This is the trouble with submitting to OS conferences. Their networking knowledge is typically limited. I’ve seen the same thing happen in the past.

FWIW - I don't think it would be that hard to port VMA or ExaSOCK to run on top of DPDK, certainly less effort than making a whole new category of operating system! But ... selling the hardware is where those companies make their money

Fair enough. My guess is that the commercial solutions are simply going where the money is. If there was a commercially pressing need to port to other systems, I’m sure it can be done. With that said, it's one thing to have a legitimat

Yet another academic work in the OS space that should have been tested against the the state of the art in (commercially backed) networking space. From the abstract: > However, none of these systems offer a general-purpose datapath OS re

Exactly this happened to me. We bought the TV and for years things were great. Really loved the functionality of the smart TV. Being able to stream YouTube at a moments notice was great. But then the adverts started. We paid $3000 for this

Basically the entire internet is built on TCP. But TCP wasn't always very good. There was a time when congestion nearly killed the early internet. Congestion avoidance and control talks about how they fixed it. It's light hearted,

I think you're missing the point. I'm talking about the concept of mathematically modelling the program first, before writing it (as per the article). This process only applies to certain types of applications, ones that are roote

What I'm discussing here is the general concept of modelling your program formally before writing it (as per the article). What I'm arguing is that this type of approach is only possible for a certain set of applications which tak

How so? Can you give an example?

Thinking in math first has been the catch cry of functional programmers (and their formal logic/verification friends) for decades. And there's nothing wrong with it, unless the problem you are trying to solve actually requires per

Yes! This and only this! The posted "bit hacks" are little more than bit level manipulations exactly as intended. The Stanford hacks are truly excellent. My favourite is: https://graphics.stanford.edu/~seander&#x2F

Congestion avoidance and control, by Van Jacobson looks at how TCP, the fundamental protocol behind the internet, works (or didn't work to begin with). It's a pretty easy paper to digest without too many dependencies, especially i

FPGAs are not a new thing. But FPGAs that are big enough and fast enough to outperform ASICs (in the networking context) is a new thing. Re the title. It's perhaps a bit poetic, but it's not misleading. What else could the title p

NetFPGA is a great development board with a lot of features. Unfortunately its size and research quality software/firmware do not make it a suitable device for deployment at scale into production environments.

Ha. Thanks yes. Too busy selling stuff to get around to fixing the website. It's on the list of things to do...

The company I work for builds exactly that. NICs, which are actually FPGA's with area larger than what is necessary to build the NIC alone. Our customers then either just use the NIC or add custom firmware for their own applications.

This idea was the subject of a paper at a major systems conference. The paper is called "Scalability! But at what cost?" - It goes well beyond this simple example above to explore how most major systems papers produce results that

IMHO, a good manager would communicate the importance of the project along with the spec of the project. "Because I said so, so do it" is not a good strategy for highly skilled, highly competent, highly intelligent people. The &qu

I won't give away the details, but the warm-up question should have taken a about 14 seconds for someone with the claimed skill set. They should have been able to speak the code at us rather than use a whiteboard. Think of something li

Xeon Phi is around and used in various financial computations. The problem with GPUs is not TDP, but programming flexibility. Programming a GPU is very hard to do well for generic computations, whereas x86 like CPUs have millions of program

Maybe they mean "effective" speed. 1000x 1.78GHz = 1.78THz. Assuming a job is embarrassingly parallel it might be an ok metric. Realistically, probably not.
