans Brandberg talked about the Precision Time Protocol. Another great event!

The first Computer and System Architecture Unraveled Event in Kista – Great Speakers, Great Fun!

On the evening of the last Wednesday in September, we had our first CaSA, Computer and System Architecture Unraveled, event. CaSA is a meetup in Kista (Sweden) for people interested in computer architecture, system architecture, and how software and hardware interact down towards the lower levels of the stack. The topic for the inaugural event was “Core Count Explosion: A Challenge for Hardware and Software”, and it was great in some many ways!
