Very much looking forward to being part of the FoC conference in Munich this year!
Our line-up for the Future of Computing Conference 2024 is growing – here are the first 10 computing startups that will pitch: @anabrid_tech @semron_ai @SpiNNcloud GEMESYS @synthara Lumai @Akhetonics NcodiN Linque @sim_bricks If you’d like to pitch your computing startup, please get in touch with me or my co-organizers, Tobias Wölfel and Christopher Trummer from TUM Venture Labs and Oliver Hasse from @INAMBerlin #FuCon2024

Today, Hejing Li introduces the SimBricks orchestration framework and how it enables users to simulate even complex systems with ease! This is a key feature to manage the complexity of connecting together multiple simulators. Read More: simbricks.github.io/blog/orc…

I always forget: is UW in Switzerland or Germany?

The start of our "meet the team" series. Over the next weeks the rest of the team will follow! You can look forward to @li_hejing 's spotlight next week!

SimBricks accelerates development of heterogeneous systems and reduces cost. Virtual prototypes in SimBricks enable systems & hardware architects to make informed design decisions, and bridge different HW and SW teams. Learn more: simbricks.github.io/blog/acc…

While we were presumably mistagged, we are still happy to recommend this library. 😅
If you get a chance to visit one place while in Prague 🇨🇿 @sim_bricks would highly recommend visiting the majesty of the klementinum library prague.eu/en/object/places/4… Breath taking @SESAMSimulation #sesam2024 @PragueEU

With this release we have moved on from an initial research prototype, to now a tool that can be and is already used by independent users. Our goal is to make it simple for users to get started with full-system simulation without needing expertise for each and every simulator.

We are testing our systems methodology for building and evaluating HW accelerators in a classroom setting, focusing on end-to-end system behavior throughout. The project also provides an easy (open source!) starting point outside of teaching. gitlab.cs.uni-saarland.de/os… (1/n)
We released the final HW acceleration course project milestone: gitlab.cs.uni-saarland.de/os…. Here, the students implement Verilog RTL for the accelerator and synthesize it in 130nm, determining feasible clock rate and chip area and putting these in context of full system performance.

This course is using SimBricks to provide students with hands on experience of exploring the complete systems stack for HW acceleration: designing a HW/SW interface, implementing drivers, implementing HW simulation models, and finally implementing actual HW RTL!
🚨New Course Alert🚨 @AntoineKau is teaching a course on Accelerating Applications with Specialized Hardware (cms.sic.saarland/hwaccel_23/). The project uses @sim_bricks and will be released in parts over the course of the semester. More info on the project: cms.sic.saarland/hwaccel_23/…

Ah and Bin is on Twitter after all: @csbingao
Today Hejing presented our first paper on SimBricks at #sigcomm2022. The paper and open-source code are linked on our website: simbricks.github.io/. Please reach out if you are interested in using SimBricks.

In particular, SimBricks runs the complete software stack including the unmodified operating systems, drivers, and applications. With the open-source corundum NIC we've also shown that we can simulate existing custom HW systems not built for simulation. 3/n

The paper further probes various technical aspects. Among other things we demonstrate scalability to up to 1000 simulated hosts (>1000 interconnected simulator instances.) with only minimally longer simulation times compared to simulating 40 hosts.
