I was able to get it to work in simple tests on Windows, but not when linked in with Bitcoin. It may have a better chance of working as part of a C program instead of C++.<br/><br/>Currently it's only enabled in the Linux build, so if you get it to work you could make it available to Windows users. It's about 100% speedup on AMD CPUs.</div> text/html
