Hi all, I've written a simple class that encapsulates the cpuid instruction. It could probably be improved and polished, but I'm fairly happy with it. One thing I'm considering is if a static only class would be better, it's not like the info can change dynamically... Get it here: http://famolsen.dk/d/cpuid.zip The zip contains the cpuid module and a simple test app. Running the test app I get personally get this: Vendor string: AuthenticAMD Processor string: AMD Athlon(tm) 64 X2 Dual Core Processor 3800+ Features: MMX SSE SSE2 SSE3 3DNow! 3DNow!+ MMX+ AMD64 HTT Multithreading: 2 threads / 2 cores The threading info should work on both Intel and AMD cpus, but I have no way to test the Intel path. Any feedback would be much appreciated. Also, I'm considering creating a library with sse/2/3 optimised batch operations for vector operations normalisation etc. Would such a library be of interest to the D community?

But, make sure you're not just reinventing the wheel, since it's such a well-explored problem. I think it would make sense for D to come with a simple BLAS implementation for general use. I just found one little BLAS1 implementation that's under a BSD license: http://iridia.ulb.ac.be/~fvandenb/miniSSEL1BLAS/miniSSEL1BLAS.html which looks as though it is D-compatible and easy to port. No doubt there are many others on the net.

Walter Bright wrote:I'd like to put this into Phobos. Can you explicitly make it public domain?Cool :) I have updated the zip and CPUID is now public domain. There is one more thing (at least) that should be implemented though before this is really worthy of being in std (IMHO). The threading info is only probing the hardware. The OS might not allow the app to use those resources so processor affinity stuff should be added. I can add this, just have to read up on it. Or if someone knows it already feel free to patch, in which case I will do nothing :P
