GNU Make build system

SIMDx86 will be using GNU make as a build system from here on out. Still resolving issues with it as of right now, but you can check out the SVN for the code.

First 1000 downloads reached!

SIMDx86 has finally hit its first 1000 downloads! Thank you to all who have checked out the project and it source code. If you haven't seen SIMDx86, then now it is a good time! Try reading the documentation, download the v0.4.0 tree (0.5.0 is under development), or get the bleeding 0.5.0 tree from Subversion (no seatbelts provided!)

Subversion (SVN) access enabled

SVN access has been enabled and will continue to be the prefered method of downloading unofficial/developmental versions of SIMDx86. The initial import contains the v0.5.0 prealpha tree, BUT IS LIKELY NOT TO COMPILE CORRECTLY AS WELL. If you are looking for stable releases, you should wait until the official release via the Sourceforge file release system.

libSIMDx86 v0.4.0 Released!

SIMDx86 version 0.4.0 has been released. This is the last major release before the huge architectural updates that occur in 0.5.0. This release bugfixes and accelerates numerous functions. See the changelog included in the package.

Future: libSIMDx86 0.4 -> 0.5 changes

There are going to be some major architectural changes in the way SIMDx86 works in version 0.4.0 -> 0.5.0.

You will still have the wonderful static link, but there is just a single unified binary. This binary contains the optimal code for ALL instruction sets/processors. At runtime, the optimal code is overlayed using VirtualProtect
() (Win32) and mprotect() (UNIX, Linux). This gives all the speed of statically linked code (no indirect function calls, i.e. function pointer or DLL/SO), and all the flexibility of a DLL/SO. This will require a massive overhaul of the existing code and some other things.... read more

libSIMDx86 v0.4.0 Prerelease available!

The prelease of version 0.4.0 is now available. This code isn't fully accelerated by any means, but is a good sneak peak as to what to expect. There will be no binaries for 0.4.0 prerelease. Please don't use this code in production quality programs just yet!

Posted by Patrick 2006-09-13


SIMDx86 development and release of version 0.4.0 will be temporarily halted due to a two week vaction. Sorry to all who were in fact waiting for this.

Hopefully when I return, there will be Solaris 10/x86 GCC binaries available too. Hopefully.
