ASM? You mean assembly language? I haven't looked at that since my senior project! How arcane! And compilers are so smart anymore, why should I care?
I used to feel the same way...albeit with a latent desire to learn it as I wish I knew Latin. Then one day I found myself out of options on my SIMD code generation project. The compilers were great, but making progress was like building a ship in the bottle. I was playing a game I know you've played too: "Let's Guess What the Compiler Will Do"!
In my last blog, I introduced the concept of vectorization, which is parallelism across data elements in a register inside a single CPU core. It's a topic that I am very excited about this year, and in this blog I will expand on the subject to address what types of applications can take advantage of vectorization.
