These hidden cores are fascinating.
In the past, I was interviewing at a hardware company and one of the things they had just discovered was an "unused" and undocumented processing unit that they could run a process on to get squeeze out more compute from the cameras they used for calibration for the hardware bill of materials that they had already settled on.
- bcantrill 5y agoI know that I recommended it in the talk, but I highly recommend Timothy Roscoe's OSDI keynote[0] -- and may also be worth catching the Twitter Space we did a few weeks ago discussing it.[1] [0] https://www.youtube.com/watch?v=36myc8wQhLo https://www.youtube.com/watch?v=36myc8wQhLo [1] https://github.com/oxidecomputer/twitter-spaces/blob/master/2021_09_06.md https://github.com/oxidecomputer/twitter-spaces/blob/master/...
- RobLach 5y agoThat keynote is great. It feels like looking up and seeing the sun from the floor of a deep hole you've been too focused on digging.
- sremani 5y agoRoasting a conference in the keynote is whole another level of charisma. This talk is impressive even for non-OS people like me.
- CalChris 5y agoI liked your talk but I didn't get the connection with Wright's Law. You did a good presentation of WL but I just didn't get its connection with low latency and future hardware software co-design.
- zozbot234 5y agoI guess the connection is just that Rust is an up-and-coming language, so developing with it is going to get gradually easier and cheaper as the surrounding ecosystem grows to a larger scale.
- aidenn0 5y ago- Low latency is desirable - Transistors are getting cheaper - Therefore it is cheap to put computing closer to I/O (which reduces latency) - That computing will not have the sorts of things a general-purpose CPU has (maybe no MMU, limited RAM, perhaps it's a harvard architecture)

- zja 5y agoI discovered Oxide's youtube channel a couple weeks ago, and I've been really enjoying listening to your twitter space discussions. Thanks for all the interesting content!
- sam_bristow 5y agoOooh, thanks for pointing that out. I really enjoyed their "On the Metal" podcast while they were running it.
- aidenn0 5y agoGiven that you continuously recommend Roscoe's keynote, and you are working on a message-passing microkernel; will that microkernel support message passing between heterogenous cores with heterogenous physical address spaces?
- bcantrill 5y agoI'm not sure what you mean by "continuously", but the answer to your question is "no, it doesn't."
- dralley 5y agoHey Bryan, just curious, what are your thoughts on the tradeoffs that Zig is making compared to Rust?
