Aquila: A unified, low-latency fabric for datacenter networks
- learndeeply 4y ago(not a hardware engineer) This looks like Google's version of Infiniband, which is basically mandatory for large scale ML-training servers due to issues with Ethernet, as described in the paper. Really cool stuff, wonder if we'll see traditional network hardware manufacturers copying this design.
- trishume 4y agoThe latency numbers they state seem achievable or beatable with Infiniband, Amazon's EFA, or TCPDirect. 2us round-trip is achievable for very simple systems. If this kind of networking sounds good to you, you can buy it today! It's even available on AWS, Azure and Oracle Cloud (but not GCP yet AFAIK).
- wumpus 4y agoLatency measurements are tricky, the usual benchmarks kind of suck and aren't predictive of actual performance in real systems under load. Given that the entire Myrinet team went to work for Google, and the InfiniPath microarchitecture can be discovered by reading the device driver and some open source code, I'm pretty sure Google's team was well aware of what has been done in the recent past.
- wumpus 4y agoThank you upvoters! I wonder why my other comment has so many downvotes, when it's just as relevant as this one.
- stevekemp 4y agoOff-topic, but that's an awesome name. I remember the Aquila TV series, in the UK, fondly. Enough that I tracked down the books to read.
- gbrown_ 4y agoYou could have some serious fun with a battle cruiser! It’s bizarre how much I remember of that show, none of the Latin though.
- simonebrunozzi 4y agoAquila means "eagle" in Italian. There's also a city with the name Aquila, or "L'Aquila", where L' equates to "the", in the Abruzzo region. [0] [0]: https://en.wikipedia.org/wiki/L%27Aquila https://en.wikipedia.org/wiki/L%27Aquila
- nuccy 4y agoThere was/is also a BBC TV show from late 90s about a "spacecraft" of the same name[1]. 1. https://en.wikipedia.org/wiki/Aquila_(TV_series) https://en.wikipedia.org/wiki/Aquila_(TV_series)
- wizzzzzy 4y agoSame! Weirdly remember this programme more than most. The episode where it stops working until the dad cleans it specifically!
