UC Santa Cruz researchers show that it is possible to eliminate the most computationally expensive element of running large language models, called matrix multiplication, while maintaining performance.
There is an interesting thread on the Go issue tracker about daemonizing processes. Most of the thread is not about daemonizing processes though, but more about why Go has no Fork() function which you can call directly in your code. The first time I read through it I was wondering and saying to myself: “Yeah, why is…
RAD Game Tools' web page. RAD makes Bink Video, the Telemetry Performance Visualization System, and Oodle Data Compression - all popular video game middleware.
I wanted to explore different ways of communicating between different processes executing on the same machine, and doing so as fast as possible. We're focussing on high speed inter-process communication (IPC), but some of these approaches can be extended across a network. We'll do this exploration in Rust.
Discussions of coroutines and user-mode threads — like Project Loom's virtual threads or Go's goroutines — frequently turn to the subject of performance. The question I'll try answering here is, how do user-mode threads offer better application performance than OS threads?
Read how we built a flexible, high-performance columnar compression mechanism for PostgreSQL to add scalability to our favorite database.
How vLLM reaches 2.2k tokens per second per H200 for DeepSeek-style MoE serving with Wide-EP, async scheduling, dual-batch overlap, disaggregated serving, CUDA
The October 2012 Xbox 360 dashboard update moved the dashboard from the nand flash to the hard-drive. Does it make a difference?
Update, February 2019: Two years later the VC++ bug I reported here still exists, even in VS 2019 preview. However Chromium no longer builds with VC++ so I’m reverting the changes where I del…
I recently blogged about why I believe the future of cloud data services is large-scale and multi-tenant, citing, among others, S3. “ Top tier SaaS services like S3 are able to deliver amazing simplicity, reliability, durability, scalability, and low price because their technologies are s
How T2 burstable instances and CPU credits really work, with a worked example of a busy t2.micro running out of credits and grinding to a halt.
Run, compile, and link C programs instantly with CJIT.
Over two years ago I installed Acronis True Image for Crucial in order to migrate my data to a new SSD I had just purchased. It worked. I then left True Image installed “just in case”, and what har…
One of the most common reasons for opening Activity Monitor is to check the % CPU of processes that might be running out of control. How accurate are those figures, though, and should you believe t…
One of the headline features of CockroachDB is its full support for ACID transactions across a distributed database. In this post, we’ll explain...
How wanting more is not always better
Concurrent operations can be grouped relatively neatly into categories based on their cost
This week’s paper review is the second in a series on “The Future of the Shell” (Part 1, a paper about possible ways to innovate in the shell is here ). As always, feel free to reach out on Twitter with feedback or suggestions about papers to read! These weekly paper reviews can also be delivered weekly to your inbox .
I have been curious about data compression and the Zip file format in particular for a long time. At some point I decided to address that by learning how it works and writing my own Zip program. The implementation turned into an exciting programming exercise; there is great pleasure to be had from creating a well…
Addendum: I've added a few additional tips for conference papers chairs, papers committee members, and papers sorters .
David Baron put this up in Mozilla’s San Francisco office a while back:
Microsoft is losing Builders fast. They're switching to MacOS and Linux. The biggest pull keeping people on Windows, outside of shear inertia, is content creation and gaming. However, even these are falling to Linux.
