Yes, I do need access to your AVX2 machine. My public key is in the attachment. As for SDE, it might be a good alternative if network connection to your server is too lagging (thanks to China's GFW). I'll give it a try.

I also thought of this before. I think the hard part is to identify which code to be offloaded. Anyway, I'll see what I can do.
