Announcing the release of RyuJIT for x64!

After many years of work, RyuJIT for x64 has now been released! Thanks to many of you trying it out over the course of the last couple years via our CTP releases, and giving us valuable feedback.

RyuJIT and .NET 4.6

It’s been a while since we’ve posted here, and a lot has happened with RyuJIT since the last post. First and foremost, RyuJIT is the default x64 JIT for .NET 4.6! As a result, there is no need to use a RyuJIT CTP to try out RyuJIT. If you install the .NET 4.6 Preview (included…


RyuJIT CTP5: Getting closer to shipping, and with better SIMD support

Hi Folks!  Yes, we understand it’s been a while since we shipped the last RyuJIT CTP.  We have been working hard on improving our SIMD support and getting RyuJIT to ship quality for the next version of the .NET Framework.  So without further ado, here’s a quick description of what you can expect from RyuJIT…

RyuJIT CTP4: Now with more SIMD types, and better OS support!

Hi, folks. It’s been a busy month around here. We’ve been working on all sorts of stuff that I can’t talk about right now, but in the meantime, we’ve also been responding to feedback on the SIMD types. So, since it’s busy, I’m just going to list off the details, and link to other places…

Quick info about a great SIMD writeup

Hi, folks. I wanted to put together a more coherent version of a random Twitter conversation I had with Sasha Goldshtein. First, you should go read Sasha’s excellent write-up on SIMD: http://blogs.microsoft.co.il/sasha/2014/04/22/c-vectorization-microsoft-bcl-simd/. He’s done an excellent job of talking about how scalar & vector operations compare, and really dug in deep to performance of the…

RyuJIT CTP3 minor fix

Hi, folks. I’m on vacation, but I figured I’d let everyone know what the RyuJIT team has been up to since the beginning of the week. There was a pretty nasty bug that slipped through into CTP3 that I’ll let someone else explain in more detail because I’m tired (something about tail-calling delegates). If you…

RyuJIT CTP3: How to use SIMD

SIMD details will be forthcoming from the .NET blog, but Soma’s already showed some sample code, and everything’s available, so until those details are available here are directions about how to kick the SIMD tires: Go get RyuJIT CTP3 and install it (requires x64 Windows 8.1 or Window Server 2012R2, same as before) Set the…

Lies, damn lies, and benchmarks…

Hi, Folks! We just released RyuJIT CTP2, complete with a magical graph indicating the performance of the new 64 bit JIT compiler as compared to JIT64. I figured I’d describe the benchmarks we’re currently tracking in a little more detail, and maybe include some source code where it’s code that it’s okay to share. Before…

RyuJIT FAQ is on the .NET Blog

Go forth and read it to see if it answers your questions: http://blogs.msdn.com/b/dotnet/archive/2013/11/18/ryujit-net-jit-compiler-ctp1-faq.aspx One thing that’s buried in the FAQ: we fixed bugs that people reported, so if you uninstall RyuJIT CTP1, re-download it and reinstall it, you’ll get an ever so slightly less buggy version! If the FAQ doesn’t answer your questions, I’ll answer other questions…
