This stuff dates way, way before 2004. For non-power of two, just checked our own very old circular byte buffer library code and using the notation from this article, it is: entrie…

So after transforming multispectral satellite data into a 128-dimensional embedding vector you can play "Where's Wally" to pinpoint blackberry bushes? I hope they tasted good! I'm …

We ended up overriding and replacing with our own thread-safe version years ago when we also hit this.

Good to see you too! Lets catchup sometime - tried to connect with you separately but no luck.

Founder of cunoFS here, brilliant to see lots of activity in this space, and congrats on the launch! As you'll know, there's a whole galaxy of design decisions when building file s…

Dynasaur intercepts syscalls in Linux entirely in userspace, superfast and across static, semi-static and dynamic binaries. It even works inside containers and doesn't need admin o…

Yes Bali was the next gen architecture and incredibly scalable. It consisted of many different chips connected together in a network that could scale. The R chip was so big existin…

Nintendo wasn't loyal to the company it was loyal to the team, so when they just decided to leave and form ArtX they took the customer with them... SGI was happy with the Nintendo …

I worked at SGI on the next generation (code named Bali) in 1998 (whole year as an intern) and 1999 (part time while finishing my degree, flying back and forth from Australia). Bal…

Sorry for the late response - I didn't see your comment until now. Our aim is to unleash all the potential that S3/Object has to offer for file system workloads. Yes, the scale of …

The problem with these approaches is that the data is scrambled on the backend, so you can't access the files directly from S3 anymore. Instead you need an S3 gateway to convert fr…

IOPS is a really lazy benchmark that we believe can greatly diverge from most real life workloads, except for truly random I/O in applications such as databases. For example, in Ma…

It depends on if you want to expose filesystem semantics or metadata to applications using it. For example random access writes are done by ffmpeg, which is a workhorse of the medi…

For example, you can do separate parallel ListObjectV2 for files starting a-f and g-k, etc.. covering the whole key space. You can parallelize recursively based on what is found in…

For AWS, we're comparing against filesystems in the datacenter - so EBS, EFS and FSx Lustre. Compared to these, you can see in the graphs where S3 is much faster for workloads with…

Actually we've found it's often much worse than that. Code written against AWS S3 using the AWS SDK often doesn't work on a great many "S3-compatible" vendors (including on-prem ve…

We and our customers use S3 as a POSIX filesystem, and we generally find it faster than a local filesystem for many benchmarks. For listing directories we find it faster than Lustr…

We've spent a lot of time identifying bottlenecks and fixing them, up and down the stack, with FUSE being just one of them, even the AWS SDK itself introduces its own set that we'v…

Hello HN! We’re Dan and Vaughan, based in Cambridge, UK. We recently launched cunoFS, a filesystem for fast, POSIX object storage access. Yes, we’ve heard that “Object Storage is j…

This is a nice simple visual guide to chip fabrication, chiplets, and the advantage of back-side power.

Funnily enough I published something similar as part of my PhD (2010). Essentially communication costs dominate over computation costs - an addition operation is practically free c…

Hi sorry I missed this. Yes, you can run Samba for SMB, and Ganesha for NFSv4. Feel free to email us if you think there's a better way though.
